Rube Goldberg Cake Server

Joseph Herscher of Joseph's Machines designed a delightful and inventive chain-reaction sequence that serves him a piece of delicious pineapple upside-down cake. This one involves crashing electronics, a baby playing with a phone, and a candle that initiates motion by melting butter. The wheel that rolls over his head is a bonus. And the baby gets a piece of cake, too! The story behind the cake server is in a different video. (via Boing Boing)
