Fun with Ferrofluid Liquid Magnets and Sulfur Hexafluoride

Taking a break from circuitry, we’re going to show you some outstanding chemistry hacks.Â� First, we have liquid magnets called ferrofluid (which you can buy on eBay or make your own).Â� Next, we have fantastic demonstrations of sulfur hexafluoride aka anti-helium. Basically, it makes your voice really deep and light objects can even float on top of it.
