Week in Geek, weird nature edition

This video might look fake, but it's only exploiting capillary action and magnetism. Watch it first, then read on.

The big black ball at the center is a magnet and the black fluid is just a ferrofluid, i.e., a liquid that becomes magnetized in the presence of a magnetic field. More specifically, the liquid itself is made up of magnetic nanoparticles suspended in a solution. The action in the video comes from the ferrofluid being added to the bubbles away from the central magnet which then draws the fluid towards it through capillary action where the bubbles intersect. The orange color is just normal dye adding to the fun, because why let black have all the fun?

Speaking of fun, more geek for your week:

Geek you later. @Summer_Ash
