Announce opening at a semi-traditional art gallery of a piece called "Opening."
Serve an ocean of wine as well as one thousand small pieces of cheese impaled on one thousand toothpicks.
Soak one of the toothpicks in LSD. (Depending on the venue, LSD may be a lemon saline dilution, licorice sugar dye, light salad detergent, et cetera.)
Watch who gets the selected toothpick.
