What is activator?

That's a great question, but the word "activator" is a bit of a chameleon. Its meaning really depends on the context.

Lately, you hear it most often in crafting, especially for making slime. In that case, the activator is usually a borax solution or contact lens fluid. It’s the key ingredient that makes the glue mixture actually turn into slime.

In a scientific sense, an activator is a substance that increases the activity of something like an enzyme. It essentially ‘turns on’ or speeds up a chemical process. You might also see it in software, referring to a tool or key used to verify a license.

So, where did you come across the word? Knowing the context would help give you the perfect answer.
