Description: Lasers are just getting stronger and stronger, but sometimes you want to lower the laser beam's power. For example when measuring beam divergence or setting up an optical system safely. In this video, I will test some of my viewers' suggestions for lowering a laser beam's power. Including using my favorite drink: cola! Will it work? Will it even be the best choice?
