Liquid Nitrogen Explosions w/ Ninja Kidz!

This weeks Challenge: BUILD YOUR OWN RUBE GOLDBERG MACHINE! If you did this challenge last year, you may already know that the Rube Goldberg challenge is all about complexity. Build a chain-reaction type machine that solves a new, simple problem in an overly complex way. This is the coolest part of being an engineer - if you want something to exist and it doesn't yet, you build it into existence. Free to watch on Dr.Doc Kids.
