The water gravity trick is a fun and simple experiment that will surely impress your friends and family. With just a few materials, you can make it seem like water is defying gravity and flowing upwards instead of downwards. In this article, we will guide you through the steps on how to do the water gravity trick.
Materials
- A clear glass or plastic container
- A small piece of cardboard or plastic
- Water
- Food coloring (optional)
Instructions
- Fill the container with water, leaving a little bit of space at the top.
- Add a few drops of food coloring if desired.
- Place the cardboard or plastic over the top of the container, making sure it is completely covered.
- Hold the cardboard or plastic in place and flip the container over so that the opening is facing downwards.
- Slowly remove your hand from the cardboard or plastic, making sure it stays in place.
- Watch as the water stays in the container, seemingly defying gravity and flowing upwards towards the cardboard or plastic.
Explanation
The water gravity trick works because of air pressure. When the container is flipped over, the air pressure inside the container becomes greater than the air pressure outside of it. This increased pressure pushes against the cardboard or plastic, creating a seal that prevents the water from escaping.
When the cardboard or plastic is gradually removed, the air pressure inside the container remains greater than the air pressure outside of it. This causes the water to flow upwards towards the opening where the cardboard or plastic was removed, creating the illusion of water flowing against gravity.
Tips
- Make sure the cardboard or plastic covers the top of the container completely to create a tight seal.
- Slowly remove your hand from the cardboard or plastic to avoid disturbing the air pressure inside the container.
- Experiment with different sizes and shapes of containers to see if the trick still works.
- Add food coloring to the water to make the trick more visually appealing.
Conclusion
The water gravity trick is an easy and impressive experiment that you can do at home with just a few materials. By understanding the science behind air pressure, you can create the illusion of water defying gravity and flowing upwards. With a little practice, you can amaze your friends and family with this fun trick.

FAQs – How To Do The Water Gravity Trick?
1. What materials do I need to perform the water gravity trick?
The water gravity trick only requires a glass of water, a piece of cardboard or paper, and a coin or small object.
2. How does the water gravity trick work?
The trick works by using the properties of air pressure. When you place the cardboard or paper over the glass of water and turn it upside down, the air pressure inside the glass decreases. This causes the water to stay in the glass even when it is upside down. The coin or small object on top of the cardboard helps to seal the opening and prevent air from entering the glass.
3. Is the water gravity trick safe to perform?
Yes, the water gravity trick is safe to perform as long as you are careful and follow the instructions correctly. Make sure to use a sturdy glass and hold it securely when you turn it upside down. Also, make sure to place the cardboard or paper tightly against the mouth of the glass to prevent any water from escaping.
