Introduction: 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.

Step 1: Wrap Up

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

Step 2: Wrap It Pt.2

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.

Step 3: Roll

roll it up

Step 4: Singe 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.

Step 5: Wala...whala..wa...youre Done.

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

Won't the plastic wrap diffuse the laser?

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

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!
