Feeding during open water swimming can be accomplished by grabbing a pre-opened bottle from a kayak, chugging it, and dropping it within approximately seven seconds while maintaining swimming motion.

“if the kayaks on your left when your right arm is in front you arch over and you with your left hand grab a bottle that's on a carabiner on a rope and you flip on your back the bottle is already opened you chug it and drop it and rotate and keep swimming and it should take about seven seconds to do that”
