Density Ball
Use this ball to demonstrate the effect of temperature on the density of a liquid. It consists of a copper ball about 2.25″ (57 mm) Dia., properly loaded so that its density is less than that of water, so it floats. When the water is heated, its density reduces and the ball sinks.

Rattleback, Plastic, Blue Color, Pk/10 (with Teacher’s Guide)
The Rattleback is a long, thin, half-elliptical shape formed in plastic. It has a slightly offset center of gravity, which causes the Rattleback to spin in a directional rotation of choice, usually counterclockwise. If you attempt to spin the Rattleback in the clockwise direction, strong preference will cause the Rattleback to “rattle” back and forth after few rotations, stopping and then reversing the rotation back to the preferred counterclockwise direction. The directional preference is so strong that if the Rattleback is at a standstill and you push down on 1 end, it will begin turning.

Ferrofluid Magnetic Display
Ferrofluid is the astonishing liquid that becomes highly magnetized in the presence of a magnetic field. Comprised of nano-scale magnetic particles suspended in a transparent liquid, undisturbed Ferrofluid forms into a smooth pool. But when a magnet is brought close, Ferrofluid reacts in strange and fascinating ways. With Ferrofluid in a bottle, you can safely and easily play with this spectacular substance. Using 2 included neodymium magnets, you can spike, toss, drop, pull, and bridge the Ferrofluid. You can even make it dance.
