Ask every person who wants to participate to pick up a chair.

Have them move all chairs together so that they nearly touch at one corner.

Put a book, a sheet of paper or another unbreakable object into the middle, so that it is supported by each of the chairs.

Now ask the participating people to slowly pull out their chair. Let them do it one by one, not all at the same time.

After most of the chairs are gone, as the next chair goes out, have them watch the book drop to the floor.

Repeat the drill, but now use a piece of paper on which you have written a thing that all of you who participate in the drill really don't like in your society. Have a look at some social habits and some cultural patterns to get an idea about what to write onto the paper, but use an item that is known to all of you from your own life.

As the participating people pull out their chairs under the paper, ask them to get the idea that it is their support they are pulling back from underneath the cultural pattern they do not like - not just a wooden chair from underneath a piece of paper.

Discuss the exercise with the people who have participated until they feel good about it or have some new insights.
