The Straw Experiment

Have you ever tried the classic straw experiment? It’s a fun and simple experiment that demonstrates the power of air pressure. All you need is a straw and a bottle to try it out!

Materials Needed:

• A straw
• A plastic bottle with a lid

Instructions:

1. Fill the bottle with water almost to the top
2. Put the lid on the bottle tightly
3. Take the straw and place it in the bottle, making sure it is completely submerged in the water
4. Now, try to suck the water up through the straw. What happens?

When you try to suck the water up through the straw, you will notice that you are not able to do so. This is because the air pressure inside the bottle is greater than the air pressure outside the bottle. The pressure inside the bottle pushes the water up the straw, preventing you from being able to suck it up.

Why It’s Fun:

The straw experiment is not only educational, but it’s also a fun and entertaining way to learn about air pressure. It’s a great way to demonstrate a basic scientific principle in a hands-on way. Plus, it’s a great way to impress your friends with your science knowledge!

So grab a straw and a bottle and give the straw experiment a try. You’ll be amazed at what you can learn from such a simple and fun experiment!
