Quick ideation on bells and whistles
How to indicate time is up:
1. bell master
2. several bell masters; all with timers
3. set expectations ahead of time – perhaps name is best at first
4. set challenges by table
5. use different methods at each table (bell, time card, silent indicators).
6. use the secret weapons – Moe the Clown, the hook
As always, get out there, be visible, and be creative!
