Sweaty hands will rub out all the urgent details that you doodled, plus no sheet of paper around! How do you go about this? With the Pen+Sprayer, of course! A neat little pen that features a spray on one end. Spray some of the specialized chemical (that turns into a make-shift writing surface) on the palm of your hand and doodle with the pen-end. The message will stay on the impromptu paper till you pull it off.
