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.

Home robotics, bubeleh. Build a working hydraulic arm with this excellent 66-piece kit from Pathfinders' Simple Machine series. Structure is die-cut plywood and the kit includes tubing, (3) syringes and glue. You'll need a ruler and scissors. The finished arm will be approx 13-1/2" tall and will reach out over 16" and rotate 90° on an 8-5/8' x 6-7/8" base. Comes with a 12-page manual and uses water. Beautiful, too. For ages 8+.

Create your own crystal garden and you'll never again have to run out to the store in the middle of the night for more crystals.

Add food coloring if you want to change your tasteful monochromatic crystals into a phantasmagoric garden of color. You provide the bowl, vinegar, food coloring and warm place. For ages 8+ with adult supervision.

Don't panic. A meteorite is speeding toward you, but it will only hit your mailbox. These small hunks of genuine meteorites are approx 4,200 years old and have been harvested from Chaco, Argentina. (We never miss the meteorite harvest in Chaco.) Most will weigh 20-33 grams and measure approx 1-1/4" x 3/4" x 1/2", which is very dense. Carry one in your pocket and you'll never be hit by a large meteorite. (And if you are, we'll give you double your money back.)

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.

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.

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.
