Get ready for a little Greek, Kabuki, or your very own theatricality with our ready-to-paint, white plastic face mask. At 6-1/2" long x 5-1/2" wide, it's smallish and feminine (it has Julie Andrew's nose). You add your own artwork/makeup with an included brush and (6) paint pots: red, yellow, blue, green and (2) more GITD paints. Clever crafter-artistes will realize that with a little trimming, the molded clear plastic forms packed under and on top of the mask will make another pair of spookily paintable faces.

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.
