To teach ants to spell out words on the driveway, first write out the letters with sugar syrup. The ants congregate on the syrup and form the word. I think that at first they don't get it, really. But with positive reinforcement and coaching, pretty soon when the ants see you coming with the syrup, they start spelling out words they already know. I have one ant team up to 41 words already. They seem to like profanity best for some reason.
