I can't understand why somebody would go high up on the cliffs and jump from that using a boat (kayak in this case). Maybe they do have too much adrenaline, but I guess it would be spent better as a firefighter or as a soldier. Anyway the crash at 3:22 proves that kayaks were meant for water!

Not a real flash mob per se, as the one invented by the Japanese, but this will have to do. A bunch of normal dressed people in a plaza, suddenly start dancing to folk music. The result is pretty spectacular. Enjoy!

By using thumbtacks this guy managed to obtaind some stuningly cool hologram that are just scratched onto the surface. By using the sun as a tool, he showcases this achievement. Pretty cool! Enjoy!

I haven't seen anymore cool ping pong ball tricks in the past year, so this video is a breath of fresh air. A bunch of college students, with just too much free time on their hands decide to make this cool and amusing video. Let's watch and enjoy!

They've recreated some stuff using LEDs and sheep. Yes, sheep. If you've never seen fireworks imitations with sheep, then do not miss this video. Enjoy!

I've never listened to the Red Army Choir before, but I must say they make a hell of a good choir, not to mention the show they put on with those costumes and the lead singer. Anyway, enjoy the song!

What actually happens if you sit in front of a laboratory particle beam accelerator? Well, you can try and find out, but I would suggest to have a look at this video first, which graphically ilustrates what happens. Very insightful. Also, you should keep in mind that these kind of particles are seen regularly in space. An effective way of dealing with them (using electromagnets) has been proposed, but is still in research. Enjoy!

This little bugger, can hover using multiple jets. The idea is, that eventually it may be able to fight off incoming missiles by using kinetic energy alone. Probably, they'll run in front of the missile or something. They are cool!

A bunch of nerds students rigged their dorm lights to put on a good show. It's pretty cool actually! Enjoy!

A recreation of classical games using stop motion animation. The video is called "Game Over". It's certainly among the coolest stop motion animation videos I've seen in some time! Enjoy!

Probably not permanent though! Anyway, pretty cool idea in using a laser printer for tatoos! Enjoy!

This video shows the perfect way to spend the day: opening up beer bottles, and of course drinking them. Great vid! Enjoy!

Here's a cool Chinese (I think ) video. They try to sing a tune using an R/C car and a lot of bottles. The tune is far from perfect, but the initiative is commendable! Enjoy!

A cool idea: turning an ordinary wush kung-fu demonstration in something spectacular by using Star Wars style light sabers. The result is one of the coolest fighting vids! Enjoy!

One of nature's curiosities. This little plant, doesn't like to be touched. At all! When you do, the leaves, fold, like it's shy or something. Brilliant!

Not what you'd expect. It's a kind of history of warfare, told through different kinds of food. Really cool, but all this fighting made me hungry!

How does a waterfall fall in "reverse"? Well if you've got a strong wind, it could blow the water upwards, stopping the water from visually falling by dispersing it, or by blowing it back up from where it came. Pretty cool!

I've seen what Ubuntu managed to realize in the past years, and I must say I'm very excited about it. Even though it's missing decent and easy to use fake Raid support, I might try to install it. Compiz is one of the cool things I've heard great things in Ubuntu. Now, KDE 4.0 makes use of some of these effects adding a welcomed revival of the old user interface. Cool!

A cool dad, got the idea of dressing up him and his daughter as a "Big Daddy" and "little sister", and go trick-or-treat. It's probably the most brilliant costume idea I've heard this year. Cool!

You can make your very own glow in the dark mountain dew by using only baking soda and hydrogen peroxide (aka oxygenated water). The chemical reaction from this mix gives a pretty cool glow!
