Small scale models which levitate diamagnetic materials such as this haven't existed for the classroom, until now! It is only recently, with the creation of artificial neodymium magnets and artificial pyrolytic graphite, that the effects can finally be easily demonstrated.
Diamagnetism is a very interesting and promising phenomenon in which macroscopic objects can be made to float under their own [...]

The Sunset Egg is a fun and engaging demonstration on the science of light. The egg is made of “opalescent” glass. This refers to the way it looks different at different viewing angles (similar to the gem’s properties).
An oil-polished Sunset Egg, lit from below, shows both blue sky and yellow sun.
To use the egg [...]

Radiation is the transfer of thermal energy using electromangetic waves, which includes visible light, infrared radiation, ultraviolet radiation, x-rays and microwaves and radio waves. A camera flash is designed to give off a whole lot of visible light in a short amount of time. The black ink in the newspaper absorbs this radiation and increases [...]

Pencil lead and some batteries make a small plasma cutter that is used to etch a pattern in aluminum foil.
In this simple but cool demo, you are able to observe how a high velocity ionized gas (plasma) conducts electricity across a small gap between the tip of the pencil lead (graphite) and a conductive solid [...]

Welcome to our March 2015 Issue of our CoolStuff Newsletter. This month, we are featuring a simple, safe and Cool device called an Energy Stick. Physics teacher James Lincoln demonstrates several experiments that help students understand the principles of electric current and light. James has authored many of our past CoolStuff Newsletters, and teachers have [...]
