I fail to see how you think you can put more red pixels in that red circle. It's completely red. It simply cannot be done. That circle is a representation of a 0 pH. There is nothing with more red in it than that. It's physically in-fucking-possible.

The reincarnated Lenny gets a lesson in Chemistry and never creates a -pH acid. This is partially due to the fact that it is impossible. Instead, he steps on a rather large thumb tack and falls down a short flight of stairs attempting to pull it out. His fall is broken by a small orphan girl, though, and Lenny is unharmed (aside from the rather large thumb tack that is still lodged in his foot). And so it was that which was the 6th book o' Lenny.

What is it they say about silence being golden?
