Toddler Mud If you add about 1/4 cup wallpaper paste to this mixture, the children can make something to keep. The wallpaper paste will allow it to harden. 4 rolls toilet paper 3 cups Ivory Snow 1 gallon warm water Let toddlers help unroll the toilet paper. Mix soap and water together in a bucket. Add toilet paper, and allow paper to absorb the soap mixture. This mixture keeps at least one month. You can color this mixture by using colored toilet paper or by using food coloring (color the water prior to adding the toilet paper).
