coke or pepsi in a water gun it will do wonders for the paint on the car and to the pasanger as well. lol
keep it simple. throw a mcdonalds milkshake, no lid, willy nilly into the persons car. they will be upset.
Yeah but it's easier to keep coke and pepsi around and people tend to have those sitting around more. So how about a compromise. A large coke left over from McDonalds that's been sitting in the car. That would be GREAT!
