Did the straw make it easier or harder to breathe?

The straw makes breathing more difficult because it limits the amount of air your mouth can take in. This creates an oxygen debt in your body.

Did you know?

You breathe in 1.5 gallons of air per minute. Imagine how much air the 6+ billion people in the world take in each minute! Plants are our lifesavers since they supply the air with the oxygen we need to live.
