Who would have thought dropping some metal through some more metal could ever be interesting, but here you are watching this video just as mesmerized as I am.
Now to drop some science on ya:
When a magnet is dropped down into a metal tube, the magnetic field around the magnet is altered by the confines of the tube, which pushes electrons in the metal tube around in circular, ‘eddy-like’ currents. These eddy currents have their own magnetic field that in turn opposes the fall of the magnet. This makes the magnet fall slower than it would in a non-metallic tube.
Yeah! Science, B*tch!
Now, all I need is a giant copper pipe and a magnet suit (properly earthed, of course) and we’re in business.
