Intruder! Intruder!
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
Someone has entered your room! You're not in there to catch them, but the infrared light barrier you built has sounded the alarm!

Magic Rocks
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.
