What kind of ink that is invisible then appears when water is added? December 7, 2009

I wanted to find a special invisible ink that appears when water is added. Affordable would be the best but you can also tell me the expensive ones if there are.
Could there be an invisible ink but when water is added, color will appear.

Invisible ink or lemon juice. Also other types of fruit juices. Pee too.
