Xerox has invented a new form of Self Erasable Paper that would self erase anything printed on the surface of special type of paper within a time span of 24 hours, the paper can then be reused for upto 100 times. So you might ask what the use of this? Well it can be used in offices, instead of trashing or recycling the paper, it can be used again and again for upto 100 times. This Reusable paper is environmentally safe, reduces paper waste and could also help in lowering overall paper costs. It is amazing to know that this paper can be used up many times. I never thought of this kind of invention. This is great. How the technology works:

The paper contains specially coded molecules that create a print after being exposed to ultraviolet light emitted from a thin bar in a printer. The molecule readjusts itself within 24 hours to its original form to delete the print, or heat can readjust the molecule instantly. Xerox developed the molecule. The ultraviolet bar itself is very small, so it can also be used in mobile printers.
