Infinite Box
Infinite Box is an object work exercise in which a player mimes opening a box, removing an object, using it, and discovering another box inside, which contains another object, and so on. The exercise trains sustained object work, creativity under repetition, and the ability to generate variety from a single premise.

Related Exercises
Twenty Objects
Twenty Objects is an exercise in which a player must mime twenty different objects in rapid succession, making each one physically distinct and recognizable. The speed prevents overthinking and forces players to commit to their first physical impulse. The exercise builds object work fluency and creative stamina.
Ordinary Object
Ordinary Object is an exercise in which a player picks up a common item and uses it as if it were something else entirely, without explaining the transformation. The audience or group must recognize the new object through the specificity of the performer's handling. The exercise develops object work versatility and the ability to communicate through physical precision.
Group Environment
Group Environment is a space work exercise in which the entire ensemble collaborates to build a shared imagined environment through mime and physical interaction. Each player adds objects, features, and activities that others must acknowledge and use. The exercise trains spatial memory, object permanence, and the foundational skill of creating a believable shared world.
Object Circle
Object Circle is a warm-up exercise in which players pass an imaginary object around a circle, transforming it into something new with each handoff. Each player must clearly establish the new object through mime before passing it on. The exercise develops object work skills and trains the ability to communicate physical reality through gesture alone.
Knife Baby Angry Cat
Knife Baby Angry Cat is a rapid physical transformation warm-up in which participants cycle through three contrasting physical archetypes -- the knife (sharp, linear, precise), the baby (soft, uncoordinated, open), and the angry cat (defensive, arched, volatile) -- on the facilitator's call. The exercise develops physical range, commitment to contrasting states, and the speed of full-body physical transformation.
What's the Object?
What's the Object is an object work exercise in which a performer handles an imaginary item and the group attempts to identify it from the specificity of the mime. The exercise rewards precise physical detail and teaches performers that clear object work communicates powerfully without words.
