Now is the time to reveal the secret to the “Straw Through Potato” experiment.
If you look back at the pictures you will notice that every time I tried to put the flimsy straw through the dense potato, I had my thumb firmly covering the top of the straw. Because of this, the air could not escape. That means as the straw went thought the potato, the air inside compressed. As a result, the air pushed against the sides of the straw making the straw an instant Superman! What does that make the potato?
