@lonelysandwich made a spec spot for his favorite fastidious and persnickety beverage preparation device here: vimeo.com/40980282
I found it throughly delightful and decided to make one of my own in the same style.
For about $100 you can have a piece of plastic in your kitchen that carbonates water. If you're part of the 1% or something you can add in flavored syrups, but I prefer just the straight up bubbles. When you're out of gas, you can get more carbonators from your local artisanal kitchen store (hi, @hillskitchendc).
I shot this on a 7D and cut it in FCP.
Special Thanks to Roommate Adam S. for helping out with a few things during the shoot.
