Shape Sorter:You can freeze desserts in containers of all shapes and sizes. For desserts, we used a store-bought ice-cube mold. But you can use what you've already got in your kitchen: plastic egg cartons, candy molds, paper cones, small Tupperware containers, even mini pie tins.
Note: To help sticks stay in place, cut cardboard squares 1/2" larger than molds. Cut small slit in cardboard to hold pop stick, then push stick through.
