yell at me for using my trademark ability on this, but...

We may be able to glitch the lasers.

Think about it: Even if they are photon based (which I am guessing is what they are, since 99% of lasers are photon-based) they have to have some kind of opening for the photon energy to come out. And in order for the photon energy to come out, there has to be some kind of object inside that creates the energy. Shouldn't the water get onto this object, when electrified, and short it out? And if they get shorted out, then they can't shoot. And if they can't shoot, how are they going to kill us?
