Use this little stainless beauty to teach teenagers and older students how heat engines work Then keep it on your desk, where you deserve to have it! This low-temperature-differential Stirling engine is beautifully machined. It works with hot water, ice water, a combination of hot water with ice cubes, or a hair dryer. It measures 5-3/4" tall with a 3-5/8" dia flywheel and a 3-1/2" dia x 7/8" tall base. The speed with hot water is approx 150 rpm. This is a real showpiece, the best we've ever seen at this price. Includes a 7-page instruction booklet.
It doesn't get much cooler in the robotic-arm-kit game. The assembled arm is 15" tall x 9" long x approx 3-1/2" wide. It's 2-pronged hand opens to 1-3/4", lifts up to 3.5 oz, swings 120 degrees at the wrist, pivots 300 degrees at the elbow, and sits on a base that swings 180 degrees up and down and rotates 270 degrees, like, well, an arm. Controlled by (5) 2-axis joy-sticks and powered by (4) D-Cell batteries that you provide. Includes a hand-mounted light and over-torque and gear-breakage alarms, which is more than your arm has. Requires simple hand tools for assembly and is made for ages 13 and up.
Gyroscopes, not Greek sandwiches with tzatziki sauce. This multi-award-winning, 102-piece kit from Thames & Kosmos features (7) projects using motorized gyroscope-based science. Includes a gyrobot, personal transporter (think Segway), gyro horizon, gyrocompass, balance game, tightrope walker and flight simulator. Includes a 24-page manual and requires (3) “AAA” batteries and a little curiosity.
Chemiluminescence, which is glow-in-the-dark to anyone who doesn’t like six-syllable words, is a favorite here. Half the warehouse glows in the dark, and that’s not counting the staff. All of which is why we’re selling this 30-piece Glowing Chemistry kit from Thames & Kosmos. Comes with 3g of luminol, 6g of potassium hexacyanoferrate and 12g of sodium carbonate, plus test tubes, pipette, goggles, measuring cups, stir sticks and UV beads among other stuff, including a 48-page manual with (22) different experiments (because 22 of the same experiments would be stupid). For ages 10+. Made in Germany.
OK, glass with blue LEDs, but still. This is a Newton’s Cradle, always seen with steel ball bearings, but this time with frosted glass balls glowing a stunning bright blue while they swing on wires and prove Newton’s Third Law, and if you have to look that up you shouldn’t be reading this catalog in the first place. Just kidding--it says that for every action there is an equal and opposite reaction. You knew that. Newton would have ordered multiples of this beauty for all of his friends. Measures 7-3/4" tall on a 7" x 6" base with the standard (5) globes. You add (6) “AA” batteries for the glow.
Yet another great Snap Circuits® kit, this one based on lighting and optics, with a bonus 3-dimensional circuit board. Includes (50) parts and over (150) projects. Special components include an infinity mirror; red, green, blue and white LEDs; 6-way gel wheel; photoresistor; and a diffusion lens. Parts compatible with all other Snap Circuits® kits, too.
Build yourself a kid with a career in electronics. Start with this Snap Circuits® Motion kit with over (50) parts and instructions for (165) projects, including a mini-car, crawler, motion detector, tilt sensor and others. You add (4) "AA" batteries, conveniently available right here at your favorite supplier. From Elenco®.
Nothing beats Marble Mania® kits for table-top Rube Goldbergian fun. Depending on how much time you have on your hands, we suggest The Crankster, with over (100) pieces, including ramps, tubes, gears and a marble elevator (which will take an hour or two to build and will be approx an 18" cube of madness); or The Sidewinder 2.0, with over (200) pieces, including ramps, drops, gears, and an Archimedean screw marble lifter. Should take 3-4 hours to build and will stand about 2-1/2 feet tall, but can be set up in several ways.
You can’t start robotics too early. The Robot Engineer from Thames & Kosmos won ASTRA’s Best Toys for Kids 2016 in the Constructive Play category. Made to give kids 3+ a head start on STEM, it’s a 53-piece plastic construction set with a 32-page storybook for building (10) models with moving parts, including lots of wheels and gears sized to fit smaller hands.
