So, what happens if 42 metric tons of water are dropped from a giant excavator onto a car? The result is staggering! Enjoy!
The extreme test consists in dropping an egg from the top of a 22m (72ft) building. The shock absorbing gel awaits the egg at the bottom. This gel has been used for some time now in running shoes, to dampen the shocks. Really cool!
It's amazing how a simple reaction on earth, becomes so spectacular in space. The bubbles form, unite, and explode in a different way than you'd expect. Very cool! Enjoy!
Funny
Damn! This guy doesn't even wonder how he's going in, no matter going out. He literally drops into the store, and is unconscious for a few seconds. Watch him squirm in agony, and pain when trying to get out. Ouch!
A funny compilation of some practice air drops of the US military that didn't go exactly as planed. They're very funny if you don't start to count the repair costs
For those of you who didn't get to see this episode, here is the joke everyone (including CNN) has been talking about. I hope the guys at Youtube don't remove it as they did with other copies of this video. So, get it while it's still fresh!
This is a hilarious internet DSL commercial entitled "Log off". It shows how a neighborhood is transformed after sharing their internet connection. I hope you'll enjoy it as much as I did
WTF..?!
YouLickit!? Why? Why would you do that? Why would anyone want on his iPhone an application in which the main purpose is to likc stuff? The simple fact that someone has this application installed should drop the second hand price for that device in half. WTF?
Amazing
Slow motion imagery helps us understand the physics of things around us, and also makes for some incredible footage. For example, who knew what a small water drop does when it hits water? It's fantastic! Enjoy!
An amazing video caught on tape of a meteor dropping hard and fast to Earth. Now you can imagine what the dinosaurs saw before the big bang. Amazing footage! Enjoy!
I've got to tell you, that I didn't believe in this myth. The energy from the mobile phone is so little that, you aren't able to get a spark. Things change if the energy is "stored" in the crumpled aluminum foil, and making lots of calls. The only realistic scenario I can come up with is that your car or some other piece of metal is already statically charged and your phone is the water drop that fills the glass. Anyway, it's very unlikely!
In the 1960 America (and Russia) begun underground nuclear tests. Not only were they trying to see how the new nuclear bombs perform, but also they wanted to see if it was possible to shape the relief with the help of underground nuclear explosions. After a few tests, the idea was droped, but the video of this underground nuclear explosion remained. Enjoy!

Small robots that walk on water like insects? The kitchen table, the walls of a room or the arms of an armchair that are self-cleaning? Two phenomena that Xiao Cheng Zeng, a professor of chemistry at University of Nebraska in Lincoln (USA), considers possible in the near future, and based on the same characteristic: super hidrofobia.
Thanks to the computational performance of the super computer of the Riken Institute in Japan, the researcher is able to reproduce the conditions that give the area the property is to "roll" away the drops of water.
In nature this phenomenon is observed on the bristles of caterpillars or on lotus flowers, and allows insects that often are seen on ponds slip skate on water. As the authors of the study reported the caterpillars or insects skaters get the super hydrophobia surface through a "two-tier" surface which means a waxy base on which there are microscopic structures like hair, often covered in turn by smaller "hair".
These gradients decrease the surface area in contact with the drop of water. The result is that the drop rolls instead of sliding, as it would be a hydrophobic surface.
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).
