A very cool new invention is the motorcycle airbag. I've seen it before but never in a real test. It works by strapping a cord between you and the motorcycle. When that cord is tensioned, it can pull on a CO2 canister, which quickly inflates your airbag. It's really cool, and a potential life saver!

Yeah, like that was gonna stop him from being in serious pain. I really enjoyed watching this! Stupid!

The funny thing about all of this is that the driver actually survived. That just goes to show you how far you can go with safety roll cage, a 6 point harness, special Recaro driving seats with lateral support, and a racing helmet. Yes...you can literally fall off a mountain with it! Just watch!

An amazing material was developed by Chinese scientists which is composed of carbon nanotube films and has a possible application (among otther) to produce the world's thinnest speakers. Nanotubes, are a new carbon breed of material, which is 1000 times smaller than the width of a hair and can give sound with the "same quality of conventional speakers". This, however, does not require magnets of any sort or moving parts for that matter at all. You can easilly imagine speakers everywhere: on walls, helmets, thinner ear plugs or even on your shirt. This is possible because very thin carbon nanotube films, with the right frequency of electric currents, can emit sound. It also has a wide frequency response range and high sound pressure. It also turns out that they are practical to build, and are even stretchable. Here is a video with the actual speackers embedded in a flag!
