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.
It's a toy! It's a scientific demonstration! Drop the 1" ball with a straw attached and watch the outer rocket straw launch. The farther you drop it, the higher the launch, which is the fun version of Newton's Third Law of Motion. And we give you (2) rocket straws on account of we know you're going to lose one.
Perfectly suitable for all your non-professional ping-pong-ball applications. These guys are white-ish, with a visible seam, and are 37mm in dia, as opposed to the standard 40mm or the former standard 38mm professional ping-pong balls. Priced so you can buy enough to do any number of clever things with them.
Despite parental advice, here's a good reason to sit in in a dark room and think small. This Plasma Storm isn't as large as a standard plasma ball, so not only is it much more affordable -- the effect is concentrated and startling. The black plastic base has a switch. Turn it on at which point the 3" dia plastic globe (think baseball size) is filled with blue stems that flare to pink, looking like dozens of electric flowers searching for a way out. Very cool. Comes with a 6-ft power cord with transformer.
Together again and not available in any store we've ever heard of. Our party favors set includes an improbable 2" dia squishy egg with yolk, a similarly sized squooshy tomato, a 3" long high-top gym shoe-key chain, and a nice set of joke partially rotted upper teeth. Add the world's smallest ping-pong set, including (3) standardish balls, (2) tiny paddles and a mini-net for our deluxe set! Just try to find them anyplace else for our price!
Our clear glass vials come in 5ml, 10ml and 20ml sizes. You pick. The 5ml vials are 1-9/16" tall x 7/8" dia with 1/2" ID mouths; the 10ml vials are 2" tall x 15/16" dia with 1/2" ID mouths; and the 20ml vials are 2-3/8" tall x 1-1/8" dia with 1/2" ID mouths. All will take a #3 cork (our 88748), which is sold separately.
Golf, without all that exercise and fresh air. Three cool green dice
with traditional white spots, plus a fourth die with game shots, like
Out of Bounds. One or two players keep score on the small, reusable game
board. Barring any interest in golf, you can still stay out of the sun
and find some desultory game to play with the dice.
