Cardboard Bicycle Helmet Safer

Student designer Anirudha Surabhi has invented a bike helmet, called Kranium, that protects your head with cardboard. According to Wired, it

absorbs four times more impact energy that the polystyrene equivalent, and — unlike regular helmets which break on impact — it survives longer. One Kranium was smashed five times in a row and still passed the British Standard (EN 1078) test.
