Fast forward to 20:50 where you see the racers at a store then to the 21:00 minutes point where you see them with lots of bottles. For fun, watch the guy trying to open a bottle by using a recessed Allen bolt stem at 22:03 on.

For more fun check out the mechanic adjusting the rear derailleur at 32:35.
