Disappearing Ink

TimesOnline: Scientists have unveiled a new kind of 'ink' that disappears from a page 24 hours after printing, allowing paper to be re-used.
Mission Impossible-style self-destructing messages may soon cross from the realm of fiction into the wilds of the nine-to-five office, according to scientists who have developed printer ink that vanishes after 24 hours.
When a document is printed on the reusable paper, the text initially appears similar to normal printed text – only in a shade of dark purple, rather than black.
Eight hours later, however, the image is a shadow of its former self and after a day – much like the McFly family photograph in Back to the Future – it is gone completely.
The blank page can then be put back in the printer.Read On

Take a lemon. Cut in half. Dip a pointy thing(fountain pen?) in it. Pick a blank piece of paper. Write "I'm so 1337". Bring the paper near fire, don't burn it. Viola! I'm so 1337 :)

Used to do this in class 2 or 3. Good for secret messages.
