A whoopee cushion is one of the oldest prank props in the book. Essentially a rubber cushion filled with air that makes a farting sound when someone sits on it. The whoopee cushion has delighted school children and adults alike since they were invented in the 1930s.
Things You'll Need
Purchase two sheets of thin rubber and glue from your local craft store.
Cut two matching balloon shaped pieces. The shape is basically a circle with a triangle at the bottom.
Glue the rubber together leaving an opening at the bottom for air to escape.
Blow into the opening to inflate the cushion
Place the cushion on an unsuspecting family member’s chair.
Whoopee cushions are widely available at most novelty shops for as little as two dollars. However, it can be a fun project to try to make your own.
