Subject: What makes disappearing ink disappear?

I'm writing a children's book on science-related practical jokes, and I need to 
know the science behind why/how disappearing ink works.

After using the search engine, there were just 2 hits for invisible ink, neither 
of which explains why disappearing ink disappears. One hit is a physics-related 
question that merely mentions disappearing ink. The other discusses 
color-changing markers and hints at why they change color. It doesn't directly 
discuss disappearing ink.

Thanks
