How to Assemble a Whoopee Cushion
- 1). Purchase craft glue and two thin sheets of rubber that are less than 1 foot square.
- 2). Place both rubber sheets together. Cut the sheets to resemble a rounded pillow or a balloon, leaving a small rectangular opening on one end to blow up the device.
- 3). Glue the edges of the rubber sheets together to seal up the cushion, keeping open the air opening.
- 4). Inflate the whoopee cushion to try it out after the glue has dried. Use more glue in the air opening to make it smaller, if the whoopee cushion doesn't make the correct sound.
