It's Colorful. It's Magic. That's what the package says about this 3-1/2" tall specimen, and that's more than you can say about those big, clunky un-magical trees. Just slide two parts together, stand them up in the little tray with the magical water in it, and watch your tiny tree begin to bloom with an array of multicolor crystals after an hour. Reaches full magical bloom in 12 hours. Just the thing to watch on those days when the cable goes out.

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.

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.

Making stuff crystal clear is boring. Grow your own red, blue or purple crystals with these amazing Magical Crystal growing kits.

Chemiluminescence, which is glow-in-the-dark to anyone who doesn’t like six-syllable words, is a favorite here. Half the warehouse glows in the dark, and that’s not counting the staff.

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.
