This BMW has a truly unique paint job thanks German graffiti artist Rene Turrek. The cars paint appears normal until boiling hot water is poured on top of it, revealing an impressive HULK mural underneath. Checkout the video to see how it works.
It's a pretty neat and an original idea, but unless it's raining boiling hot water then we can't really see it having much use in the real world. Let's hope they make something similar which works with cold water instead.
