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.

So you don't have a gas jet in the garage? You don't think Margie and Ted are old enough to handle the high temperatures of a Bunsen burner? Our alcohol lamps are the answer. They burn alcohol (available at the hardware store), and are hot enough to boil water, to soften glass tubing for bending, and to generate the chemical reactions generally called for in science projects. Lamp A is shaped like a long-necked ink well, 3-1/2" tall x 3" dia at its widest point and comes with a wick assembly and a handy little glass lid/extinguisher. Lamp B is 2-1/2" x 2-1/2" x 2-1/2" glass bowl with a wick assembly that brings the whole to a height of 4-1/2".
