Magnets and Marbles

This isn't your usual kinetic pachinko balls-in-a-gravity-maze toy, but a mindbending demonstration of magnets. It starts getting really crazy at about 2m in but one should enjoy the subtle pleasures too. Read the rest

Saturday Morning Science Experiment: Up With Magnets!

Ferrofluids are basically just iron nanoparticles suspended in a liquid. In the presence of magnets, they do some pretty cool things. For instance, ferrofluids flow to place where the magnetic flux--the strength of the magnetism--is strongest. So if you magnetize the screw from a meat grinder so the magnetic flux is denser at the top than it is at the bottom, the ferrofluid will climb the screw like staircase.
