Put glue on the outside of paper towel roll. You can use sponges or paint brushes to evenly coat the whole tube. Lay birdseed out on the table and roll the paper towel roll over it until it is evenly coated all the way around. Have an adult punch holes on both ends of the paper towel roll and then use string or yarn to make a hanger. Hang on a tree. You can also use peanut butter as the glue.
