Economical laser pointers are useful for many optical experiments. Lasers operate on a push-button switch, are housed in a rubberized aluminum pen-style case, and include a pocket clip.

For performing experiments in conservation, velocity, elastic collision, acceleration and momentum. The set contains two high impact plastic cars with snap in wheels and two spring steel bumpers with rubber stopper assemblies.
