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.

Lovely to look at, delightful to make jewelry out of. Our (25) piece set of polished gemstones includes: amethyst; howlite; tiger eye; hematite; amazonite; carnelian; sodalite; turqurenite; plain and rose quartz; rhodonite; unakite; snowflake obsidian; orange calcite; lemon jade; four varieties of jasper (serpentine; red, brecciated, picture and blue dalmation); and more. All approx 5/8" across.

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.

Maybe. Could also be a stegosaurus, triceratops or something else--that’s part of the fun of paleontological parenthood. Just submerge the 4-1/2” tall ersatz dinosaur egg into cool water and wait 48-72 hours while it cracks like a real egg and the baby dino grows to a be a foot long. If your mother won’t let you skip your bath for a few days (they’re like that, mothers, no scientific discipline), just use any container bigger than a 12” dinosaur.

Kiko.893. Just call her (or him--it’s unclear and we don’t like to ask) “Kiko” because “893” is her last name. Using just a screwdriver and side cutters, you build Kiko from this 107-piece S.T.E.M. kit. Set the mode for “Follow Me” or “Explore,” and Kiko will, yes, track you, or evade obstacles, respectively, via an infrared sensor and micro-controller programming. Interactive LEDs and sounds abound. Measures approx 5" x 5-1/2" x 6-1/2" when assembled with all (6) legs. You add (4) “AA”s for power, which is the least you can do for someone this cute. Ages 8+.

Actually, it's a set of (36) different little polished gemstones and minerals from around the world, all identical sizes (1/2" x 3/8" x 1/8" thick), mounted and identified by name and origin on an 8" x 10" card. Super nice at a super price, for teachers, designers or jewelry makers. The set includes amazonite, amethyst, aventurine, black obsidian, blue lace agate, buttermilk jasper, carnelian, Dalmatian dacite, dumortierite, fancy jasper, fluorite, gold stone, hematite, howlite, jadeite, lapis, leopard skin jasper, mahogany,obsidian, moss agate, nephrite, Picasso jasper, orange calcite, picture jasper, rainbow jasper, rose quartz, rhodonite, rock crystal, rhyolite, red jasper, snowflake obsidian, sodalite, serpentine, tiger eye stone, turquoise and unakite.

Lego® goes crazy with this 100+ piece kit with everything you need to build (16) different contraptions (be pretty stupid if they made 16 of the same contraption) for your amusement. In the mix are gears, pulleys, belts and axles, which you could turn into a rocket racer, Lego® launcher, donkey cart or scissor grabber, among other things. Includes a 50-page spiral-bound graphically illustrated instruction booklet. And, yes, adding Lego® pieces of your own just ramps up the fun.

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!!

It's Colorful. It's Magic. That's what the package says about this 3-1/2" tall specimen, and that's more than you can say about those big, clunky un-magical trees. Just slide two parts together, stand them up in the little tray with the magical water in it, and watch your tiny tree begin to bloom with an array of multicolor crystals after an hour. Reaches full magical bloom in 12 hours. Just the thing to watch on those days when the cable goes out.

About 30-40 highly polished stones, all shiny, translucent, or brightly colored, ranging from 3/4" long to 1/8" long. Great for mosaics, jewelry, or aquariums.

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. Excellent education, recreation and discovery device all at the same time. A simple kit with hours of fun in it.

Our best and prettiest-ever slices of polished agate, showing concentric rings of natural and dyed colors. The slices range from 3" to 4-1/2" across and from 1/8" to 3/16" thick. We've seen samples from milky white to blue, purple, red, yellow and brown. No two alike, by definition. We'll choose. Think scientific specimens, framed art, coasters, trivets, paperweights, or skipping stones for rich kids who don't want to search the beach for flat stones.

Among other things. (Sorry, no oranges.) Our each is a set of (4) laser-cut moving wooden gear models from U-Gears®, including a cat, a tractor, a human head and a heart. You like to fidget? Us, too. Each has (6) or (7) laser-cut parts and will fit in the palm of your hand when finished. They’re like worry beads in that you'll find yourself playing with them to help you inch toward inner peace. They’re press-fit, so no glue or tools needed.

Rock hammer with one squared chipping face and one pointy picking face, ideal for prospectors, rock hounds, construction and more. A single piece of forged and polished steel with a molded rubber grip makes this a solid and reliable tool that will last. 10-1/2" long x 6-1/2" across the 20 oz. head, 1-3/4 lbs. total. Well made. Good buy. Good bye!

Grow your own velociraptor? No, silly, this Dinosaur Plant is so-called because it’s 200 million years old. (OK, not this one, but ones just like it.) Looks like a ball of dead weeds, but add a little water and it will uncurl, turn green and start to grow again in a few hours, even after being dormant for months. You’ll get one plant, a bowl and some genuine lava-rock gravel.

Based on drawings from Da Vinci's Codex Atlanticus, this Pathfinders catapult kit uses a pair of bent wooden arms as springs to launch clay balls (included) over (4) meters at enemy fortifications (not included, go make your own enemies). The assembled model will be approx 9" tall on a 10" x 7-1/4" base. Made from pre-cut, untreated wood from sustainable forests, and built with pegs for added strength and verisimilitude. A 2013 Creative Child Magazine Top Toy of the Year Winner and a great resource for STEM activities. For ages 12 and up.

Sometimes when you want something done right, you just have to do it yourself. That seems to be the case if you want a 40-foot cactus or a plant that feels your pain. You choose: the Giant Saguaro or Sensitivity Plant kits. You’ll get a 4” x 5” plastic terrarium, a seed packet, some pink gravel, a germination disc. And yes, it’s going to take some time and some re-plantings before your Carnegiea Gigantea (named for steel and railroad baron Andy Carnegie) is 40 feet tall and weighs 4,000 pounds, but that will teach you patience. The sensitivity plant will be sensitive much sooner.

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.
