Newtonian demonstrator for science teachers. Mindless play for the rest of us. These are shiny, nicely balanced, high-performance examples of the classic Newton's Cradle - a ball on one end of a row of (5) suspended, barely touching balls swings into the others, and the ball at the opposite end reacts to the collision. The 11/16" dia balls in the small version (all-metal frame 6-1/2" high x 4" x 4-1/4") will collide about 30 times. The 7/8" dia balls in the large version (metal frame 5-1/4" high x 4" x 6", with a wooden base) will collide about 100 times. Awesome. Even more awesome that we paid someone to count the bounces just for you! (Unpacking note: Less awesome if you just yank it out by the suspension lines and pull a couple of balls loose. Be gentle.)
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.
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.
You take the Moo Popper, an open-mouthed 6" tall rubber Holstein, stick one of the (6) 1-1/8" dia chartreuse (or grass-colored?) foam balls in its mouth, give its bovine belly a good squeeze and it expels the ball across the room. Harder you squeeze, farther it flies. Impressive ballistics, good clean fun and an educational look at dairy farming practices all at the same time. Sorry, no fully automatic cows are available.
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.
They are back in stock but they won't last long! It's called chaos, but kids don't need a kit to create that, do they? And it actually is used to create really fun controlled "perpetual motion" Marble Run-type devices. You (your kids will never displace you once they see this kit) assemble a frame of your choice and adorn it with sets of chutes, slides, funnels, catch baskets, trampolines... You name it. The new Chaos motor driven chain lifts a ball to the top of your construction and off it goes through whatever course(s) you have set up. It is really educational physics, and we guarantee hours of creative fun with this top quality, attractively packaged kit. The tower has a max height of 78" and a whopping 602 pieces! Everything you need is included. Ages 7 and up. Want to see it in action or Need help with your assembly?

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!
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.
Known as the Beaver Blaster, this is our first-ever pistol-grip tail-triggered rodent. Stick one of the foam balls in his mouth, pull back the tail to cock it, then smack the tail to fire. Not unlike our cow and unicorn poppers, but a major step up in ridiculosity. The spring-loaded orange beaver is 8” long and comes with (3) 1-1/4” foam balls that store in the pistol grip. Has an effective range of approx (15) feet, and has a cut-out target on the box. Get a pair for office beaver wars.
