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.

Small Tesla Coil Demonstration
Single-tube self-excited Tesla coil, 12v power supply.
Can burn paper, can smoke.
Package Accessories: Tesla coil, a 12V1A power supply, an electronic glow tube
The Tesla Coil, an invention of Nicolai Tesla in 1891, is also called an electrical resonant transformer circuit that can produce high frequency alternating current electricity with very high voltages at low currents. Tesla Coils consist of two coils (primary and secondary), each with their own capacitor which act similarly to batteries, storing energy. The two coils are connected by a spark gap. When electricity enters the system through an outside power source, the primary coils capacitor saves the incoming energy until its capacity is reached, then the current streams into the primary coil. Once all the energy has left the capacitor, the current is being pushed through the spark gap (a gap of air between two electrodes) into the secondary coil. The two coils will then pass the energy back and forth. At the top of the coil, a top-load capacitor concentrates the current and eventually can produce ‘lightning’ – a visual representation of energy! While Tesla coils today do not serve any other purpose than to be an educational tool to demonstrate scientific principles, a version of the coils is still being used in certain devices.
The device can be used to demonstrate scientific principles, such as:
– Current
– Energy Transfers
– Resonance and more!

Tippe Tops
These one-of-a-kind tops, called Tippe Tops, have a smooth, mushroom-like shape. The tops will right themselves when pushed onto their sides. When spun, they will rotate and slowly turn themselves upside down to spin onto their ‘stems,’ due to their offset centers of mass. This seemingly simple ‘toy’ packs a big scientific punch; use it to explain concepts such as moment of inertia, angular momentum, rotational force, gravity, and friction.

Bernoulli Bag, Green, Pk/4
How many breaths does it take to fill up an 8 ft long plastic tube? JUST ONE! Explore Bernoulli’s principle of air pressure with this long plastic bag. If you place it firmly to your mouth (like a balloon), it will take many breaths to blow it up. But if you hold it out in front of your mouth and blow, air pressure in the stream you produce is reduced, entrapping surrounding air to join in, filling up the bag. You can blow it up with a single breath! This is especially effective after your students have counted many of their own breaths in attempts to fill up the bag!

Resonance Bowl (Chinese Spouting Bowl)
The Chinese Spouting Bowl first appeared in the Han Dynasty (202 BC-AD 9). 4 “Han” dragons can be seen in the bottom of the basin, spraying streams of water up the sides of the bowl. It is said that the bowl was a kind of plaything for nobles, gifted scholars, and socialites in the Ming Dynasty. It was believed to foster happiness, prolong life, and increase strength.
Use the Resonance Bowl to demonstrate the behavior of waves and their interactions. Vibrations made by rubbing the bowl’s handles causes the water surface to ripple around the rim. Soon, water drops shoot up, quickly becoming continuous streams like tiny fountain jets. The water droplets and jets grow and diminish with each rub of the handles. It is believed to generate the precise frequencies needed to produce standing waves and the spouts of water rise from these waves.
