Things You'll Need
Instructions
Use hole punch to punch a hole in side of tube 3/4-inch from opening on one end.
Cut a piece of wax paper to measure 5-by-5 inches.
Lay the wax paper square on a flat surface. Place the open end of the cardboard tube where you punched the hole on top of the wax paper square.
Fold the ends of the wax paper over the outer sides of the cardboard tube. Pull the paper tight across the opening of the tube.
Wrap a rubber band around the outside of the wax paper to secure it to the cardboard tube. The rubber band should be tight but not bend the tube. Push or trim back any wax paper that covers the hole you punched on the side of the tube.
Hum through the open end of the cardboard tube making fast short tones. The wax paper will vibrate when air passes through the hole and create a sound replicating that of a goose.
