Rolling ball sculpture
 | This article needs additional citations for verification. (August 2010) |
A rolling ball sculpture (sometimes referred to as a marble run, ball run, gravitram, kugelbahn (German: 'ball track'), or rolling ball machine) is a form of kinetic art – an art form that contains moving pieces – that specifically involves one or more rolling balls.
A version where marbles compete in a race to win is called a marble race, in which the marbles go through simple or complex labyrinths, seeing which one is the winner, or even loser. The YouTube channel Jelle's Marble Runs has popularized this idea over the years, especially gaining traction during the COVID-19 lockdown of 2020. Through his video series dubbed "Marble League", also known as the "MarbleLympics", he recorded and uploaded marbles racing through tracks, with them resembling Olympic sports and were recorded in a sports broadcast-like manner (a commentator to educate viewers on what's happening, crowd noises and other SFX as if it's a real like sporting event, etc).[1][2]

The regular rolling ball sculpture rolling ball structure is usually constructed out of wood, plastic, or metal, with the balls used traditionally being small glass spheres. The objective of it is to load a ball into the sculpture, and then allow gravity to make its way down, usually going through various forms of tracks, like, for example, a long twisty channel leading to a shallow funnel.
World records
[edit | edit source]
The tallest rolling ball sculpture in the world, at 22 metres (72 ft) tall, is named the Energy Machine, and located in the Hong Kong Science Museum in Hong Kong.[3] The structure consists of two towers, balls moving among them.[4][5] It is also the largest of its kind in the world.[5] The machine contains stream of ball, demonstrating energy conversion, from potential energy to kinetic, sound, light energy, with balls rolling along tracks.[5]
According to Guinness World Records, the longest marble run is 2,858.9 meters long and was completed in Switzerland in September 2017.[6][7]
