Temperature sensitive card
Termochromism - a property that makes impressive experiments bordering on magic possible.
Where this inconspicuous black foil heats up above 28°C, it begins to turn red, then increases through orange, yellow, green and blue to violet, before turning black again above 34°C. When it cools down, the process goes back to black. When it cools down, the process goes backwards again. Let your experimental imagination run wild - you won't want to stop!
