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 £20. Get ready for your airport security screening to get a lot less pleasant. [Boing Boing]
