A Guinness World Record for Mainz physicists

12 June 2017

By constructing the longest magnetic ball accelerator in the world, Johannes Gutenberg University Mainz (JGU) has set a new official Guinness World RecordTM. A team of physicists, supported by high schoolers from two schools in Mainz, worked for months on the project. The Mainz Public Transport Authority even cleared one of its tram lines for the world record experiment. When the final ball crossed the finishing line, the Mainz physicists started celebrating with hundreds of visitors of all ages.
