Product Features

  • Alien 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.
