Today at the little afternoon arts and crafts class that I teach every Wednesday we painted with ice cubes and it was tons of fun. I just used a little food coloring and water and froze it in an ice cube tray and added Popsicle stick halves for gripping. They worked best during the first half hour when they were still pretty frozen but the colors dulled quite a bit as they melted. It was still a ton of fun. A great summer craft for sure!
