In 2009, over 1,100 people came, participated and watched as artist and renowned chain reaction creator Arthur Ganson led the 12th Annual Friday After Thanksgiving Chain Reaction. Teams from all over bring a link, which is then connected to the next link and becomes one giant contraption, set off at the magic moment by Ganson. Engineering principles, laws about motion and energy and all kinds of other science - including the natural world - pop up during the Friday After Thanksgiving Event at the MIT Museum, held in Rockwell Cage Gymnasium.
