Without using words or making noises, tell a story. (This is pantomime/charades. For example, tell the group the following: you are on a flight, and after eating airline food, you get sick. Find a fun way to end the story.)
(I will describe the actions, as I am not able to use visuals or sounds here)
Walk as if you are boarding a plane and sitting down in your seat. Pretend to buckle your seatbelt and adjust your seat. Put your tray table down and pretend to eat from a meal tray. Take a few bites, then start to make a face as if you don't like the taste. Hold your stomach and pretend to groan in pain. Then, start to pretend that you are getting sick, coughing and gagging. Act as if you are frantically searching for a vomit bag, but you can't find one. Finally, in a moment of desperation, you grab the nearest item (perhaps a magazine or blanket) and use it as a makeshift vomit bag. Act as if others around you are horrified, but you feel relieved. With a smile, put the item in the aisle for the flight attendants to clean up. Stand up and act as if you've had enough of this flight and walk off, never to return.
