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.

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.
