Minute Earth explains what is best to wear and to do during lightning storms.
Most people have heard the safety tip that the car is a safe place to survive a lightning storm because it rides on rubber tires, but ironically it is the metal body of the car that protects you from the high voltage.
As Minute Earth explains in this new science video, metal is such a good conductor of electricity that the electrons merely glide on the surface of the metal, keeping anyone or anything inside the metal fairly safe.
This concept is actually applied in real life as linemen working on high voltage wires wear literal suits of metal to help protect them in case of an accident.
Most of us spend more time inside than we ought to, whether we are busy with work or activities at home, and that can have a significant impact on our health. ASAPScience looks at the health ramifications of spending too much time inside.
If you spend most of your day inside, this is for you!
Free Falling In Outer Space
Have you ever wanted to float in space like an astronaut? It turns out that it’s less like floating, and more like a free-fall in orbit around the Earth.
Enjoy!
If you were to orbit the Earth, you’d experience the feeling of free fall, not unlike what your stomach feels before a big dive on a roller coaster. With a little help from Sir Isaac Newton, Matt J. Carlson explains the basic forces acting on an astronaut and why you probably shouldn’t try this one at home.
