Oil is a very precious natural resource; this video shows how oil is stored in a trap formed by tectonics forces.
Pyrolytcs graphite is a diamagnetic material, which means that a magnetic field will be repelled by this material. Thus the magnet floats
A simple science trick you can do at home, using two rubber bands and a CRT TV screen. The TV screen works as a stroboscopic light, and when the frequency of rubber band is near the TV vertical frequency the rubber band seems to moving in slow motion.
"A single seed crystal was added to the saturated sodium Acetate solution while at 30C. Omnidirectional needle-like crystals radiated outward from the seed on contact at the solution's surface."

"This is a demonstration called the rubber band heat engine. As the name suggests, you take rubber bands, apply heat to them and they do work for you... just not terribly much of it. But its interesting nonetheless."

Using some sugar, NaOH, and KMnO4 is easy to prepare a rainbow juice. The KMnO4 is reducing and changing the flask color.
This is a very useful invention that can help a lot, this mechanism may save some fingers stopping immediately the saw.
The creator of machine will test the efficiency of his invention, the saw will stop? See for your self

Slow-motion Rubber Band Trick: that is Amazing!
