The budding home scientist and horticulturist will both delight in the ease with which this self contained soil test kit brings discovery. The kit measures not only ph., but also Nitrogen, Phosphate and Potash content and contains material for 40 tests. Since these are the essential ingredients affecting plant nutrition, we see a science project in the making: experimental plant growth in soils with different amounts of acidity and/or nutrients. From Luster Leaf(tm), the kit is entirely self contained and includes complete instructions for use and explanations. Be careful, please, the kit does have chemicals and should not be used by young children without supervision.

AKA hand boiler. An exotic bit of hand blown glass with a bulb at top and bottom connected by some zippy tubing that spirals, loops, and/or jogs. In the closed system is some colored liquid (methyl chloride) that is very light. Hold the lower bulb in you hand and as the air in the system is warmed it pushes the fluid through the loops to the upper chamber. When all the liquid is pushed out of the lower bulb, expanding air will bubble through the tubing making it appear that the liquid is boiling. WARNING! The glass is fragile and the liquid is nasty. If you drop the thing on e.g. the kitchen tile, it will eat the finish off the tile and the stain in the liquid will permanently stain the floor. So don't let kids handle this item unsupervised. About 7" tall, it is a favorite in our stores.

A collection of 11" x 14" top quality medical charts. They cover topics such as organs: "Eye" or "Skin", systems: "Digestive" or "Female Reproductive" and disease or conditions such as: "Cancer" and "Obesity". They are on heavy coated paper suitable for putting up in, say, a classroom where they would be excellent teaching aids. Most are overruns that are imprinted with the name of a drug at the bottom and were distributed as part of a promotion. A few have misspelling misprints. Because of varying quantities and a horrendous sorting problem, we cannot give you the luxury of picking your favorites from a long list. We also have (2) large (20" x 26") wall charts, One on hypertension and one on the male reproductive system.

From France comes this fun mechanical plastic bird that really flies by flapping its wings. It is about 8" long and has a wingspan of 16" tip to tip. Snap the wings in place, wind up the rubberband drive and toss it gently into the air on its maiden flight. It flies up to fifty yards with a satisfying fluttering sound. Comes with a spare rubberband drive mechanism.

Pop one of these roughly 1-1/4" dia stones into the toe of a sock, smash it with a hammer, and be the first person ever to see your real-as-Nature-makes-it geode!! Ninety percent of them have the familiar beautiful white crystals inside. Formed by volcanic action, they are found all over the world, but ours are from Mexico. There is no way to tell from the outside if they have crystal centers, but we will send you two just to raise your odds, and we haven't had a dud yet in our stores!! Much much more fun and satisfaction than buying one already cracked.

It's 1953 all over again! Now you can buy your favorite childhood toy for your grandkids! We have the original Burp Gun that rapid-fires small ping-pong-type balls the length of our office as fast as we can pump the barrel (no batteries needed). All right, we remember the grip of the original as plain old brown plastic, and this one is bright red - but kids are used to a lot more stimulation these days! The Burp Gun, which comes with 15 balls, is 30" long when fully extended. The Burp Pistol, which comes with 7 balls, is 12" at its smallest and extends to 17". Great fun - but maybe you'd better buy a couple of bags of extra balls (10 per bag). Big sisters still stomp on them.

We love these! You're going to love these! Your kids are going to love these! Hundreds of clear marble-sized bubbles can cover the floor, cling to the sides of furniture, land on your arm. They float enchantingly, rising on air currents you can't even feel. After a few seconds, the bubbles are hard enough to catch or stack. Some will still be perched in out-of-the-way spots a day later. Touchabubbles goop, thicker than the bubble-blowing liquid you're familiar with, comes in a 4" plastic test tube with a wand built into the cap, and a clip on the side so you can carry it in a shirt pocket. The goop is nontoxic, but it tastes really bad, and you probably won't want these landing on expensive tabletops, so kids under 8 should have adult help with them. They should be sharing the fun anyway!
