Demonstrate Current Flow Through Water AnalogySafe and easy to operate, transparent tubes and a low voltage operated motor are mounted on a rugged metallic frame. The pump forces water to flow through the circuit made of plastic tubing which is connected to glass tubes of different diameter, representing the flow of current. The top of the device represents a manometer. Ideal for classroom demonstration, the metallic frame is provided with legs, so no other additional support is required. Requires low voltage power source. Size: 61cm W x 59cm H x 2cm D.
