Xerox Self-Erasing Paper

Some documents are so secret you’ve got to keep them safe from even yourself, and that’s why Xerox invented self-erasing paper. The info fades away after 24 hours, so only your photographic memory can keep the info locked in. This is all due to a molecule that creates the print under ultraviolet light and then readjusts after 24 hours or under heat to make it disappear.
This may put the recycling industry out of business.
This paper has yet to disappear from Xerox’s Palo Alto Research Center.
