Snap Circuits is an educational toy that teaches a kid about electricity through 305 different experiments with over 60 parts. The electronic discovery kit is perfect for future engineers who can create electronic circuits and electronic devices using different parts like slide switches, capacitors, microphones, snap wires, etc. All parts are numbered and have different colors for easier identification. They are assembled with a snap and there is no tools or soldering required. The toy runs on AA batteries and the package contains a plastic grid, electric parts and easy-to-follow manuals. The projects are arranged by complexity and it starts with a simple electric light and switch. After the projects are completed, it can be upgraded to the Snap Circuits Pro, Snap Circuits Extreme, or SCM-400.
