of fun right out of the box; there's no complicated setup or need for a computer. Robosapien's 60-plus commands are easily controlled by an ergonomic remote, not some impossible-to-understand logarithms or formulas. Robosapien is a sophisticated fusion of technology and personality. Loaded with attitude and intelligence, Robosapien is the first robot based on the science of applied biomorphic robotics. With a full range of dynamic motion, interactive sensors and a unique personality, Robosapien is more than a mechanical companion -- he's a multi-functional, thinking, feeling robot with attitude! Sit back and watch as this 14" personal robot goes through movements and activities you never thought possible in a home robot, from its hilar...  (less)

butter and garlic, youd be disappointed with a mouth full of high density plastic. Walking King Crab is powered by a mini solar cell (included) and demonstrates alternative energy principles. No batteries required and less than thirty-five parts to assemble. Recommended for ages 9 and up.  (less)

moment, but still requires a way to heed out of harms way. The suns rays power this mini solar kit to slither along to safety. The mechanical movements simulate the movements of its soft-bodied derivative. Because its home is above ground, Attacking Inch Worm has a hard plastic body to protect itself. This slender creeping animal kit demonstrates alternative energy principles. No batteries required and less than fifty parts to assemble. Recommended for ages 9 and up.  (less)

grasp the basic principles of electronics. The Student Guide for the SC-750R includes 138 pages of educational curriculum. Written with the help of educators, the Student Guide is essential in covering all topics related to electricity and electronics being taught in middle schools and above. Includes real world applications and problem solving quizzes. The optional Teachers PAK Model TG-750, sold separately, includes five project books, teacher guide, and three student guides. The teacher guide is meant to prepare educators for proper introduction of Snap Circuits and guide them through each chapter with quizzes for students to test their knowledge. Topics Covered: Resistors; Capacitors; Transistors; Motors; Integrated C...  (less)

soldering are required for assembly. When assembled, SPIDER III emits a light sensor beam; detects obstacles in its path, signaling it to change direction and continue on a new path. A bat flies in the dark sensing its own super-sonic wave reflecting back from obstacles. Likewise, SPIDER III emits light sensor rays and judges by the reflection if there are any obstacles in front and gives signals in the form of electric pulses to alter the rotating direction of the left side motor to evade obstacles. Requires two "AA" batteries (not included). This kit requires a more challenging soldering of the circuit boards and mechanical assembly. Recommended for ages 12 and up.  (less)

and display. The kit includes 8 oz. of gemstone rocks ready for their three-step makeover with coarse grinding powder (Step 1), fine grinding powder (Step 2), and polishing powder (Step 3). Once kids have finished the polishing process, they can make jewelry and key chains with the kit's included supplies: an 18 inch silver-tone chain for a necklace, four adjustable rings, three key chains, twelve setting holders (two styles), twelve jump rings, and glue. From start to finish, this is a very satisfying activity for children from age ten.  (less)
