Problem- Will if a ball hits another ball will they both go down a PVC pipe.

Materials- PVC pipe, two marbles, a domino, and a flat surface

Hypothesis- I think that they will both go down the tube because the force of the first marble will make the other marble go down the pipe and the so will the other one.

Procedure-
1. gather materials
2. get marble A
3. get marble B
4. put PVC pipe at a 45 degree angle
5. put the domino behind marble A
6. set marble B in front of the PVC pipe
7. hit the domino over and have the marble hit the other one and go down the PVC pipe
8. observe
9. repeat steps 1-8 at least three times and list yes if both balls went down the tube and noif they didn't
10. create graph
11. conclude
