Bryce creates a spool racer according to these steps. Which step creates potential energy?
Steps:
1) Unwind the thread.
2) Insert a rubber band through the spool.
3) Put a toothpick in one end and cover it with tape.
4) Put a washer and pencil on the other end.
5) Wind the pencil.
6) Watch it roll!
Step 5- Wind the pencil
