These lasers are alot of fun they actually appear to touch the stars. You have to avoid pointing them at airplanes because they can blind the pilots. Pilots have actually been issued special glasses to reduce the effects of the lasers on their eyes if theyre hit by one. This is a cheap one they have high dollar ones that can start fires and burn the skin. they have tips you can put on the beam and make laser light shows to but I think they were originally designed to point out constellations and stuff.
