How it Works:
Your thumb will trap air inside the straw. By trapping the air, the air molecules will compress and give your straw strength that keeps it from bending as you stab it through the potato.
Make This A Science Project:
Try this experiment with different sized straws. Try this experiment with other vegetables and fruits.
