Rube Goldberg #5

So I went to Tyler’s house today. We finished!!!Here is our steps: STEP#1: We roll a baseball down a cardboard ramp. The ramp stops at sea-saw. STEP #2: Since the baseball stops at the sea-saw it tips it over and lets a tennis ball out. STEP #3:the ball knocks over a Jenga Tower. STEP #4: On the Jenga Tower is a tennis ball  which is attaced to a string. When the Jenga Tower falls the tennis ball is relased  and it swings. STEP#5:The swinging ball hits books stacked like dominos. STEP# 5: The books hit a toy truck. STEP #6: The truck falls down the ramp.  STEP #7: The truck pushes a car to go through a loop and the car hits a button which will charge a phone.
