Physics of a Diamagnetic Hover Board [W/Video]
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 [...]
Simple Model of How the Sky Changes Color at Sunset
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 [...]
