Our first show of the calendar year at Triad was Anna Christie. One challenge that arose was the need for a realistic lager beer. The first scene takes place in a bar, and the bartender pours several beers from a keg onstage. We couldn’t use real beer, because the amount the actress had to actually consume would have laid her on the floor before the scene was through. So I needed a self-contained and consistent means to produce several glasses of a fake frothy beverage on a bar which entered at the beginning of the scene and was struck a vista at the end. I shot a little video showing how I did it:
