GREAT SCIENCE PROJECT FOR THE LITTLE ONES:

CRYSTAL ROCK GARDEN

Growing this garden couldn't be easier: it never needs watering or weeding, and you end up with a bumper crop of cool crystals. As a bonus, you get a new understanding of how real rock crystals, such as those in geodes, form.

DIRECTIONS: Bring 1/2 cup of water to a boil, then add 2 ounces of alum (found in the canning or spice sections of supermarkets), stirring until the alum is dissolved. Pour the solution into a clear glass bowl half filled with assorted clean rocks and pebbles. Within hours you should be able to see alum crystals forming as glasslike squares. Within several days you should have a number of crystals to look at.

NOTE: Geodes and many other rock crystals were formed the same way, when water saturated with minerals seeped into spaces in rocks. When the liquid evaporated, the crystals were left behind.
