Car pops this (balloon)
Selina, Mista
The Rube Goldberg machine starts with the ball on the lever (gravitational en.). The ball rolls and hits jenga blocks which start falling (gravitational en.) and the blocks push the car down the inclined plane (potential en. transfer to gravitational en.). At the bottom the car goes through the gate and pops the balloon (gravitational en. transfer to sound and elastic en.).
