We did this awhile ago when we did Corn Syrup painting the first time so I decided to introduce this again. The Artful Parent calls it Puffy Paint. He loved it! I didn't mix it very well because chunks of flour or something kept getting stuck in the nozzles. (another thrift store find!) I saved it over the weekend in the refrigerator and he painted again with it today. We just stirred it back up and it was as good as new.
