Product Description: Ready to learn about how airplanes work by building awesome flying gliders? With this kit, you can build five different glider models and test them to learn how they fly. You can try all sorts of wing positions and angles. You can even design your own gliders! You’ll learn how wings generate lift and how the wing’s shape and the configuration of the wings affect the plane’s flying performance. (16-page manual, 44 building pieces). Ages 8 and up.
— In a May 2014 survey Mary Porter Green, owner of Curiosity Zone in Broadlands, Va., told TDmonthly that Thames & Kosmos makes her store's best-selling activity kits. They sell dozens of toys from the brand each month.

Build an energetic bouncing robot that uses an electric motor and a springloaded mechanism to jump forward in a continuous motion. Watch the robot crouch down, compress its coil spring, and store up energy. Then see how it instantly extends its legs and releases the stored energy all at once, launching itself upward and forward. Experiment with the metal coil spring to discover how the robot’s jumping mechanism works. See if the robot can jump over objects in an obstacle course you design for it. Learn about elasticity, potential and kinetic energy, the spring constant, cams, and linkages. Build seven other functional models using the same mechanical components — the spring, cams, and motor — to perform other tasks and demonstrate physical science principles firsthand. Construct a car that moves forward on spiral-shaped wheels. Build a crab that moves sideways, a kicking machine that uses the spring-loaded mechanism to propel an object away, a pitching machine, and a grappler claw. Assemble a fun amusement park ride that spins around using the electric motor. Learn about the physics of force, mass, and weight by making and experimenting with a spring scale. The full-color, 24-page instruction manual provides step-by-step illustrated assembly instructions.

A souped-up version of the best-selling Remote-Control Machines kit! Build your own motorized vehicles and machines and control them with a wireless remote control unit. A unique six-button infrared remote allows you to control three different motors simultaneously, moving each of them forward or in reverse, with easy-to-activate touch sensors. The three motors can be combined to make complex vehicles and machines in numerous configurations limited only by your imagination. Assemble 20 models demonstrating different ways in which the motors can be used including a three-wheeled car, bat-bot, stag beetle, robot, battle car, ball collector car, forklift, tunneling vehicle, truck, drilling machine, crane, robotic arm and more. After you have built the models in the instructions, you can design your own remote control creations! The kit comes with three motors, remote control unit, battery holder, and 155 building pieces. 128-page, full-color instruction book.
— In a September 2014 survey, Kai Rady, owner of Shenanigans Inc in Charlottesville, Va., told TDmonthly that Remote Control Machines is the store's best-selling science & nature toy.

The Geek & Co. Craft line connects science, art, and nature through fun, hands-on activity kits.

Fractiles - a Real STEM toy!

This set includes 48 brilliantly colored flexible MAGNETIC tiles and a color-Illustrated cardboard CD-style package to store the tiles. Board not included. Fridge Fractiles make great stocking stuffers and can be used on a fridge or filing cabinet. They are made in the USA.

"For the past several years, my wife and I have featured Fractiles in workshops we do with public school students. We have been following the currently popular STEM philosophy of combining Science, Technology, Engineering, and Mathematics to get kids interested in how to teach themselves and learn independently, with really promising results. Fractiles is ideally suited to this kind of program and extremely popular with our students as it encourages creativity and innovation. We wish there were other materials of a similarly versatile and compelling nature." - Professor John L. Hall; University of Colorado, Boulder; Nobel Prize for Physics, 2005

"It is a perfect 'STEM' toy that teaches math while kids play.  In fact, it plays into 'STEAM' because it has a strong art component, too! Fractiles was way ahead of its time, and now is perfectly positioned to become a hot seller for all the families who are looking to enhance education through play!" - Sallie Kashiwa, owner/president of Timbuck Toys in Colorado

"We have carried Fractiles for several years and, on top of being a great selling toy, they have become one of our personal favorites. They are educational, reasonably priced, and made in America by a reputable company. It's very rare for a toy line to meet all of those qualifications. " - Kristine Reed from Whispering Winds in Mr. Dora, Fla.
