I reacted by flinching when the ball of paper was thrown at me. This would have protected me if the sheet wasn't there because I would have ducked to avoid getting hit. In a previous science project we had to catch rulers to test our muscle memory.

In this experiment we had to see how our nerves reacted when the paper ball was thrown and humans natural flinch or try to avoid the ball or thing to protect themselves. This reflex is called
