Control the back and forth of a super ball.
- super ball
- 10 sheets of paper
- 10 paper clips
- 10 rubber bands
- 20 feet of string
- masking tape
- ruler
- 2 tables
- Can you find a way to get a super ball to go from one table to another and then back to the first table?
- You can only use 10 sheets of paper, 10 paper clips, 10 rubber bands, 20 feet of string, some masking tape, and a ruler. You can't use your hands.
- Set the two tables so they are three meters apart.
- Think about what makes things move forward and what makes them move backward.

I tied the string around one leg of a card-table. Then I twisted paper clips around the legs of another table, making the string go around the table leg without touching it. Then I tied the rest of the string back to the 1st table. I also made a paper clip holder for the super ball. It was pretty easy, except for making the string not touch the leg of the second table.
