i dont know... windex can get wild sometimes O=
That reminds me -- when I was in college, Kool-Aid came out with some bright blue drink mix. It looked just like Windex when we made it, so I took a near-empty Windex bottle, washed it out very well, and filled it with the bright blue Kool-Aid. Then when an unsuspecting victim came to visit our dorm room, I'd pull out the bottle, unscrew the spray top, and chug away! Freaked a few people out with that prank. 
I would also take it to class and just spray it directly into my mouth.
