Wrecking ball

A wrecking ball is a heavy steel sphere, typically weighing from 1,000 to 13,500 pounds (450 to 6,100 kg) and measuring about 3 to 6 feet (0.9 to 1.8 meters) in diameter, suspended by a chain or cable from a crane and employed in demolition to smash concrete, masonry, and other structures by swinging or dropping it with pendulum-like force.^[1]^[2] Originating in the late 19th or early 20th century— with disputed claims including a 1889 development by the British firm Henry Bath & Son for breaking up ships and an early 1900s innovation, claimed by American wrecker Jacob Volk, for urban buildings— the wrecking ball rose to prominence in the 1940s and peaked during the post-World War II construction boom of the 1950s and 1960s, when it symbolized efficient urban renewal by rapidly reducing large edifices to rubble without extensive manual labor.^[3]^[4] In operation, the ball is hoisted by a crane—whose rated load must support at least twice the ball's weight for safety, per Occupational Safety and Health Administration standards— and either freely dropped vertically onto roofs or slabs or swung laterally into walls, converting gravitational potential energy into kinetic impact to fracture materials, though reinforcing steel often requires separate cutting tools afterward.^[5]^[6]^[2] Despite its effectiveness for large-scale, open-site demolitions—such as the 1959 takedown of New York City's Toots Shor Restaurant, where the ball was playfully painted with baseball stitching— the method generates significant dust, vibration, noise, and debris scatter, posing hazards like flying projectiles and structural instability if not precisely controlled by skilled operators.^[3]^[2] By the late 20th century, wrecking balls began declining due to environmental regulations on asbestos and toxins in older buildings, the need for precision in dense urban areas near power lines or adjacent structures, and the advent of safer, more versatile alternatives like hydraulic excavators with shear attachments and controlled implosions, rendering the tool rare today except in select rural or industrial applications, such as the 2023 use of a 10-tonne (10,000 kg) ball at 75 meters height by a SENNEBOGEN 6300 HD crane in Europe.^[4]^[2]^[7]

History

Origins and early development

The wrecking ball emerged as a response to the escalating demands of the Industrial Revolution, particularly in shipbreaking and the nascent stages of urban renewal, where manual labor proved insufficient for dismantling large iron and steel structures. As industrial expansion accelerated in the late 19th century, the need for efficient methods to recycle metals from obsolete vessels and clear space for new infrastructure drove innovations in demolition technology.^[8]^[3] The first documented practical use of the wrecking ball occurred in 1888–1889 during the scrapping of the SS Great Eastern, a massive iron steamship designed by Isambard Kingdom Brunel, at the Rock Ferry yard on the River Mersey in England. Acquired by the British metals firm Henry Bath & Son for demolition, the ship's robust double hull resisted traditional hand tools, prompting the company's development of the wrecking ball to loosen rivets and separate plates. This marked the tool's debut as an effective mechanized alternative, taking over 18 months and involving around 200 workers operating round the clock.^[9]^[3]^[8] Early designs featured simple cast iron spheres, typically weighing several tons, suspended from steel cables attached to steam-powered cranes or stationary engines, allowing the ball to be hoisted and released to impact structures via gravity and pendulum swing. These rudimentary setups relied on the kinetic energy from controlled drops or swings to fracture materials, proving far more efficient than prior methods for heavy ironwork.^[9]^[10] By the early 1900s, the wrecking ball evolved from manual sledgehammers and picks—used by teams known as "barmen" for smaller-scale demolitions—into a mechanized staple for tackling larger urban structures amid rapid city growth, such as during New York's skyscraper boom. Firms like Jacob Volk Wrecking and Shoring Company in New York adapted the tool for building demolition, transitioning it from shipyards to construction sites and significantly reducing labor and time requirements.^[8]^[3]^[10]

