Complete knock down

Okay kiddo, so you know how sometimes grown-ups make things at home, like building a tower with blocks or baking cookies in the kitchen? Well, sometimes grown-ups also make things in big factories, but not just one at a time - they make a lot of the same thing all at once!

When they make things in a factory, sometimes they make them in a way that they can be taken apart later on. They do this so that they can send the different parts of the thing to other places, and then people in those places can put the parts back together again.

This is what we call a complete knock down! It's when something is made so that all the different parts can be taken apart and sent to other places, and then put back together again like a big puzzle.

So imagine building a toy car with blocks - first you make the wheels, then you make the body, then you make the seats, and so on. With complete knock down, instead of just keeping the toy car you made, you take it apart into all the different blocks again, and then you send those blocks to other people to put together the car for them. That way, they can have a toy car too, even if they don't live near your house!
