A performance for a group of people

There is a jar, a large glass jar half full of water on the table.
Group of people are standing by the table. One person goes to the window with the jar and pours the water out the open window in silence.
Glass jar is returned to the table and everyone at one’s turn takes the jar and shouts inside the jar in one’s own way. The one who poured the water out the window will shout first in the jar.
Performance is finished when everyone has passed the jar forward to the next one,
till everyone has screamed or shouted in the jar. No words, just noise.
