Geology for those with short attention spans? The original Magic Rocks®, of course! Mix the solution in a jar of water, drop in the pebbles, and watch them grow into a forest of multi-color stalagmites. Growth starts in 10 minutes, is impressive in 30 minutes, and complete (up to 4" tall) in 2 hours. Extra credit if you can make it grow stalactites by gluing the pebbles to the bottom of a jar, then pouring the solution in and turning it upside down. Who knows? Maybe it will work. Comes with a set of marine decals to decorate the jar. Definitely not for use with living fish. For ages 10 and up.

Everything you need to build a little DC motor is included in this kit (except sandpaper, screwdriver, scissors and, of course, an AA battery). The instructions are simple and explain the theory as well as assembly. Fun and educational for ages 12 and up.

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.

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).

This is your classic dual-threaded connector tube to link a pair of plastic bottles together, demonstrate tornado action and learn once and for all about the fluid dynamics concept of a vortex. In an homage to Dorothy in Kansas, this connector tube also comes with a tiny cow and a barn included. Also a lot of glitter, which we suppose is Oz-like. Includes instructions and a surplus-inducing QR code (to see a video) that's as dead as the Wicked Witch of the West.

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.

Just the one, actually, but it’s been sliced in half so the pair is perfectly symmetrical and mighty pretty. Although ammonites have been extinct for 65,000,000 years, we’ve got their approx 1” dia fossils for you. Our each is a book-matched pair of polished ammonites fossils of a single critter halved and polished to a bright symmetrical shininess. The colors vary from light tan to dark brown and we’ll pick because we have impeccable ammonitical color-shade taste. And yes, they’re just screaming to become cuff-links or earrings.

Heat-sensitive duct tape changes color and gets lighter the more heat is applied, as from sunlight or your paws. Why, you ask? Billy, our social media guru, says if you ask why, you don't deserve it. Just accept that it's cooler than all of the other duct tape, especially if you make a prom dress or tux out of it. And yes, if you had a broken chameleon you could try fixing it with this, but don't tell anyone we said so. Tape is 1-7/8" wide and 30 feet long.

When you peer through your magnifying glass at this specimen, or focus your microscope on it, even at the lower magnifications which work best, you're looking at one big bug. Make that (4) big bugs.

Set 2 is a cricket, locust, yellow leaf beetle, and crab. No, not a crab louse or a crab spider, but definitely a crab ugly.

Electronics fans, musicians and budding Sci-Fi sound engineers will love this little starter electronics kit for making a mini version of a theremin, the venerable capacitance-based instrument that’s synonymous with eerie sounds. This one skips the volume antenna, but has a quantization mode as well as a continuous swoop via the pitch antenna. You add a 9V battery and some minimal soldering skills. Includes all parts, including IC sockets. Measures 2” square, and includes excellent instructions. You might want to get a little project box for it. Made in the USA for Madlab/Velleman.Ages 10+.

Shoot one of these little plastic arrow-helicopter-rotor gismos straight up with the included rubber band launcher and watch it soar as far as 300 feet!

Could be a new line of cologne, but in fact, it’s a clever kinetic action demo kit called Wave Wires® with magnets marked for polarity, and mounted on (4) 8-1/2” long wires attached to a 4-1/4” square steel base. Includes a dozen 1/2” dia steel disc weights, an acrylic ring and an 8-page activity booklet.
