Zivko the Robot is back in stock! Our best selling STEM kit ever! Just call her (or him--it’s unclear and we don’t like to ask) “Zivko” because “the Robot” is her last name. Using just a screwdriver and side cutters, you build Zivko from this 107-piece S.T.E.M. kit. Set the mode for “Follow Me” or “Explore,” and Zivko will, yes, track you, or evade obstacles, respectively, via an infrared sensor and micro-controller programming. Interactive LEDs and sounds abound. Measures approx 5" x 5-1/2" x 6-1/2" when assembled with all (6) legs. You add (4) “AAA”s for power, which is the least you can do for someone this cute. Ages 10+.

And we say that with a history of silly that’s virtually unmatched. You slip on this pair of lens-less glasses with the tiny bucket and ball on a string attached, and try, while looking like a demented chipmunk, to swing the little ball on its cord and drop it into the cup. With the classic styled black glasses, blue basket and orange ball, you will be filmed on a smart phone, it will be put on social media, and you will be famous for it for the rest of your life. Best to order a couple so you’re not alone.

Impressive, this 3-foot Lizard King. The 1:14 scale plastic model of a Tyrannosaurus Rex skeleton has 51 bones that snap together, then snap apart easily for later use, which is more than you can say about the original. Measures 36" long, and comes with a display stand. Bones are nicely aged for paleontological verisimilitude. Very nice kit, with legs, as they say! For ages 8 and up.

Please Note: Your entire order will ship standard ground when purchasing this item. Contact us for expedited shipping information. Thanks!

Yes, we have The Amazing Live Sea Monkey® aquarium kit, just like the ones from the comic books. The (9) piece ocean zoo includes brine shrimp eggs, growth food, water purifier, plus an official plastic feeding spoon, 32-page handbook, life insurance policy, growth guarantee, and the plastic aquarium with built-in magnifiers for viewing your little friends, and a vented cover. We'll pick the aquarium color that best matches your decor. Great gift for those budding young marine biologists. Ages 6+.

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. Tin and train car colors may vary. You add a "AA" battery and you're the engineer. 

Pop one of these roughly 1-1/4" dia stones into the toe of a sock, smash it with a hammer, and be the first person ever to see your real-as-Nature-makes-it geode!! Ninety percent of them have the familiar beautiful white crystals inside. Formed by volcanic action, they are found all over the world, but ours are from Mexico. There is no way to tell from the outside if they have crystal centers, but we will send you two just to raise your odds, and we haven't had a dud yet in our stores!! Much much more fun and satisfaction than buying one already cracked.

Take these (250) little translucent beads into the sunlight and they burst into assorted colors faster than you can say "assorted colors." How do they do it? Well, they're UV-reactive, that's how. Mostly pink, purple, rose, yellow and cream and they fade to a nice pearly color inside. Amaze your friends at picnics. Beads measure 5/16" dia x 1/4" with a 5/32" bore. Come with classroom application notes.

Squeeze this squishy version of the eight-legged tardigrade, aks moss piglet, aka water bear, and it takes up to (9) seconds to slowly morph back into shape while you feel your stress disappear like the cashews in a bowl of mixed nuts. Measures 4-1/2” long in green with the squeezability of a marshmallow. You probably don’t even know you need it, but you’ll know you needed it once you start squeezing it.

We not only know our pronoun cases, but we sell some of the fiercest little dragons this side of Drogo's funeral pyre. We'll pick one from our lovely assortment of molded snarling fire-breathers, all with either a wingspan of approx 6" or no wings but two heads. With highly detailed scales and teeth, these beasts come in green, orange, purple-ish, blue and gray, all in different poses of terror.

2" flywheel in a 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.
