Thermochromatic ink
Have you ever played with a toy that changes colors when it gets hot or cold? This is kind of like that!
Thermochromatic ink is a special type of ink that changes color when it's exposed to changes in temperature.
For example, if you printed a picture with thermochromatic ink on it and held it in your warm hands, the ink would start to change colors right before your eyes! It's like magic!
Sometimes, people use thermochromatic ink for fun things like mood rings or t-shirts that change color when you wear them outdoors. But other times, it can be used for more serious things like temperature-sensitive labels on food or medical supplies.
So, basically, thermochromatic ink is like having a secret message that only reveals itself when things get hot or cold. Pretty cool, right?