Peak usage and decline

The wrecking ball reached the height of its popularity in the 1940s and 1950s, becoming a staple tool in post-World War II urban redevelopment efforts across the United States, particularly in densely built cities like New York and Chicago.^[4]^[11] This era saw explosive growth in demolition demands as aging infrastructure, including early 20th-century buildings and makeshift wartime structures, was cleared to make way for modern housing, highways, and commercial developments under federal urban renewal programs.^[12] In Chicago, for instance, wrecking balls were extensively used in slum clearance projects along areas like Halsted Street, where entire ethnic neighborhoods were razed to facilitate public housing and infrastructure expansions.^[13] Similarly, in New York, the method symbolized rapid progress, with thousands of structures demolished to reshape the urban landscape, including notable cases like the clearance of tenement slums in the 1950s.^[4] These large-scale initiatives displaced hundreds of thousands of residents and relied on the wrecking ball's efficiency in swiftly toppling multi-story buildings, often WWII-era relics or early skyscrapers, at a fraction of the labor-intensive cost of manual dismantling.^[12]^[14] By the 1960s, however, the wrecking ball's dominance began to wane as its limitations became evident amid evolving construction practices and regulatory pressures. Rising labor costs, exacerbated by the method's propensity for creating hazardous debris clouds and requiring extensive cleanup, eroded its economic advantages.^[11]^[8] The tool's imprecise targeting often led to uncontrolled structural collapses, posing risks to adjacent properties and workers, while also complicating material salvage efforts in an era increasingly focused on recycling and environmental concerns.^[4]^[11] The advent of hydraulic excavators with specialized attachments, such as shears and grapples, provided a safer, more controlled alternative capable of selective demolition without the widespread collateral damage.^[8]^[10] Usage trends reflect this shift dramatically: wrecking balls were a common fixture in U.S. construction fleets during the 1950s, integral to the era's thousands of urban renewal projects, but by the 2000s, they had become rare, relegated mostly to preliminary weakening of isolated structures in open areas.^[4]^[11] In developed countries, the method's application plummeted as mechanical innovations and stricter safety regulations prioritized precision over brute force, marking the end of an era when the swinging steel sphere defined demolition's spectacle.^[8]^[12]

Design and Construction

Materials and shapes

Wrecking balls are primarily constructed from cast or forged steel, chosen for their superior tensile strength and impact resistance, which enable the tool to endure repeated high-impact strikes without deforming or fracturing.^[15]^[10] Cast steel variants, such as ZG 270-500, provide a minimum tensile strength of 500 MPa, ensuring durability in demanding demolition environments.^[15] Early wrecking balls were made from cast iron, but designs have evolved to modern pear-shaped configurations formed from steel, enhancing overall effectiveness by minimizing the risk of the ball becoming lodged in debris during operation.^[16]^[10]^[11] The pear shape, often featuring a flat top, allows for better extraction through structures like roofs or slabs compared to traditional spherical forms.^[10] A key component is the central attachment point, typically an eyebolt, shackle, or removable pin, which secures the wrecking ball to the crane's cable or chain and is reinforced through welding or integral forging to withstand extreme stresses and prevent detachment failures.^[17]^[15] To further bolster durability, wrecking balls undergo surface treatments including heat tempering, which relieves internal stresses and reduces the propensity for cracking after prolonged impacts, alongside processes like sandblasting for surface integrity.^[15]^[17]^[18]

Sizes and weights

Wrecking balls typically range in weight from 1,000 to 15,000 pounds (450 to 6,800 kg), with the average weighing around 5,000 pounds (2,270 kg).^[10]^[1] Smaller balls under 2,000 pounds (900 kg) are suited for light structures such as wooden or brick buildings, while larger ones exceeding 8,000 pounds (3,600 kg) are employed for heavy concrete reinforcements.^[1] Diameters generally vary from 2 to 5 feet (0.6 to 1.5 meters), with an average of about 3 feet (0.9 meters), scaled according to the height of the target building and the density of its materials to optimize impact force.^[1]^[19] Selection of wrecking ball size and weight depends on the structure type, crane capacity, and demolition precision required; for instance, balls weighing 4,000 to 6,000 pounds (1,800 to 2,700 kg) are commonly chosen for mid-rise buildings to balance efficiency and control.^[1]^[5] In certain projects, heavier custom balls exceeding 10,000 pounds (4,500 kg), such as a 19,800-pound (9,000 kg) example used in 2023 demolition, have been utilized for exceptionally robust structures.^[20]^[7]

