Goal: everyone stands in order — 1 Jan to 31 Dec — no talking, no writing.
Only gestures, pointing, fingers, eyebrows. 90 seconds on the clock.
Then check: did everyone say their birthday out loud to verify the order?
Teams coordinate with gestures when words are gone
How much did you manage without a single word? Here's what the silence proves: a team doesn't run on talking — it runs on signals everyone already understands. Pointing, eyebrows, held-up fingers. Teams in loud factories, submarines, and basketball courts all run on exactly this.
The trap you just dodged is the over-talk trap: when everyone speaks at once, less gets decided than when nobody speaks at all. Gestures force you to actually watch each other.
