Simple, yet clever 1" dia. by 3" long plastic device to demonstrate the vortex effect of a tornado. Partially fill with water one of the two half-gallon size plastic soda bottles which you supply. Screw the bottles into opposite ends of the tube which we supply. Tip so the full bottle is on top and give it a circular starting whirl. Presto! You have a vortex. Call it a tornado if you're a meteorologist, a Charybdis if you're a classicist, or a whirlpool if you're into oceanography. Lots of fun and a fine opportunity to attempt to explain the effects of the earth's rotation on water draining out of a bathtub. The phenomena are related we're told, but good luck!!

Yes, we have The Amazing Live Sea Monkey® aquarium kit, just like the ones from the comic books. The (9) piece ocean zoo includes brine shrimp eggs, growth food, water purifier, plus an official plastic feeding spoon, 32-page handbook, life insurance policy, growth guarantee, and the plastic aquarium with built-in magnifiers for viewing your little friends, and a vented cover. Great gift for those budding young marine biologists. Ages 6+.

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.

We’d start with triops, lovely little crustacean-ettes with compound eyes that have been around since Triassic days. You pick the Ghost Triops, see-through honeys, or the larger Gigantic Triops, the biggest of the triops which is gigantic among lesser beasts. In both cases you get eggs, baby and adult food, and a pipette. You add a bright light source, bottled natural spring water and a small tank. They hatch in a day or three, are full grown in a month or so, and have a life-cycle of up to 90 days.  Ages 8+.

Triops: way cooler, bigger and more active than sea monkeys. They're dinosaur shrimp, leftovers from some 200 million years ago. Don't eat them; just grow them and enjoy this bizarre & ancient display of nature! In the kit you get a kidney-shaped tank 2-3/8" tall x 8-1/2"x 5-3/4", a very informative instruction booklet, and a packet full of triops eggs and food. In the starter pack/refill pack you get tripos eggs, food, conditioner and directions. Add the eggs to water and watch them go; they'll hatch in a day and reach 1" to 2" or more in a few weeks. Really easy to do, and really cool too.

Budding meteorologists will love this Weather Science kit from Green Science. Includes experiments with lightning, static electricity, cloud-making, greenhouse effect, water cycles and acid rain. Comes with thermometers and holders, a balloon, seed tray, pH paper, and sundry plastic instruments. You add a few common household items.

before we dip our tongues into it. You might want to, too. Try Watersafe® Well-Water Test Kit, a robust 10 parameter, single-use kit made for testing city water or well-water. Contains tests that will detect lead, coliform bacteria, pesticides, nitrates, iron, nitrites, pH, chlorine, copper and hardness. Includes an instruction manual and EPA drinking water standards. Easy to use, with your water quality results on the spot.

You can’t put science on a stick, but you can put it in a can. The Crazy Scientist™ Water Gel Science Kit for young researchers comes from The Purple Cow® in a 6-1/2” x 9-1/2” x 1-1/2” tin. For ages 8+, comes with (14) experiments, containing sodium polyacrylate, color tablets, polymer gel beads, spoons, pipet, test tube, tubing and a 15-page manual.

Nothing beats owl pellets for the edification of budding biologists. These are from barn owls and they're domestic, yurped up by your American barn owls, each with a skeleton inside. Keep them refrigerated to keep the moths away. Most are approx 1-1/2" to 2" long.

Who says demonstrating kinetic and potential energy isn’t more fun than a barrel of monkeys? Well, the monkeys. But everybody else will enjoy this rubber-ball-based energy demo toy. Includes colorful rubber balls at 1-7/8", 1-1/4" and 15/16" dia on a 5” plastic rod, capable of shooting one of three 3/4” balls (you’ll get two spares) up to 5X higher than the drop distance. Comes with a pair of safety glasses, just to be safe.
