well interesting fact of the day....from physics...
Two light can make a dark
Two light wavelengths are added together...and each cancels the other, creating dark. Pretty cool stuff.

so if i shine two flashlights on each other, they are dark? Um no. Not in that case, maybe you should expand a bit more, sounds really cool. Did you actually try it or just learn it???  |

learned it and saw it in a demo...
flashlight won't work because the light wavelength isn't concentrated enough. There will be too much interference. laser pointers do work.
