Grant and I started to work on our machine. We decided to work on it backwards so we started with the phone on a lever, then we did the box dominos and the ramp. We had a lot of trouble getting the car to hit the box in the right space. If we hit it too low it will fall backward. If we put the ramp too high the car won’t have enough speed to go up the ramp. So, what we did was we elevated the whole entire track until it was high up and it did have enough speed.
