World Records: Speed

When most of us think of speeding, we remember that time we got a ticket for driving too fast. Breaking a land-speed record with a jet-engine-powered supercar is obviously not in the cards for the average joe. But when you check out this quiz, you'll realize you don't need to be an Air Force pilot or a professional athlete to set a world record. You can build your own motorized love seat and speed it across a bridge! Or run a marathon -- backwards! Get inspired, people!
