How do you make homemade washable paint? When I taught pre-school there was something we would add to tempera paint that was not washable that made it washable but I can't remember what it was!
I never even knew about this so when you find the answer please let me know. Something like this would come in handy with our household, I can turn into any wall and see marks of something or another on them.
