Teacher: A catalyst is something that speeds up a chemical reaction, but it's not involved in the reaction itself.

Student: Um.. can you give us a real life example?

Teacher: Sure, I tell my son to clean up his room, he says no, I ask him nicely, he still says no, so then, I take out my belt and and ask him again, he runs up to clean it.

Student: O.o

Teacher: See, the belt it not never touched him, but it speeds up the reaction.