Method of Use

Traditional demolition techniques

In traditional demolition, the wrecking ball is suspended from a crane's lifting hook by a steel chain or cable at an appropriate height to enable effective operation, with the crane operator controlling the hoist mechanism for raising and lowering as well as the swing for targeted impacts.^[10]^[21] The pendulum method relies on swinging the ball in controlled arcs to deliver lateral blows to building walls and supports. The operator hoists the ball and pulls it back toward the crane cab before releasing it, allowing gravity to accelerate the ball through an arc and generate impact via concentrated kinetic energy, which fractures masonry and concrete.^[10]^[21]^[22] The free-fall technique involves hoisting the ball directly above the target area and dropping it vertically for precise, downward impacts, often starting at upper floors to collapse sections progressively from top to bottom.^[10]^[21] The demolition process begins with initial high-level strikes using either method to weaken the overall structure, followed by systematic passes to break down remaining elements into manageable debris for subsequent cleanup.^[10]^[23]

Specialized applications

In quarrying operations, particularly during the 20th century, the drop-ball method employed wrecking balls or similar heavy weights hoisted by cranes and released to fracture rock faces and oversized boulders after primary blasting. This technique was especially prevalent in hard rock deposits where blasting alone left material too large for processing, allowing for secondary breaking without additional explosives. For instance, historical accounts from British quarries describe the introduction of drop-ball hammers attached to wire ropes for efficient rock fragmentation, a practice that persisted into mid-century mining before hydraulic breakers became more common.^[24]^[25] Aerial demolition represents a specialized adaptation for remote, hazardous, or confined sites inaccessible to ground-based equipment, where helicopters hoist and drop wrecking balls to target structures precisely. The Kaman K-MAX, with its 6,000-pound external load capacity, has been notably used in such operations, enabling rapid deployment in urban or environmentally sensitive areas. A prominent example occurred in 2008 in Louisville, Kentucky, when a K-MAX helicopter systematically demolished a 100-year-old brick chimney using a 5,500-pound slung wrecking ball, minimizing ground disruption and facilitating subsequent school construction.^[26]^[27] In shipbreaking, wrecking balls have been adapted to dismantle large vessels, particularly those with robust iron or steel hulls resistant to manual or cutting methods. An early and influential application was the scrapping of the SS Great Eastern in 1889 on the River Mersey in Liverpool, where Henry Bath & Son Ltd. pioneered the wrecking ball to overcome the ship's double-hulled design. Workers hoisted a heavy ball via crane and steam engine, releasing it to spring rivets and separate plates; this noisy, labor-intensive process took 200 men nearly two years, marking the first documented use of the tool and influencing later demolition practices.^[28] Despite their decline in general use, wrecking balls retain niche roles in modern demolition for controlled scenarios involving inaccessible concrete structures, such as stadium roofs. In 2014, the Hubert H. Humphrey Metrodome in Minneapolis was partially demolished using a wrecking ball after initial explosive charges removed the roof, allowing crews to raze the remaining walls and foundation efficiently with cranes. This method was selected for its balance of speed and control in an urban setting, completing the project ahead of schedule while recycling materials. In 2023, a 10-ton (9,000 kg) wrecking ball was used at a height of 75 meters by a SENNEBOGEN 6300 HD crane for industrial demolition in Europe.^[29]^[7]

Safety Considerations

Hazards involved

The primary hazards in wrecking ball operations stem from the potential for uncontrolled swings of the heavy steel sphere, which can lead to rebound effects or cable snaps, propelling debris significant distances and endangering operators, workers, and bystanders. For instance, in a 2007 incident in Pennsylvania, a 1,500-pound wrecking ball detached from its crane cable and rolled downhill, colliding with multiple vehicles and injuring three individuals, highlighting the risk of the ball itself becoming a projectile.^[30] Similarly, flying debris from impacts can travel considerable distances, posing struck-by hazards that contribute to injuries in demolition zones.^[31] Structural collapse during wrecking ball demolition presents unpredictable risks, as partial failures in weakened buildings can result in sudden and cascading falls of materials, potentially trapping or injuring personnel on site. Historical examples underscore this danger; in a 2004 case documented by the National Institute for Occupational Safety and Health (NIOSH), a 225-pound headache ball—used similarly to a wrecking ball—fell due to a crane malfunction, striking and killing a construction laborer when the anti-two-blocking device failed, illustrating how equipment issues can trigger unintended collapses or falls.^[32] Progressive weakening of structures has led to unanticipated failures affecting multiple workers in older demolition practices. Environmental hazards associated with wrecking ball use include the generation of substantial dust clouds from repeated impacts on concrete and masonry, which often contain respirable crystalline silica, leading to potential long-term respiratory issues like silicosis for exposed workers. Demolition activities, including those involving wrecking balls, have been identified as significant sources of silica dust emissions, with airborne particles posing inhalation risks during the fracturing of silica-containing materials.^[33] Additionally, the operations produce high noise levels, frequently exceeding 100 decibels from the ball's impacts and crane movements, which can cause immediate hearing damage with even brief unprotected exposure.^[34] Equipment failure, particularly cable fatigue or crane overload, represents a critical risk in wrecking ball operations, as the dynamic loads from swinging the ball can exceed design limits, leading to snaps or breakdowns. California Division of Occupational Safety and Health (Cal/OSHA) standards emphasize the need for twice-daily inspections of load lines and balls precisely because fatigue and overload have historically contributed to accidents, such as the detachment events that propel the ball uncontrollably.^[35] In the 20th century, such failures were a recurring factor in construction fatalities, often tied to inadequate maintenance under repetitive high-stress conditions.^[36]

