coolwhip,food coloring,heavy paper
mix a food coloring and coolwhip together to make desired color. not to much food coloring or it will be too runny. make sure you do not stir to much or the coolwhip will break down. give to your toddler along with a piece of paper and let he/she create with thier hands, paint brush, anything really. when it dries flat on a table you have the most creative 3-d picture.
