Live With Kelly & Michael – Rube Goldberg Machine

This Science/4th of July themed Rube Goldberg Machine chain reaction device took 2 weeks of building and testing. The hardest part (aside from getting it to consistently work) was nailing in over 1,000 nails for the marble drop section. You can’t go wrong in a demonstration that uses chemical reactions, high voltage electricity, an Einstein doll, flammable gases, and a confetti cannon.
