It's a joke.

Supposed to trick the main character into thinking that he's trying to clean up himself.

The writers just made it up. Funny scene, though.

There's no such thing as H2O9..I saw the movie too and i thought there such thing..I asked my former chemistry teacher about it and he said there's no such thin...its probably a spoof or something..

but this is possible to make right, if there will be a experiments or methods to do?
