In this video, we provide our octopus with a twist top bottle that contains a delicious snack. The bottle has a small opening that allows him to get one of his arms through the hole in order to touch and taste the fish. However, due to the small size of the opening, the octopus is unable to pull the fish through. The only way he can access his food is to unscrew the top of the bottle. He was able to find another way into the bottle that was not foreseen by his handlers. It’s always fun when an experiment takes a turn we did not expect. In order to understand the force applied to pop off the white top, we tried to replicate this ourselves. We were able to pop the top off outside of the tank, but when the bottle was inside the tank, we were unable to duplicate what the octopus did. We applied a tremendous amount of force and we were still unable to do what he did inside the water.
