A magnet placed just below a dish containing ferrofluid generates an array of spikes in the fluid. The magnetic attraction is strong enough to hold a magnet in place and to prevent the "fluid" from escaping when the dish is tipped. When the magnet is removed the spikes disappear and the fluid may be poured.

In order to properly present the sound and the flash of the piezoelectric device these movies are provided at 30 frames per second. Insufficient network bandwidth and other variables may result in dropped frames. If you do not see the flash when you hear the sound, you might replay the movie or use the scrub control to locate the flash.

Yellow powdered sulfur is heated until it becomes molten and brown. At first it flows freely, but then it becomes very viscous. Upon further heating, the viscous sulfur flows freely again and ignites. The burning liquid sulfur is poured into a beaker of water. When removed from the water, the sulfur is rubbery and flexible.
