17 Heat-Sensitive Designs

I’m sure we can all recall that mothering tone (or stern father’s rumble) as we each reached over to touch that pretty, flickering flame. You know, the one that scalds and warns at the same time.

I must admit, though, the pretty colors that are displayed when heat is applied is just as appealing as the fire itself.
