MATERIALS: Pedestal, water, paper coffee cup, inscription on cup We Are Happy to Serve You.
Optional additional materials: silent wish and coin provided by the public.
Part whishing well, part beggar's cup, and part piggy bank, this humble coffee cup sits on a pedestal. It's cut-out bottom opens into the void of the pedestal. The public may make a wish, throw in a coin, listen to the water swallow the coin, and hope that the transaction proves worthwhile.
