ELI5: What is Entropy?
gpt
Entropy is the way that everything (EVERYTHING!) keeps getting more and more random. It's unstoppable.  
  
Take a piece of copper wire. Maybe 5" of nice, straight, copper wire. Now bend it in half. You have increased the randomness of the universe. Try and straighten it back out. You can't quite get it back to the same level of orderly straightness that it was before. You might even have made it worse (because before it had just the one bend, and now it probably has at least three from you fumbling to try and approximate straightness). 

Entropy is always increasing.

It's one of the reasons why we die. 

Now, go to bed.
