Fidget Spinner
These handheld spinning devices feature high-quality bearings at the center for a
long, smooth spin. Use these spinners to study gyroscopic motion, forces and kinetic
energy or just use them as a fun way to de-stress!
Catalog No. Description Price/Each
AP9568 Fidget Spinner $10.35
Hand Boiler
Amaze your students by having liquid boil with the touch of your hand. You can even
perform a fractional distillation (instructions included).

Magnetic Spin Wheel
The perfect “toy” to teach concepts of resonance. Tilt the wand from side to side
and watch as the wheel spins faster and faster. Students will become resonance
enthusiasts as they attempt to get the wheel spinning as fast as possible. Relate the
motion to that of a swing, or to the Tacoma Narrows suspension bridge collapse. This
versatile toy can also be used to demonstrate concepts such as energy, momentum,
and rotational motion.

The Two-Potato Clock
Operate a clock for months at a time using nothing but two potatoes as an energy
source. Or you can try limes, lemons, plants, soda and more. Besides providing you
with a clock that keeps great time, we also explain the chemistry of how and why
the Potato Clock works. Fun!

Make Your Own Soap Bubble Solution
A simple solution for making soap bubbles can easily be prepared in the home or
laboratory. To make one liter of soap bubble solution, mix 100 mL of Dawn® or Joy® dishwashing
liquid with 50 mL of glycerin. Add this to 850 mL of distilled water. The mixture
should be stirred, not shaken, otherwise excessive amounts of suds will be produced.
For producing large, long-lasting soap bubbles, increase the amount of the detergent
to 200 mL, the glycerin to 100 mL, and then add to 700 mL of distilled water.
Again, stir the solution. You may have to experiment with your soap mixture to get
very large bubbles.
Distilled or deionized water is important to prevent interference from dissolved
metal ions. If the solution does not seem to work well, let it sit for a few days to a
week. Aging seems to improve the characteristics of soap solutions.
The bubbles break with a fair amount of force; keep them away from your face.
Also, a floor wet from a lot of broken bubbles will be very slippery. Be careful to avoid
falling. With a group or class, it is best to work with these solutions outdoors.
Pulse Glass
Dramatic demonstration with only the heat from your hand. Two glass bulbs are
connected with a glass tube and contain a colored, volatile liquid. Holding one of
the bulbs in your hand causes the liquid to boil and the vapor to move into the other
bulb where it bubbles rapidly. Caution: Never use with any heat source warmer than
body temperature.
