Thumbing it

A Kavala martial arts enthusiast has sent a videotaped account of himself balancing on his thumbs on a moving car to the Guinness Book of World Records editors in the hope that his feat will qualify as an official world record. On Sunday, Costas Nikopoulos held his “thumbstand” on the roof of a car traveling at 20 kilometers per hour over a 70-meter stretch (20 meters further than he had originally intended).
