Yeah...here's the reason why they have this rule. A pretty good rule know that you think about it. But, what about medical metal parts(bolts, prosthesis, and so on)? What happens with them? Anyway, it's cool! Enjoy!

While filming out a window, a lightning bolt strikes a nearby tree. The slow motion reply shows the beauty of the lightning strike going through the tree. This is the reason why you shouldn't be caught under a tree during a storm. The researchers say that the safest place to be is...yes...your car! That's because you're in a Faraday cage!

WTF is wrong with these people? Are they mad? Or are they simply too nerdy to realize how lame what they are doing is. Lightning bolt...FTW Enjoy the circus!

Here's an astonishing homemade video capturing an airplane in mid flight which gets struck by lightning. Don't blink, or you'll miss it! he he.

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!

Although it may seem dangerous, it's literally the safest place you can be during a storm. Because it acts as a Faraday cage, and because it grounds the lighting immediately, this woman and her family lived to tell the tale!

A new advanced thermometer, based on noise Johnson, increased by five times the accuracy of current systems After seven years of work, researchers from the National Institute of Standards and Technology (Nist), the U.S. organization for the development of technologies, have managed to build a new type of thermometer, Johnson Noise Thermometer (Jnt), defined by the same scientists a goal of thermometry, which advances to five times the current state of the art. The new device will in fact take measurements of extreme precision, never obtained so far, fundamental for basic research and for the definition of units of measurement. At the head of the project is Sam Benz, the Quantum Devices Group, which officially presented it on June 9th at a conference on measures of accuracy in Broomfield, Colorado. The new thermometer provides the temperature starting from noise Johnson (hence the name), generated by the random motion of electrons inside a resistance. This measure is directly proportional to the temperature, and the system makes it possible to reduce the error without any additional calibrations. "All measurements are electrical, and do not require volumes of gas or mechanical systems that sometimes, depending on environmental conditions, could give approximate results." says Benz, " beauty is that the measurement is also very simple to perform.
