Last night I was working on the detailed sketch for the egg cracking Rube Goldberg. Here is the sketch. Note that all the materials are includes and labeled. Sketch of Olivia and JackM: The Machine has Eight steps: a hand hittting the jenga blocks, Jenga blocks hitting the ball, the ball rolls down the ramp and into some more jenga blocks, then the blocks hit a car which hite another car, in which that hits more jenga blocks and then the egg rolls in to the bowl.
