Bring anything but a cup

 Ever wondered what we would do if the glass had never been invented? Would we drink out of plastic bags, salad bowls, or even watering cans? To test which containers would work or might even be better than beer glasses or cups, bring your waterproof container that is NOT A CUP OR GLASS and get your first fill for free (0.5 liters). Bring the most creative container and win a prize!
