Exergia SeeSaw Kit Bimetal Candle SeeSaw

Exergia SeeSaw Kit Bimetal Candle SeeSaw

Ref: Exergia-106023

The bimetal spiral spring is the key component of this engine. A bimetal consists of two metals with different rates of expansion when heated. When the spiral spring is heated over the candle, it twists moving the bead to the other side making the see-saw tip over. This moves the spiral spring away from the flame, the bimetal spring cools down until it has contracted enough to make the see-saw tip back into its original position and start the cycle again."
