Knife Throwing
Knife Throwing is an object work and shared reality exercise in which one performer mimes throwing a knife -- or another specific object -- and a partner mimes catching it, with both performers committed to the same imaginary object's weight, speed, and trajectory. The exercise trains precise physical negotiation of shared imaginary objects and the two-performer coordination required for shared object work.
Structure
Setup
Participants stand in pairs facing each other at a distance of several feet. The facilitator establishes the object: a throwing knife, with agreed weight, length, and balance.
Progression
One performer mimes picking up and gripping the knife, establishing its weight and size. The performer then throws it with full physical commitment -- an arm swing that communicates speed, rotation, and trajectory. The catching partner must receive the throw as if catching the same object: tracking its path, adjusting to its speed, and landing the grip where the throw placed the handle.
Partners exchange roles and throw. The facilitator coaches precision and physical commitment: the throw and catch must agree on the object's speed, weight, and arc.
Conclusion
The exercise concludes when partners have developed consistent physical agreement on the imaginary object and can sustain that agreement across multiple exchanges without losing shared specificity.
How to Teach It
Objectives
Knife Throwing targets precision in object work and the ability to establish and maintain a shared physical reality with a partner. It trains the discipline of genuine physical specificity rather than gestural approximation.
How to Explain It
"The knife exists. It has weight, it has a handle, it rotates in the air. When you throw it, commit to what your body knows about throwing something real. When you catch it, track what the throw told you: how fast, where it's spinning, where the handle is going to be. Both of you have to be agreeing on the same object."
Scaffolding
Begin with slow, deliberate throws before increasing speed. Have the catcher describe the object they received after each throw -- the description should match what the thrower intended. Use this as a calibration tool before continuing.
Common Pitfalls
The throw is often performed as a mime gesture without genuine physical investment, resulting in a vague arc that gives the catcher no information. The exercise requires the thrower to commit fully to the physical act of throwing, generating real information that the catcher can track and respond to.

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.
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.
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.
Blind Run
Blind Run is a trust exercise in which one player closes their eyes and runs across the room while a partner ensures their safety. The exercise confronts the fear of surrendering control and builds deep trust between partners. It requires careful facilitation and a safe physical environment.
Tug-O-War
Tug-O-War is a group exercise in which two teams mime pulling on opposite ends of an imaginary rope, coordinating their movements to create the illusion of genuine physical struggle. The exercise trains ensemble physicality and the ability to create a believable shared object through synchronized effort.
Blind Lead
Blind Lead is a classic trust exercise in which one player closes their eyes while a partner guides them through the space using touch or voice. The exercise builds trust, communication, and sensitivity to a partner's needs. It is foundational to many physical and ensemble-building curricula.
