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!!
You supply the pot, we'll supply a dozen Venus Fly Trap seeds and a little sack of soil in a 4-3/8" x 2" dia plastic growing tube, plus an instruction sheet on the care and feeding of everyone's favorite meat-eating foliage. Gestation is about (14) weeks, so order early if you're planning a birthday surprise for someone.
We’d start with triops, lovely little crustacean-ettes that have been around since Triassic days. You pick the Ghost Triops, see-through honeys, or the larger Gigantic Triops (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+.
Yes, we have a Sea Monkey® aquarium kit. The (9) piece aquarium kit
includes eggs, food, water purifier, plus an official plastic 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.
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.

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
Can you dig it? Yes, you can.

For ages 6+, but really you’re never too old for dinosaur dung.
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.
