By spearing the water you probably break Newtons third law.
As someone with a PhD in underwater basket weaving, Newton's Third Law is not quite so simple (unless you are swimming in a vacuum). It is usually quoted as To every action there is always an equal and opposite reaction, but that applies to a closed, isolated system. There is more that needs to be accounted for, than just the hand and the small patch of water near the hand.
