Mercury cadmium telluride

Okay kiddo, so you know that some things are hot and some things are cold, right? Well, scientists made a special material called mercury cadmium telluride that can help us see things that are too hot or too cold for us to see with our regular eyes!

This special material is made up of three different elements: mercury, cadmium, and tellurium. When these elements are combined in a very special way, they create a material that can detect tiny changes in temperature!

Now, you might be wondering why anyone would need to see things that are too hot or too cold for us to see with our regular eyes. Well, scientists use this material to make special cameras that can detect things like heat signatures from people or animals, or even from machines!

So next time you hear the word "mercury cadmium telluride," you'll know that it's a special material that can help us see things that our regular eyes can't see, like heat or cold!
