Welcome to Joe Genius - the first show that proves how exciting, hilarious, and sometimes dangerous, homegrown science can be. Each week Joe Genius will turn the spotlight on some of the best science videos online, from dry ice bombs to robot musicians, and explain why they work...or more often than not, why they don't.
