Product Specifications
Science kit to make your own PotatOS IMPORTANT NOTE
PotatOS is a simulated science kit. It is not actually powered by the potato you supply. A single potato could not provide the voltage needed for LEDs and voice. An internal button-type battery provides power. However, PotatOS detects when it is connected to a potato giving the illusion of being powered by the potato. Gotcha? Good.
