Balls of steel or plastic welded and spun together at more than 10,000 RPM. Really cool!

Here's the deal: you go into a public place with a ban on smoking, and you light up a cigar. See how many puffs you can take before someone kicks you out! Now that's what I call fun! Use the search to see other crazy urban sports ;)

This is a really hilarious skit, from the guys at Balls of Steel! Like their previous work (The annoying devil, Bunny Boiler, Urban Sports) this one also doesn't disappoint. I know you'll laugh until your belly aches! Enjoy!

This is another clip from the UK TV show "Balls of Steel". This part is about a girl who hits on a guy right in front of his girlfriend. Needless to say that the result is hilarious. Cool

Another part of the UK TV show "Balls of Steel". This time a guy called Alex Zane tries to mess up peoples minds with two "games": a "lie detector" game and a spelling game. Useless to say that they're both very funny videos and worth wile watching. Have fun ;)

A rally car misses the photgrapher by inches. What's even more amazing, is the fact that the guy stood still, and didn't even try to make a run for it. He sat there as if he new the car wouldn't crash the concrete fence. Anyway...dramatic! Enjoy!

Well, in theory, massive amounts. Finding a way to store it, is still the biggest problem. But to properly visualize what a tiny amount of the energy that the Sun gives to Earth can do, here's a demonstration of a solar furnace melting a piece of steel in seconds. Now that's impressive!

This little Asus LCD monitor is put to the test with some extreme tools: a nail and hammer and most important: a crossbow with steel tip bolts It's simply amazing. Have a look!

Thanks to special steel plates, the University of Utah is implementing a computer that makes use of terahertz radiation instead of electricity It will be the first computer powered by infrared rays rather than electricity, a super-computer capable of operating at terahertz radiation (far-infrared), the only still unexplored frontier in the electromagnetic spectrum. It is being developed by a group of scientists at the University of Utah. It will probably require ten years of work to be completed. Currently, the group of scientists are making waveguides, the appropriate "channels" that will convey radiation and transmit it from one point to another. To mark a decisive step forward in research, the good results obtained by the use of special sheets of perforated stainless steel which are proving able to lead effectively terahertz radiation (the portion of the electromagnetic spectrum that is between microwaves and infrared, and whose wavelength is between 1 mm and 100 micrometers). As described in the study of Ajay Nahata (which will be published in Optics Express Friday April 18), these sheets will be "the matrix" on which to build the future of computer circuits. According to the surveys conducted so far, in fact, the number of perforations - arranged on a semi-regular on laminate - would maintain control over radiation, not disperse them over the surface of the material. There is still much to be found, for example, the way to drive rays, making them bend, split and reunited later.
