The answer you are looking for lies in the next video and is more high-tech than you might think! It actually uses a special kind of laser that gets absorbed by the dark colored balloon. Cool! Enjoy!

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

Here's a really interesting video on how to make a 245mW laser using nothing else than a DVD burner, and a flashlight. At 245mW it can light matches and pop balloons pretty easy, so be careful if you decide to do it at home!

Who would've thought shampoo could me so much fun? Scientists of the University of Twente made a video of leaping shampoo. This is actually a fluid effect called Kaye effect. Some fluids in motion can manifest this interesting effect. I don't know about the practical applications of it, but it's very beautiful! Enjoy!

Recipe: You take one portable RPL-300 Green Laser (around 316mW power output) and then you inflate 20 balloons or so until you start getting dizzy or bored (whichever comes first). You put the 20 balloons in a row, in front of the laser. The result is clearly visible in this video! P.S: As an alternative you can replace it with a several MW laser, add a tracking system to it, and call it an anti-rocket shield!

Did you think that you're having a bad day? If so, remember Murphy said that it can get a lot worst. Just watch this guy having a REALLY bad day in the office!

One of the most painful pranks you can probably think of. The dog is keen on catching the laser light. Guess where this dude puts it? Ouch!

Here's a new and very cool application of technology: letting your child draw on a wall without actual paint, but with lasers. It's quite cool actually, and very good for developing his creativity. Have a look for yourself!

This is the Skyguard Laser Defense system, which is part of the missile defense system, able to track, and fire upon incoming air threats. In this video clip the Skyguard Laser Defense System is tested by destroying mortars, artillery fire and missiles launched from the ground. The Skyguard Laser Defense system is definitely the future in terms of the missile defense system which America is believed to have up-and-running.

The transfer of data will be hundred of times faster than that by radio waves. The promise is made by the first tests conducted by a German institute. Receiving images in Google Earth or photos of the Hubble telescope in real time may soon be reality. A German institute has experienced a communication system based on lasers which will transfer data at a rate one hundred times higher than that possible with radio waves. The technology was developed by researchers from the Fraunhofer Institute for Laser Technology in Aachen on the company's Tesat GmbH & Co. under a project funded by the German Aerospace Center (Dlr).

Particles in a confined microscopic space, move in a coordinated manner and can be manipulated and observed with a precision never achieved. A nano-trap can be imagined as a tube the size of a billionth of a meter in which electrons are closed to study their behavior. Thus, scientists from the centers of the Italian Institute for physics of matter of Cnr "S3", Modena and "Nest" of Pisa in collaboration with Columbia University in New York, were able to observe with great precision the behavior of a quartet of electrons confined in one of these structures. Result: the particles move in a coordinated manner and with precise frequencies and can be manipulated. The study was published in Nature Phisics. As it is known, the physics of the matter the size of an atom or less follows different laws than those of classical physics. According to these principles, which fall in quantum physics, the behavior of particles such as electrons can not be described as we are used to (for larger bjects),but it is outlined mainly in terms of probabilistic forecasts. The technique developed by Cnr made it possible to determine the frequency of vibrations of particles through the use of a beam of laser light. The electrons in a nano-trap can only move in a coordinated manner and in accordance with the laws of quantum mechanics, vibrate at frequencies well defined that, thanks to this method, was possible to measure with unprecedented precision.

Filming particles is now possible. It was done for the first time by a group of Swedish researchers using extremely short pulses of light Getting images of electrons that do not appear to "move" has been impossible because of the speed of these microscopic particles. But a group of researchers in the Faculty of Engineering at the University of Lund (Sweden) now has found a way to shoot the movement of an electron using an innovative technique that provides for the use of flash light of extremely short duration.