Precautions and regulations

Operator training is a critical precaution in wrecking ball demolition, requiring mandatory certification for crane handling and site assessment to ensure competent operation and hazard recognition. Under OSHA standards, employers must ensure that each crane operator is trained to recognize hazards, certified or licensed by an accredited body, and evaluated for safe operation before using equipment in demolition activities.^[37] This requirement stems from the broader framework established by the Occupational Safety and Health Act of 1970, with specific crane operator certification rules formalized in 29 CFR 1926 Subpart CC, effective for construction and demolition since 2010.^[38] Site controls are essential to protect workers and nearby structures, including the establishment of exclusion zones covering the swing radius of the wrecking ball to restrict access during operations, such as zones at least 1.5 times the swing radius in some jurisdictions like Hong Kong.^[39]^[40] Spotters must be deployed to monitor the ball's path and alert operators to potential issues, while vibration monitoring equipment is used to detect and mitigate risks of damage to adjacent buildings from impact-induced ground motion.^[41] These measures align with OSHA's general demolition requirements under 29 CFR 1926.850, which prohibit workers in areas affected by mechanical demolition.^[42] Equipment inspections form the backbone of regulatory compliance, with daily visual checks required for cables and the wrecking ball to identify wear, cracks, or other defects. Cables must be rated with a safety factor of at least 5:1 relative to the load, ensuring they can withstand dynamic stresses during swings, and undergo documented monthly inspections per OSHA guidelines.^[43] Wrecking balls are inspected for structural integrity, with replacement upon detection of cracks to prevent failure.^[43] International regulations further standardize precautions, such as the EU Machinery Directive 2006/42/EC, which mandates fail-safe mechanisms like emergency stops and overload protection on demolition cranes to enhance operator control and prevent uncontrolled swings.^[44] In the United States, safety concerns have contributed to a decline in the use of wrecking balls in densely populated urban areas since the 1980s, with some municipalities favoring alternative methods to reduce risks to infrastructure and the public.

Alternatives to Wrecking Balls

Modern demolition methods

One of the primary modern demolition techniques involves the use of hydraulic excavators equipped with specialized attachments such as shears or grapples, which enable precise cutting and dismantling of steel and concrete structures. These machines, often crawler-based, allow operators to methodically break down buildings from the top down, minimizing uncontrolled collapse and facilitating material sorting at the site. Shears are particularly effective for slicing through metal beams and rebar, while grapples grip and crush reinforced concrete elements, making this approach suitable for urban environments where space is limited. Hydraulic excavators with these attachments have become the most common method for demolition in North America, employed in the majority of projects due to their versatility and efficiency.^[45] Explosive implosion represents another key advancement, utilizing controlled detonations of strategically placed charges to bring down tall structures inward, reducing the footprint of debris and enabling rapid clearance in densely populated areas. This method involves detailed engineering to weaken key support columns, causing the building to collapse under its own weight in seconds, followed by extensive pre-weakening to ensure safety. A notable example is the 1998 implosion of the J.L. Hudson Department Store in Detroit, Michigan, a 33-story building that was the tallest structure demolished by explosives at the time, using over 2,700 pounds of charges across 1,500 detonations to create a contained rubble pile.^[46]^[47] Mechanical methods like diamond wire sawing provide surgical precision for selective demolition in sensitive or confined spaces, where traditional heavy machinery might cause excessive vibration or damage to adjacent structures. These systems employ a looped diamond-impregnated wire pulled through the material at high speed, allowing clean cuts in thick concrete or stone up to several meters deep with minimal dust, noise, and flying debris compared to impact-based techniques. This approach significantly reduces overall waste generation by producing smoother edges that require less post-processing, and it is often used for removing specific sections like bridge supports or nuclear facility components without full-scale disruption.^[48] Emerging post-2010, robotic and remote-controlled systems have further enhanced safety and accessibility in demolition, particularly for hazardous interiors or elevated work. Compact demolition robots, such as those from Brokk, are electrically powered and maneuverable through standard doorways, fitted with attachments like hydraulic breakers or grapples to dismantle structures remotely via radio control, keeping operators away from risks like falling debris. As of 2025, these systems have increasingly incorporated artificial intelligence for real-time structural assessment, autonomous waste sorting, and precise deconstruction, improving efficiency in construction and demolition waste management while prioritizing worker protection. Drones complement these by scouting unstable areas for structural assessments prior to intervention, while mini-excavators with remote operation handle fine interior work in contaminated or confined sites. These technologies have gained traction in industrial and nuclear decommissioning projects, prioritizing worker protection and precision.^[49]^[50]^[51]

