How to Make a Laser Pointer Waterproof!

Wouldn't it be wicked if you're laser pointer was water proof it would make an awesome laser stretching across a pool.
You need a laser pointer, a stove, some cling wrap.

take the cling wrap and get a half fot by a half foot square.

put it in the middle and fold the ends in and try and keep one layer of wrap on the part wwhere the laser comes out.

roll it up

put the laser over a low flame to where there is little heat to sorta melt it and tighten it up but keep it away from the laser head so it doesnt burn through.

I have done this several times for cool swimin fun and if you wrapped it tight enough it will work perfectly!
