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.

THE 8 FOOT BALLOON

If the question is whether to tie a bunch of these giant latex professional weather balloons to a lawn chair, the answer is no. (The balloon bursts at about 82,000 feet anyway.) This is a true high altitude weather balloon, with plenty of fun, nonfatal uses. The cream-colored latex balloon is approx 40" dia when flaccid, you should pardon the expression, but has an 8-foot dia when inflated. The neck is 9" long x 1" dia. Scientists and meteorologists launch balloons to measure atmospheric conditions like wind speed and air pressure for weather forecasting, but clever inventors, teachers and the imaginative filmmaker are warned to launch the balloon carefully. The synthetic rubber material is delicate and not made to survive brushes with pavement, pine branches, or clumsy physics students. Red not available and only available in egg shell/cream color only.
