Install a pop up ice rink throughout the entire ground level of a gallery.
Invite visitors to come for a skate as a novel way of looking at the art, the marketing department will love the idea, something for the festive season perhaps?
One day the electricity is cut off because someone’s hacked the IT systems and the gallery hasn’t paid any bills for months.
The ice melts and destroys the floor of the gallery, the walls are wrecked, the art is ruined, the gallery closes.
Then they realize there’s no insurance.
It’s over for the gallery.
