Science Chain Reaction .
Participants can create their own chain reaction out of materials lying around the house.
It can be as simple as books falling against one another or as complicated as a Rube Goldberg invention. For example, imagine a ball rolling down a track that lands on a board that tips a book that falls onto a string that pulls six precariously balanced blocks. Bring your own chain reaction, or just come and watch, or perhaps help the creators link their chain reactions. Participants range from Girl Scout troups to artists and scientists, from MIT clubs and living groups to family teams. Bring your creation to the museum at 1pm on November 24 and connect your device to others to make one grand chain reaction.
