Find a pine cone, put it by the fire or a radiator for a couple of days. The pine cone will open up, as it will be tricked into thinking conditions are warm and dry enough for seed dispersal. Tie a piece of wool onto one end of the cone. Little fingers can then squish dried fruit into the cone. Once the cone is full of dried fruit, smear a layer of lard or peanut butter all over the cone. Tie onto a tree and watch the birds enjoy the food.
