Y’know, just forget about Xerox Corp and their fancy elitist Innovation Group! They spend untold millions on their grumble-grumble disappearing ink! And they spend billions more on their razzem-frazzem invisible ink! Y’know, a humble print artist like me can’t afford to fund a team of research scientists operating from a shadowy mountaintop base.

You want print innovations on the cheap? MAKE Magazine to the rescue! Make your own “invisible ink printer” by filling your yellow ink cartridge with concentrated lemon juice. All you need to do is ruin your printer!

P.S. Xerox, I didn’t mean it… I still love you, really…Please, come back!
