Colored Jello Fun
Ice cube tray, food coloring, clear gelatin
Follow the directions to create clear gelatin (Knox is a common brand). Then fill up an ice tray with the clear gelatin liquid and put a few drops of different food coloring liquid in each cup. Cool according to the package directions. Once the gelatin has cooled, put one or several 'cubes' into a clear plastic bag and seal with duct tape. Your kids will have a ton of fun squishing around the cubes in the bags. This is also a great way to teach colors names and color blending!
