Where this inconspicuous black foil warms up over 28°, it begins to turn red, then increases over orange, yellow, green and blue to violet, to turn black again above 34°. When it cools down, the process goes backwards again. This property, called thermochromism, enables impressive experiments bordering on magic: placed on the hand, it appears after a short time as a coloured ghost image. If it is preheated and placed on a coin, for example, the rapid colour change shows the heat-absorbing properties of the metals.
Let your experimental imagination run wild – you won’t want to stop!
