Five balls of equal masses are suspended by strings and aligned in a row. The balls can be pulled back and made to collide to show the conservation of linear momentum.

PIRA Code(s): 
Set up time: 
1 minute
Physics and Science Concepts: 
Conservation of linear momentum
Pull back a number of balls and let them collide with the other balls, allowing the same number of balls to be released on the other side.
Align the balls for the best results. Do not allow the strings to tangle.
