A cool video made by the military about the effect of a torpedo on an American destroyer. The torpedo doesn't actually hit the destroyer, but it detonates a few meters under it, causing a big void. When water surges to replace that void, the force it creates, splits the destroyer in half. A really cool and amazing video. Enjoy!

Well, the Russian Lada Niva might not be well known in the US, but in Europe it is infamous for its indestructibility. I've seen it pawn the military version of the Hummer on rough terrain. Yeah. It's a pretty amazing car. These guys modified to go underwater on the lake bed. It's simply amazing!

Here's a cool way to hunt for fish. Forget dynamite. You'll be gathering them up for a few days. No, really, this tests sometimes are mad, people got to think that other humans could be at the receiving end of that! In an artistic way though, it's very beautiful. Enjoy!

Researchers have made a fabric, made from polyester fibres which is coated with millions of small silicone filaments. This the most water-resistant clothing which was ever created by man. Because of the nanometre-scaled filaments, a coating which stops water particules from going through the coating to the polyester fibres which are underneath. This mixture between a hydrophobic surface and a nanostructure coating leads to a super-hydrophobic effect. This is similar to the surface of Lotus leaves. There are many applications for this: from stain resistant clothing (see video) to reducing water drag in submarines or swimmers. This could lead in a drag decrease of up to 20%. Here's a little video from the Today Show with a stain resistant shirt which usese nano-technology (Nano-Tex material).
