A Canadian man who lost an eye in an accident has installed a tiny wireless camera in the empty socket.

From neurones to neutrophils, liver cells and islets, T cells and skin cells, whole maggots and drosophila embryos, they all dance…

Rubbing the rim of a wine glass with a wet finger will cause it to resonate at its resonant frequency. The glass is placed in front of a speaker playing a sine wave, created by the function generator, of this same frequency. When the amplitude is turned up, we can see by shining a strobe light at the glass that this resonant frequency causes it to oscillate. When the glass becomes too stressed, it will shatter, which we see very clearly on high speed video.

Now this dog is really having a good time. Look at it’s tail wagging.

In the electric field of a Van de Graaff generator, an unprotected Ben Franklin feels electrostatic forces. However, when a metal cage surrounds him, he is completely shielded against any electricity or electrostatic force. This is due to the fact that all charges in a conductor reside on the outer surface, and always rearrange themselves to cancel out the electric field in the interior.

Now this is one cool invention.
