Get an empty lipstick or chapstick type container. A)Force feed small quantities at a time down the pipe, or B)Using a pair of pliers, take a soup size can and create a 'v' shaped notch on the circumference. On the opposite edge make an lip to grip. Place some wax in this container and place the container it in a pot of boiling water. Make sure the flame is low so the water is barely bubbling. When the wax is melted, turn off the flame and carefully pout the wax into the pipe of the container. Allow to dry.
