Mr. McKeown happens to be the owner of Plymouth Karting, where he used this technical know how to stabilize the trolley through the use of go-kart wheels. His record breaking feat did not exactly shatter the previous one, edging it out a wee bit compared to the past 42mph (67km/h) mark. Of course, it is not an official record, and McKeown’s ultimate goal would be to see his frankenstein of a shopping trolley achieve the 60mph (96km/h) mark. Good luck to McKeown in his future endeavors, and hopefully at 60mph, the shopping trolley would still be able to go in a straight line! What are some of the other zanier ideas do you think that you can strap a jet engine to and ride it down a race track?
