I can’t believe we didn’t try this sooner! Frozen paint popsicles to use on a hot day. I loved how the texture of the paint changed after it was frozen, how pretty it was. I loved the thick texture of it as it melted, which happened fairly quickly in our desert climate (108 on Friday!) My son loves a lot of mess, though, and I don’t think it melted quickly enough for him to dive into the type of mess he prefers when he is using art materials. There are several variations of this online, but I chose to use Dixie cups to freeze mine, sticking in a popsicle stick after about 30 minutes. They needed a warm rinse to come loose from the cups.
