Best pool story? Tell 'em you use bleach and watch the fur fly! Listen to them tell you that it's TOO STRONG. After they finish freaking out, tell them that bleach is 6% Sodium Hypochlorite. Take them over to their liquid shock. Show them that it's 10% Sodium Hypochlorite. Ask them to explain why their stuff that is 4% stronger is safer. Watch them dissapear in a puff of logic.

Actually, I don't do this, because every now and then i need to go back to the store and buy something.
