Managing people will be so much easier with this giant red NO! button on your desk, or at home. Push it and hear a digital voice deliver (10) different versions of no, including No!; No, No, No; Noooooo; For the last time, NO!; and more. Great for denying tasks at work, and later-bedtime requests at home. (Remember--you can always change your mind to Yes, but going the other way never works.) Measures 3-1/2" dia x 1-1/2" tall in red with a black frame. You add a pair of "AAA" batteries.

Check out our keychain version! Same great sounds in a mini version. 

Our each is approx 1-1/3 oz (40ml) of The Original Slime (“Feels Wet and Cold!”) and it must be scientific because it comes in a cool little Erlenmeyer flask, although with a very un-Erlenmeyerish but important screw cap. We’ll pick a nauseating color. Non-toxic, for ages 5 and up, because you’re never too old for slime.

Based on drawings from Da Vinci's Codex Atlanticus, this Pathfinders catapult kit uses a pair of bent wooden arms as springs to launch clay balls (included) over (4) meters at enemy fortifications (not included, go make your own enemies). The assembled model will be approx 9" tall on a 10" x 7-1/4" base. Made from pre-cut, untreated wood from sustainable forests, and built with pegs for added strength and verisimilitude. A 2013 Creative Child Magazine Top Toy of the Year Winner and a great resource for STEM activities. For ages 12 and up.

Or the Swanee whistle. Whatever you call it, this little slide whistle (just consider it the smallest trombone in the universe) has an outsized musical history. No elevator has ever fallen in a cartoon without its accompaniment, and no jug band is complete without one, but Louis Armstrong also played one on his Hot Five recordings, and Ravel even required one in an opera score. In assorted plastic colors with a steel slide, 6-7/8" long x 1/2" dia.

And more. This accessory kit for smart phones (works with iPhone, Samsung, HTC, iPad, tablets and many others) has a 2” long clip-on bracket with screw-in macro, wide-angle and fish-eye lenses. Paul loves his kit and he’s our optics expert. Use the macro for insects, coins and diamonds. Fish-eye and wide-angle for great visual effects. Includes a little pouch to carry it all in, and tiny lens caps.

Note: Two lenses come threaded together to conserve space. 

There's optical science and high school physics, and then there's making pretty colors with this little 4-1/2" x about 1" acrylic prism. It makes the same rainbows that the beveled edges on the glass in the French doors to your grandmother's living room used to make on the floor in the afternoon while she was making supper. If you had a grandmother with French doors with beveled glass, who made you supper. If not, you'd better buy this prism or you won't have anything to remember after she's gone.

Ten furlongs are condensed to (7) inches, with very small horses, in the Desktop Derby, a 6-horse straight track that lets you win money while you teach the children the evils of pari-mutuel betting. The electric track pulsates and moves the nags along at a pace of about 45 seconds per race, with heart-stopping lead changes. The best part is that they're un-handicapable: a different horse, in a different lane, seems to win every time. Measures 9-7/8" x 3-1/2" x 2" high and runs off (2) "AA" batteries, included. (Stable the horses in the base between races.)

Stick a coin on top of the fishy plate on this plastic coin bank and it triggers a Hiya Kitty inside to mew some cat noises, then peeks out and reaches out a paw to snatch the coin. The box, which is mysteriously made to look like an orange crate, measures 4-3/4" x 4" x 3-1/2". You’ll need to add a couple of “AA” batteries but that’s the standard price of kitten cuteness today.

Spin the ribbed 7" handle of this hand-powered prop between your palms, and watch it take off. (If it lands instead of flying off into the wild blue yonder, reverse the spin!) Neon handle, bright, metallic-flaked 8" propeller, and a lift so high we imprinted it with our logo - the airborne Jarvis. It's all plastic, and won't decapitate anyone, but it's still for 10-year-olds and up.

Go fly a kite. We highly recommend this rainbow-colored nylon parafoil version, measures 20" x 23" at its widest with a 14-foot tail (over three times longer than a tiger's) on a spindle with a couple hundred feet of string. Includes a carrying pouch, too, making it a very practical, portable parafoil.

Forget that the 6-3/4" long body is festooned with Latin phrases and old maps. The stones/beads/glass inside the tube would make designing windows in cathedrals a snap. And hey, that's good work if you can get it. A nice gift for Rosetta window fans, and a must for that special bishop in your life.

More fun than a canned ham, this flip-top storage tin has a train set inside, with a plastic steam engine, tender, boxcar and caboose, as well as a 12-piece track that forms a 10" x 22" oval. You add a "AA" battery and you're the engineer. 

You don’t have to put your lips together and blow. You could just send us the price of a banana-chocolate smoothie and we’ll stick this pair of excellent wooden whistles in the mail. One is a 7-3/8” long, two-tone train whistle, and the other is a 5-3/4” long cartoony slide whistle that makes the dropping/sliding sound of your Saturday morning youth. No animator, jug band, life of the party or primary grade teacher should be without these.

Managing people will be so much easier with this pocket sized red NO! button on your keychain. Push it and hear a digital voice deliver (10) different versions of no, including No!; No, No, No; Noooooo; For the last time, NO!; and more. Great for denying tasks at work, and later-bedtime requests at home. (Remember--you can always change your mind to Yes, but going the other way never works.) Measures 1-3/4"" dia. x 1" tall in red with a black frame. Batteries included!

2" flywheel in well made metal frame. The trick is the same as it has been for 100 years. Wind the string through the spindle, pull it firmly to set the flywheel spinning, and perform effortless balancing magic on pencil tips, string tightropes, and the like. We tend to forget that bicycles and aircraft navigation both rely heavily on gyroscopic principles. It's never too early to tell the kids. Besides, it's fun.

About 30-40 highly polished stones, all shiny, translucent, or brightly colored, ranging from 3/4" long to 1/8" long. Great for mosaics, jewelry, or aquariums.

Our each is a dozen glass gems, in a round cut in (12) different colors, including pink, green, blue, red, golden, white, and various shades of each. Think diamond, ruby, sapphire, emerald, amethyst, topaz, whatever. In a dark blue book-like presentation box, the Liz Taylor collection features (12) gems at 40mm across (1.57” or tad bigger than a silver dollar) by 27mm (1.06”) deep.

The magic putty with dyspepsia is back. OK, it's fart goop, but you still wouldn't want to go to middle school without it. You'll get about 2-1/4 oz (in a color we'll pick) inside a little round plastic container that's about 2-1/2" tall x 1-1/2" dia--a little bigger than an old film canister, or roughly the size of a shot glass. Put in a thumb; pull out a rude noise.