Reasons for replacement

The replacement of wrecking balls in demolition practices has been driven primarily by superior safety profiles of alternative methods, which minimize worker exposure to hazards associated with the unpredictable pendulum motion of a suspended ball. Traditional wrecking ball operations often result in struck-by incidents and structural collapses due to imprecise impacts, contributing to higher injury rates in historical data; for instance, analysis of 653 U.S. Occupational Safety and Health Administration (OSHA) demolition accidents from 1984 to 2012 revealed that struck-by objects accounted for 19.91% of incidents, many linked to uncontrolled equipment swings.^[52] In contrast, modern mechanical methods, such as excavator-based demolition, allow operators to remain in protected cabs, significantly reducing on-site personnel exposure to falling debris or unstable structures and thereby lowering overall accident risks.^[53]^[54] Modern alternatives also offer greater precision and speed, enabling controlled dismantling that avoids excessive collateral damage to adjacent properties—a common issue with wrecking balls' broad, indiscriminate swings. Mechanical demolition using attachments like hydraulic shears or grapples completes projects more rapidly than the labor-intensive setup and repeated swings required for wrecking balls, often reducing timelines from weeks to days for comparable structures.^[4]^[54] This efficiency translates to lower costs per ton of material demolished, as excavators minimize rework from unintended damage and streamline debris handling compared to the scattered rubble typical of ball methods.^[54] Environmentally, wrecking balls generate substantial dust and noise from repeated high-impact collisions, complicating compliance with regulations such as the U.S. Environmental Protection Agency's (EPA) standards for stormwater and particulate matter control at demolition sites.^[55] Contemporary techniques, including high-reach excavators and selective deconstruction, produce lower emissions by containing debris at the source and enabling better dust suppression, aligning more readily with 21st-century clean air requirements and reducing community disruptions.^[4] Economically, the shift offsets initial machinery investments through substantial labor reductions, as wrecking ball operations historically demanded large crews (often 10–20 workers) for rigging, swinging, and cleanup, whereas modern equipment typically requires only 2–3 operators per machine.^[53] This downsizing not only cuts payroll but also lowers insurance premiums by mitigating high-risk exposures, making alternatives more viable for urban projects where space and time constraints amplify traditional method inefficiencies.^[54]

Cultural Impact

In popular media

In music, the wrecking ball has been employed as a powerful metaphor for emotional destruction and transformation. Miley Cyrus's 2013 single "Wrecking Ball," from her album Bangerz, uses the image of a wrecking ball to represent the intense, demolishing force of love and heartbreak, with lyrics like "I came in like a wrecking ball / I never hit so hard in love," conveying regret and the crumbling of a relationship.^[56] The track, written by MoZella, Sacha Skarbek, Stephan Moccio, Dr. Luke, and Cirkut, became a commercial success, debuting at number 50 on the Billboard Hot 100 and rising to number one for three weeks, marking Cyrus's first chart-topping hit.^[57] In film, wrecking balls and demolition imagery have symbolized personal and societal breakdown. David Fincher's Fight Club (1999) includes striking demolition montages at its climax, where corporate buildings collapse in a spectacle of urban renewal and anarchic destruction via implosions, underscoring themes of consumerist collapse and rebirth. Documentaries and reality television have captured the wrecking ball's role in real-world demolition, often highlighting its dramatic impact in unexpected settings. The 1980 comedy The Blues Brothers, directed by John Landis, includes a memorable chase scene through the abandoned Dixie Square Mall in Harvey, Illinois, which was later demolished using a wrecking ball in 2012 after decades of decay, symbolizing the end of an era for American retail spaces.^[3] In literature, the wrecking ball serves as a motif for urban progress and disruption during the early 20th century. John Dos Passos's 1925 novel Manhattan Transfer portrays New York City's rapid transformation through industrialization, reflecting the chaotic energy and social upheaval of the 1920s Jazz Age amid relentless demolitions.

