Binary chemical weapon

Okay kiddo, so you know how sometimes you mix things together and get a new thing, like when you mix blue and yellow paint to make green? Well, some people can mix two very dangerous chemicals together to make a really bad thing called a binary chemical weapon.

These chemicals are so bad because when they are mixed together, they can explode and hurt or even kill a lot of people. That's why they are not allowed to be used in war or against people.

But, some good scientists have come up with a way to make it harder for bad people to use these weapons. They made it so that the two chemicals can only mix together when a special thing is added, like a key or a code. That way, if bad people get one of the chemicals, they can't do much harm because they don't have the other one or the special thing to mix them together.

So, in short, a binary chemical weapon is a really bad thing made by mixing two chemicals together, but smart scientists have made it harder to use them by adding an extra step to keep people safe.
