CAN YOU PUNCH A HOLE THROUGH A POTATO USING ONLY A STRAW?
To try to punch a hole in a potato using only a drinking straw
HOW DOES IT WORK?
Covering the top of the straw with your thumb traps air inside, forcing it to compress as you stab the straw through the potato skin. This creates enough rigidity within the straw to pierce the potato.
