…Condoms can waterproof electronics?

Dual Waterproof Firing Assembly

Apparently, with two clear condoms and a little wet suit glue, you can waterproof just about anything Navy SEAL style. The SEALs use this method to protect the firing assemblies on their underwater explosives (the result is called a Dual Waterproof Firing Assembly), but you can use it for much simpler tasks, like taking underwater photos or protecting your cell phone when you’re out boating. Plus, the look on the counter clerk’s face when you ask for “really clear condoms” should be good for a laugh or two.
