Physics and Science Concepts
Conservation of linear momentum
Operation
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.
Safety
Align the balls for the best results. Do not allow the strings to tangle.

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.
