With this kit, kids can create an arcade out of electrical circuits - and then have fun playing with their creation! It's like two toys in one. Combining lights, sound, and motion, this is the most elaborate Snap Circuits kits yet!

The multi-model cabability of ENGINO TOY SYSTEM is proportional to the number of parts contained in the sets. The inventor pro series is the ultimate range more suitable for intermediaste and advanced users who literally "play to invent" ! The models created with these sets are bigger and more elaborate and can move with the new compact dual output motor. The series starts with the 40 models set and goes all the way to the 100 models set which has 2 motors and extra gears for even more complex builds. Each set contains printed instructions for selected 10 models while the rest can be downloaded free from engino's website.

Build this Strandbeest kit yourself! It has a very interesting mechanism: blowing into the fan makes the animal start walking against the wind. The wind power is conveyed to the legs by 2 gears. The 28-page science guide gives you the history of the real Strandbeest that Theo Jansen started building in1990. The guide also includes easy-to-follow assembly instructions.

Contains over 40 parts. 165 experiments can be completed using the kit, like a spinning lighted fan, a small RC car that moves forward and backward, and more. It stimulates the mind and teaches kids about electrical engineering, gears and rations in a fun and educational way.

Leonardo da Vinci improved upon the already-established catapult design when he introduced his own vision the the age-old military launching device. This design uses a double leaf spring to produce a great deal of energy in order to propel stone projectiles or flammable materials over large distances. A hand crank on the side of the catapult was used to load the spring. The scientific genius of Leonardo da Vinci is brought to life through these 10 articulated models. The inventions that inspired these snap-together replicas are taken from the pages of Da Vinci’s priceless and awe-inspiring notebooks. All models are made of plastic and require no special tools. Manuals are very educational and teach how these inventions have evolved into what they are today.
— Priscilla Moore, owner of Mr. Fub’s Party/Toys and More in Yellow Springs, Oh., told TDmonthly in a late Summer 2012 survey that this catapult is one of their best selling Science toys.
