These are safe, clean (no wax) and easy to use. The durable liquid crystal strips embedded in the bars show how a red zone of 40°C moves up the bars. The colours give a dramatic view of conduction and the marked difference in temperature gradients in the bars is also visible. By immersing the heated bars into cold water shows how conductivity applies to heat leaving the metal. The tops of the bars are designed to be touched with a finger tip to reinforce the colour observations.
