A Dutch engineer built a car controlled by a goldfish swimming inside a water tank; earning a Guinness World Records title

A goldfish swimming inside a water tank has earned a Guinness World Records title after steering a motorised vehicle for 12.28 metres in just one minute. The unusual invention was created by Dutch computer engineer Thomas de Wolf, whose pet goldfish, Blub, became the unlikely driver of a motion-sensing car that translates the fish’s movements into directions for its wheels. According to Guinness World Records (GWR), Blub and de Wolf achieved the record for the greatest distance covered in a motion-sensing vehicle by a goldfish in one minute. The attempt took place on the set of Italian television programme Lo Show dei Record in Milan on January 23, 2025, with the achievement reported publicly by Guinness in March 2026. Blub covered 12.28 metres (40 feet and 3.46 inches), comfortably exceeding the minimum distance of five metres required for the record.The vehicle was presented during the programme hosted by Gerry Scotti, with Guinness adjudicator Sofia Greenacre overseeing the attempt. After the record was confirmed, de Wolf received an official certificate and medal alongside his aquatic companion.How does a goldfish drive a car?The invention works through a motion-sensing camera ...
