We're not exactly sure why more than 40 years passed between the rise of the dry erase marker and dry erase spray paint, but we're not going to look this gift horse in the mouth. Created and patented by a father/son team in Wisconsin, this special formulated aerosol dry erase marker—D.E.P Spray—is going to make the NOAA start naming your brainstorms.
This is perfect for everything: practicing your tags and bubble letters from the safety of your own home, thinking up stuff at the office, or for teachers in schools—though it would probably cause some serious problems if it were used in certain classrooms. With D.E.P Spray, you could even do that ridiculous clear-glass dry erase thing from Numb3rs but with spray paint! Imagine if they had done that. Probably would have saved that show.
