So my brother had a birthday party the other day where this company that rents laser tag guns comes over and all his friends played a big game of laser tag outside. the guns worked surprisingly well, and there was even a "grenade" that would shoot lasers out in all directions once a pin was pulled. They were most likely IR lasers since I could not see a little dot on my hand when I shot myself, but the question is: I was surprised by how well the guns worked, despite solar interference; and I didn't know why so naturally I had to learn. Also, on a rant, would a "blue-ray laser gun" (blue laser) work better outside than a normal red or IR one? Because based on what science teacher said, blue light gets caught up in the atmosphere (turning it blue) and never makes it to earth, so my idea was that since there is no alien blue light coming to interfere, the game would work much smoother. Or am I getting this all wrong and red light DOES interfere with blue light. (actually, red and blue make purple...) ughh.. I dont even know what I'm saying anymore. Ill post now to get answers more quickly.
