Rube Goldberg #3

Our first attempt started with jenga blocks going to Aravs stairs. We learned quickly that it was hard to get the blocks to hit the right point and that we needed to make it shorter. Then we decided to start in the hall. That worked pretty well and we mover on to the next step. Next we wanted the jenga blocks to hit a ping pong ball which would go down the stairs and hit a race car. It was really hard to have the ball hit the car for two reasons. First the ball didn’t have enough force to make the car move. And second the ball never hit it perfectly. So we changed our design and thats where we are now.
