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.

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.

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.

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 an educational air and water show! The Blow & Blast Bonanza™ from Scientific Explorer® teaches kids ages 12+ about air pressure, air density and buoyancy. They can mix chemicals that will inflate a balloon, make a lung-powered marshmallow shooter and a hover train, and test Archimedes’ principle of buoyancy. Kit includes baking soda, citric acid, (12) PVC pipes, (6) pom poms, (4) paper clips, (3) brass nuts, (2) balloons, (2) pipettes, (2) soda bottles & caps, a clear canister, a measuring spoon and an instruction booklet with (5) activities.

Happy Atoms® is a triple crown champ in science education with a 2017 Auggie Award, a Parents' Choice Silver Award, and the 2017 KAPi Ed Tech Award. The atom and molecule game kit includes plastic atoms with magnetic electrons and bonding sites for use in (76) activities. You’ll discover the identities of (52) molecules by scanning with an app, and learn about the state of matter, bonds, molecular geometry and much more. For ages 10-17, and requires an iPhone or iPad running iOS 10 or later, or an Android device running 4.4 or later with 1GB RAM minimum with camera. Because of the camera phone tie-in, the kit becomes an on-going game.

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.

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. And yes, it will work with soy sauce apple juice, diet cola, whatever, if water strikes you (clock joke there, no charge) as boring. Also includes a 10-page manual. Ages 8+.
