Alien
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
This sinister device seems at first glance to be an innocent ping-pong ball. Touch both of the metal strips on the weighted bottom, however, and a circuit closes, making the ball flash red and moan eerie electronic sounds. Can be used to illustrate the idea of an electric circuit to children-show how electricity can flow through a chain of people holding hands, or that a little dampness can improve conductivity, et cetera. Powered with two watch batteries (included) so there is no danger of shock.
