Alien Ping-Pong Ball
warning WARNING: CHOKING HAZARD-Small Parts. Not For children under 3yrs.
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.

Isaac Newton In The Dark
OK, glass with blue LEDs, but still. This is a Newton’s Cradle, always seen with steel ball bearings, but this time with frosted glass balls glowing a stunning bright blue while they swing on wires and prove Newton’s Third Law, and if you have to look that up you shouldn’t be reading this catalog in the first place. Just kidding--it says that for every action there is an equal and opposite reaction. You knew that. Newton would have ordered multiples of this beauty for all of his friends. Measures 7-3/4" tall on a 7" x 6" base with the standard (5) globes. You add (6) “AA” batteries for the glow.
$39.95 EACH
Hacky Joke
Kick around Batman’s favorite nemesis and improve your footy skills. In green, purple and white woven whatever, this Joker-face hacky sack is 2-5/8” dia. Hecho in Guatemala, where they don’t like the Joker either. You’ll get (2) sacks--one for each foot.
$3.95 PKG (2)
