Kit candle boat thermoelectric

A kit to build a candle boat. The warmth of a tea light is enough to let the candle boat sail on the water. A tea light heats a thermo element on one side, water cools on the other side. The temperature difference generates electrical voltage, which drives the engine and thus the ship's propeller. Tools required: screwdriver and pliers. Suitable for people aged 14 and over. Operation with candle only under adult supervision.