Symbolic uses

The wrecking ball has emerged as a potent symbol in architectural discourse, particularly during the mid-20th century urban renewal era, where it represented both aggressive modernization and the erasure of historic fabric. In the 1960s, widespread demolition projects across American cities, often justified as progress, sparked backlash from preservationists who viewed the wrecking ball as an icon of cultural loss and gentrification's destructive force.^[58] A landmark example occurred in Grand Rapids, Michigan, in 1969, when activist Mary Stiles Kimmell handcuffed herself to a wrecking ball poised to demolish the Old City Hall, a gesture captured in a globally circulated photograph that galvanized the historic preservation movement and highlighted community resistance to unchecked urban redevelopment.^[59] This imagery underscored the tension between renewal and heritage, influencing policies like the National Historic Preservation Act of 1966, which aimed to curb such demolitions.^[58] In contemporary art, the wrecking ball evokes themes of transience, deconstruction, and societal critique, often contrasting with more ephemeral interventions that highlight impermanence without destruction. Artists have repurposed its form to symbolize the fragility of structures—both physical and cultural—challenging viewers to reconsider what deserves demolition. For instance, in Tony Albert's 2020 video installation You Wreck Me, the artist parodies Miley Cyrus's "Wrecking Ball" by swinging on an exercise ball to shatter statues of colonial figure Captain James Cook, using humor and demolition motifs to address the transient nature of monuments and the need to dismantle colonial legacies.^[60] Similarly, James Nares's 1976 film Pendulum, featured in the 2015-2016 MoMA PS1 exhibition Greater New York, captures a massive wrecking ball-like sphere swinging through a TriBeCa alley, serving as a meditative symbol of urban transformation and the inevitable decay of old cityscapes.^[61] These pieces draw on the wrecking ball's raw power to explore ephemerality, echoing broader artistic traditions like the temporary wrappings of Christo and Jeanne-Claude, which temporarily alter landmarks to emphasize their fleeting presence in time.^[62] Politically, the wrecking ball functions as a metaphor for radical dismantling of entrenched systems, policies, or barriers, evoking forceful change in rhetoric from leaders across ideologies. In his 1987 speech at the Brandenburg Gate, President Ronald Reagan urged Soviet leader Mikhail Gorbachev to "tear down this wall," employing demolition imagery to symbolize the end of ideological divisions, though not referencing the wrecking ball literally; this phrasing has since inspired analogous uses of the tool as a emblem of policy upheaval. More recently, in a November 2025 address, President Joe Biden described former President Donald Trump's actions as taking "a wrecking ball" to American democracy and institutions, framing the literal 2025 demolition of the White House's East Wing as a broader allegory for disruptive governance.^[63] Such metaphors underscore the wrecking ball's role in political discourse as a vivid stand-in for aggressive reform or critique. In modern activism, environmental and social justice groups have adopted mock wrecking balls to protest overdevelopment and unsustainable policies, wielding the symbol to dramatize threats to communities and ecosystems. During the April 2024 World Bank/IMF Action Day protests in Washington, D.C., Friends of the Earth and allies deployed a giant prop wrecking ball to represent the demolition of harmful global development practices, advocating for alternatives that prioritize environmental protection over exploitative growth.^[64] This tactic builds on earlier preservation efforts, like 1960s campaigns against landmark losses, to highlight how overdevelopment perpetuates gentrification and ecological harm in the 2020s.^[65] Additionally, in video games, the wrecking ball appears as a character in Overwatch (introduced 2018), a hamster-piloted mech ball that embodies chaotic demolition, further embedding the symbol in popular culture.^[66]
