To prove it, it is simple. In the episode "It came from goo lagoon", Krabs gave him a bottle with the "formula". After Plankton opened the bottle and looked on that paper, he saw that a dynamite was attached to it. In real life, that's not possible, because you can't lit a dynamite while being underwater. Is there something else that stops Plankton from stealing it ? Am I wrong ? Discuss.
