+title: Fishbowl Discussion
+description: >-
+  A format for productive conversation in large groups, where a small
+  inner circle discusses while an outer circle observes.

+steps:
+  - headline: Set up the circles
+    description: >-
+      Arrange 4-6 chairs in an inner circle for discussants. The rest of
+      the group sits in an outer circle around them.
+  - headline: Begin the discussion
+    description: >-
+      The inner circle discusses the topic. Only people in the inner
+      circle may speak.
+  - headline: Rotate seats
+    description: >-
+      One chair is left empty. Anyone from the outer circle can tap a
+      discussant and take their seat. The displaced person joins the
+      outer circle.
+  - headline: Debrief together
+    description: >-
+      After the discussion, the full group reflects on what was said and
+      what patterns they noticed in the conversation.
+outcome: >-
+  A focused, in-depth discussion happens without the chaos of a
+  full-group free-for-all. More voices contribute than in a panel
+  format.
+practice: >-
+  Set a minimum time before rotation (2-3 minutes) so discussants can
+  make a point before being tapped. Brief the outer circle to listen
+  for themes.
