Do you think that you can get a regular drinking straw to go through a hard raw potato? It doesn’t seem possible does it.
Well today, we are going to test our strength by attempting to put a put a straw through a potato. It may sound impossible, but with a little scientific “magic” I’m going to show you how it can easily be done.
How to Put a Straw Through a Potato Science Experiment Video
- Drinking Straw
Step 1 – First, prepare your straw. If you have a straw that has a bendable top, cut off the top portion of the straw so you are left with a section that isn’t bendable.
Step 2 – Next, attempt to stab the potato with the straw. You will likely get the straw to pierce the skin of the potato, but it will not go into the potato very far.
Step 3 – On your second attempt, place your thumb over the far end of the straw.
Step 4 – Then stab the potato with the straw again.
Step 5 – This time, with no more effort than before the straw will sink deep within the potato. You may even get it to go completely through the potato.
How Does the Science Experiment Work?
Air pressure is the secret to this experiment.
On your first attempt to stab the potato with the straw, the air inside the straw was pushed out of the top of the straw when it came into contact with the potato. As a result the straw
On your second attempt to stab the potato with the straw, the air inside the straw was trapped because your thumb was covering the top of the straw. Because of this, the compressed air inside the straw made it strong enough to go through the potato.
I hope you enjoyed the experiment. Here’s some printable instructions.
