How many times have you burnt yourself on a hot pot? There’s just no way to tell visually if it’s hot or not, which really sucks. And hurts. The Thermochromatic Pot can prevent such things from happening. It changes colors depending on how hot it is.
When you see the Thermochromatic Pot turn red, that means hot so don’t touch it. When there’s no trace of red at all it’s safe to touch. This could have saved us all some burnt hands had it been released a few decades earlier.
