Geology for those with short attention spans? The original Magic Rocks®, of course! Mix the solution in a jar of water, drop in the pebbles, and watch them grow into a forest of multi-color stalagmites. Growth starts in 10 minutes, is impressive in 30 minutes, and complete (up to 4" tall) in 2 hours. Extra credit if you can make it grow stalactites by gluing the pebbles to the bottom of a jar, then pouring the solution in and turning it upside down. Who knows? Maybe it will work. Comes with a set of marine decals to decorate the jar. Definitely not for use with living fish. For ages 10 and up.

From Zimpli kids we bring you SnoBall Battle Pack. A packet of Sodium Polyacrylate that turns Science into an all-out snowball fight. Just add water to create your own snow. Packet contains 2.82oz to create up to 60 snowballs. The rest is up to you and your kid's friends. Winter not included.

Our micro rocket packs a lot of fun into a small package, much like hockey's original Pocket Rocket, Henri Richard, the 5' 7" brother of Maurice "The Rocket" Richard. Unlike Henri, this rocket's powered by baking soda and vinegar (not included), and actually flies quite high. Bullet-shaped, it's just 2-3/8" tall x 13/16" dia and sits on a launch base 2-3/4" tall x 3/4" ID. For rocket scientists over 5 years of age.

Making stuff crystal clear is boring. Grow your own red, blue or purple crystals with these amazing Magical Crystal growing kits. You get approx 4 oz of mono-ammonium crystal, a 2-3/8" dia concave base, some appropriate food coloring flakes, a 3-3/4" x 2-3/4" dia clear plastic container, mixing stick and instructions. Recommended for ages 10+.

rom Crazy Creations, this Brain Dome Kit is basically a lab for creating and assembling your own spooky creations out of hardening gel, or as the box says, turning “slime to stone.” Includes molds for spider parts and human bones, as well as a large brain-shaped device to cure the gel. Think of the brain sort of like a potter’s kiln. You make each limb individually, cure them, and then add joiner gel to create posable joints. There’s string to hang pieces from, too. Add the Crazy Creations Refill Set, a slime gel kit to go along with the Brain Lab Kit. The Refill Set comes with gel, which “sets from slime to stone” in less than 6 minutes. Contains a random (1) of (3) possible molds (skeleton, dinosaur or spider), (2) bottles of hardening slime (red and blue), and a bag of decorations, including flies, maggots and ants.

Including bubbles as big as your grandmother. You get 2 oz of fluid; (4) straws; a mouthpiece; cubical, pyramid, star and round frames, 108" of yarn (for the bubbe-sized bubble); a tray and instructions for (11) kinds of bubble activities. For ages 5 and up.

It’s why you come here, isn’t it? Our each is (10) plastic canisters, each with a teaspoon of green cave-snot slime powder inside. When mixed with two teaspoons of water you’ll get approx a 1/2-ounce of nauseating gooey green gloop like the stuff that drips from cave ceilings and turns into stalactites someday. Scientific fact: the contents are actually guar gum and potato starch, because genuine cave snot is really hard to collect, and probably against cave rules. Great for a kid’s birthday party--obviously.

Don't take it the wrong way—slimeball is the official designation for scientific types who specialize in slithery goop. You could ask anyone.

On the heels of the Pineapple Watch, comes this H20 Clock Kit that features a digital clock powered by liquids. Includes a 3/4" LCD clock display, (2) 4" vials that hold 3 oz each, lids with prewired copper and zinc electrodes, and a base with spring terminals to wire and hold everything.
