Fun with Ferrofluid Liquid Magnets and Sulfur Hexafluoride



Taking a break from circuitry, we’re going to show you some outstanding chemistry hacks.  First, we have liquid magnets called ferrofluid (which you can buy on eBay or make your own).  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.
