The Largest great ball contraption (GBC) has been created at LEGO® World Denmark in Copenhagen with modules including multiple bridges, rotating wheels, and a shot into a basketball hoop. This largest ball contraption made up of a staggering 259 modules takes 40 minutes for a ball to pass all the way through. The brains behind this amazing concept are Maico Arts and Ben Jonkman (both Netherlands), Klaus Hansen, Lasse Deleuran, Brian Soholm Larsen and Elena Dimitrova (all Denmark). It might take a few hours to several weeks or even months to build just one module depending on the complexity and size. Whoever builds this great ball contraption module on their own at home, and then put them together in one circuit. To set up a circuit like this takes a long time. They started in the morning on the day before opening and ended late in the evening on that day. A great ball contraption (GBC) is a made of LEGO® Technic components, and, at its simplest, has just one aim: to get balls from the beginning to the end of the device. It must meet certain criteria, with six main rules to qualify as a great ball, including that each module needs an “in-basket” to receive the balls, which must adhere to a set size and placement. People should strive to make their modules as interesting and intricate as possible to achieve GBC’s of impressive size and complexity it is not simply getting the ball from A to B. Modules are the components that make up the GBC, much like LEGO® bricks within a LEGO® structure. With this huge GBC, Maico Arts set out to reclaim the title from Dalian Boca Education & Technology Co. Ltd., which built a 197 module contraption in July 2016. This successful attempt made Maico set the record fourth time.
