Won't the plastic wrap diffuse the laser?

Wow, I have the same laser as you, did you get it from dealextreme?
Nice idea!

that is a really cool waterproof laser except is there any thing to make the laser stronger, strong enough to burn?

And If you want to make it even better, replace the standard switch with a reed switch, stick the laser in a small tube/pipe with one end sealed and a screw on cap with a window and rubber gasket on the other end, and use a small magnet to turn it on or off!
