Geyser Gonna Love This
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
The geyser's little helper: you screw this 6" threaded and capped plastic tube onto a 2-liter plastic bottle of diet pop (not included) and fill it with Mentos® mints (included!). Pull the trigger pin and the mints drop while you watch it erupt in 25 feet of scientific deliciosity. The instructions say to select "an outdoor location," but we think that takes half the fun out of it.

Build Your Own Crystal Radio
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
A good basic kit with everything you need to build a very simple crystal radio. This is not hi-tech hi-fi. Geared for ages eight and up, it is a complete kit with wonderfully straight forward instructions which walk the experimenter through hooking up tuning needle, crystal diode, and earphone, and experimenting to find useful antennas. (Sorry wire coil is already wound.) Excellent education, recreation and discovery device all at the same time. A simple kit with hours of fun in it.

Crystal Farming Made Easy
Grow your own, because it’s so much easier than crawling around caves. Educational, too. The Ruby kit lets you grow (6) “ruby and emerald crystals;” the Amethyst kit grows (6) different “amethyst and diamond with fluorite“ crystals; and the Citrine kit lets you grow (6) different “topaz and citrine” crystals. The kits grow single and cluster crystals, the largest being approx 6” dia. Each kit also comes with a geode-esque mold to grow one of each of its crystal types inside, and includes vessels, chemicals, molds, casting plaster, and a 48pp instruction manual. And no, they’re not real diamonds, amethysts, rubies, but they’re awfully nice crystals. For ages 12 and up.
