Walking on eggshells is probably nothing for Li Guiwen of Beijing. After all, he has driven on beer bottles:
Li Guiwen, an army driver from Beijing, steered along 1,798 bottles for 60.19m in a time of eight minutes and 28 seconds in eastern China's Zhejiang province. [...]
Li, who thought of creating this record after a drinking bet with friends, added, "Since the failure last year, I have been training constantly."
