Puffing Power

Today in science we learned how we can use our breath to create a pushing force.  We experimented with straws of two sizes and found that air is able to have a faster push on our ping pong balls when the straw is narrower.  We found that wider straws do not allow our air to move as fast.  We also experimented with how changing the direction of our air can push or pull our ball in different directions.
