Our Step List
1. A student pulls a string attached to a wood block via pulleys
2. The block raises and releases a large metal bearing
3. The bearing rolls down a ramp and moves a teeter totter
4a. The teeter totter's right side moves down and taps a golf ball
5a. The golf ball rolls down a wooden block stair case and lowers a cup attached to a pulley
6a. The lowering cup's motion raises a weight attached to the other end of the string
7a. The rising weight taps a wooden ramp
8a. The wooden ramp's dislodging releases a golf ball down the ramp
9a. The golf ball rolls into a cup, lowering it down via a pulley
10a. The lowering cup is attached to a pivoting lever via a pulley which pivots over, dumping milk into a bowl
4b. The teeter totter's left side moves up and taps a pivoting pipe containing a golf ball
5b. The pipe pivots over, releasing the golf ball which hits a metal ball bearing stored below
6b. The ball bearing rolls down a ramp and moves a cup positioned on a zip line
