Just in case you were still being fooled into thinking that the TSA is good for, well, anything, follow along with You Tube contributor Terminal Cornucopia as he constructs a home-made "FRAGGuccino" from stuff you can buy from airport terminal kiosks—you know the ones you can enter after passing through security.
With just a stainless steel coffee mug, a Li-ion AA battery, some Axe Body Spray, a condom, and a bottle of water, Terminal Cornucopia was able to construct and successfully detonate an improvised frag grenade. Essentially the water filled condom breaks upon being thrown which shorts the battery, generating enough heat to ignite the can of Axe which transforms the mug into a flurry of shrapnel. Obviously, this was simply a test demonstrating a proof of concept but the fact that it can be done—apparently very easily, very quickly, and for less than $30. Get ready for your airport security screening to get a lot less pleasant. [Boing Boing]
