All you need for this craft is water biodegradable packing peanuts. These packing peanuts dissolve in water. You will use the packing peanuts and by dabbing your finger in water and lightly rubbing the end of two packing peanuts, you can get them to stick together without fully dissolving. If you would like to sculpt animals or figures, you may want to add details with markers. Have fun!! If you want to make your sculpture disappear, just add water!
