Deprecated because it is dangerous. A player could die attempting this exercise. I hope it is an improv myth.
Head In A Bucket. Bucket of Death.
One player offstage will put their head in an unbreathable plastic bag.
During the scene, one player is always off-stage, with his head inside a dry cleaning bag, slowly suffocating. He is not allowed out of the bag until some other player finds a way to exit the scene and ’liberate’ the suffocating player. New player puts his head into the bag until freed by another player, and first liberated player finds a way to justify his entrance into the scene. Use a bucket of water instead of a dry cleaning bag.
- Tape the bag shut with duct tape and tie the players hands besides their back.
