What if you could bottle a black hole? Let's use magnets to create the illusion of one of space's greatest secrets! This cool and creepy illusion is all thanks to ferrofluid. It's made up of really tiny pieces of iron suspended in a liquid. Those iron particles are really attracted to magnets, so if you bring one close, the particles and the fluid will move with it! *Ferrofluid tends to be very messy, toxic if ingested, and irritating on sensitive skin, so be sure to use gloves when handling ferrofluid and have a grown up supervise.
