The pipe circuit
Water Pipe Circuit is a building toy that helps children understand the basic principles of electric circuits. The design compares the flow of electricity to the flow of water, so connecting a circuit becomes as simple as joining pipes. Each electronic component is sealed inside an independent module, and modules with different functions are given different colors. The module type and the light path that shows the current are engraved on the shell by laser. Each time a module is joined, the module lights up to confirm a correct connection. The toy is made of ABS and PC.
