Ferrofluid, by definition, is a fluid that contains a magnetic suspension. We have posted them sculptures and videos with them before, but to most people, the idea of ever being able to play with the stuff seemed unlikely. Well, guess what? You can make your own ferrofluid, and do all the playing and experimenting with it that you want.
Heck, maybe you will even end up making a scultpture with the stuff that we will feature one day on this site. Life is insane like that. You never know.
This clip is taken from the Household Hacker YouTube page, and if you have a second today, go check it out. They even teach how you to make a keg out of a watermelon. Yes, you read that correctly. Life hacks are a beautiful thing.
