Making a submarine out of a water bottle is a fun and educational DIY project.
You will need a clear plastic water bottle, a bendy straw, some modeling clay, and a pair of scissors.
This project demonstrates the principle of buoyancy and can both entertain and educate children and adults alike.
To create your water bottle submarine, start by cutting a small piece of modeling clay and sticking it to the bottom of the water bottle to act as a weight.
Next, attach a bendy straw to the cap of the bottle, ensuring that one end of the straw is inside the bottle while the other end sticks out.
When the bottle is submerged in water, the air inside the bottle makes it float.
By blowing into the straw, you increase the amount of air in the bottle, which causes the bottle to rise in the water, simulating the movement of a submarine.
The water bottle submarine is an incredibly easy and fun DIY project that can be used to demonstrate the principle of buoyancy.
When air is blown into the bottle via the straw, the bottle rises in the water, simulating the way a real submarine works.
This project not only provides a visual representation of a complex scientific principle, but also encourages the use of recycled materials in crafting. So why not give it a try and learn some science while

- Stickers or decals: Decorate your submarine with stickers or decals to add personality or replicate real submarine markings.
- Buoyancy materials: Experiment with adding buoyancy to your submarine by using foam or waterproof containers filled with air. This can help the submarine float or submerge to different depths.
Remember, the choice of optional materials depends on your preferences and the purpose of your water bottle submarine. Get creative and have fun customizing your creation!
Making a submarine out of a water bottle is an exciting and enjoyable diy project.
By choosing the right water bottle, gathering the essential tools and supplies, and exploring optional materials for customization, you’ll be well on your way to creating a unique and functional water bottle submarine.
So, let’s dive into this adventure and start gathering the materials you’ll need!
Preparing The Water Bottle
Before you begin building your submarine out of a water bottle, it’s important to properly prepare the bottle to ensure a clean and smooth surface.
This will make the construction process easier and improve the overall appearance of your finished submarine.
Here are the key steps to follow:
Cleaning And Drying The Bottle
Start by thoroughly cleaning the water bottle to remove any dirt, debris, or residue that may be present.
Use warm soapy water and a clean sponge or brush to scrub the entire surface of the bottle. Pay special attention to the inside of the bottle, as well as the bottom and the cap.
After cleaning, rinse the bottle with clean water to remove any soap residue. Make sure to rinse it thoroughly to ensure there is no leftover soap or cleaning solution.
Once the bottle is clean, allow it to air dry completely. This will help prevent any moisture from interfering with the construction process.
You can also use a clean towel to dry the bottle manually if you’re in a hurry.
Removing Labels And Stickers For A Clean Surface
To create a smooth surface for your submarine, it’s important to remove any labels or stickers that may be on the water bottle.
These can interfere with the adhesion of other materials and contribute to an uneven appearance.
Follow these steps to remove labels and stickers effectively:
- Fill a sink or a basin with warm water and add a few drops of dish soap.
- Place the bottle in the soapy water and let it soak for a few minutes. This will help loosen the adhesive.
- Gently scrub the label or sticker with a sponge or a soft brush to remove as much of it as possible. If needed, use a plastic scraper or your fingernails to get rid of stubborn residue.
- Rinse the bottle with clean water to remove any soap residue.
- Dry the bottle thoroughly using a clean towel or by air drying.
By following these steps, you’ll have a clean and label-free water bottle ready for the next stage of constructing your submarine.
Remember, proper preparation of the water bottle is crucial to the success of your submarine project.
Cleaning and drying the bottle and removing labels and stickers will create a smooth and clean surface, ensuring a professional-looking final product.
Assembling The Submarine Mechanism
Creating a propulsion system using a balloon:
- Inflate a balloon with air, ensuring it is not too large for the water bottle’s opening.
- Gently stretch the balloon over the top of the water bottle, making sure it fits securely.
- When ready to propel the submarine, release the air from the balloon, and watch as the force pushes the water bottle forward.
Adding weights for stability and balance:
- Select small weights such as coins or pebbles to maintain stability.
- Carefully drop the selected weights into the water bottle, ensuring an even distribution for better balance.
- Experiment with the number of weights to find the optimal balance and stability for your submarine.
Attaching control fins for maneuverability:
- Cut out thin strips of plastic or sturdy material to serve as control fins.
- Attach the control fins to the outside of the water bottle using strong adhesive or tape.
- Position the control fins strategically, one near the front and the other near the back of the water bottle, to allow for better maneuverability.
Remember, safety is paramount when conducting any experiment involving water or objects that may pose a risk.
Always supervise children and ensure a controlled environment for experimentation.
Now that you’ve assembled your submarine mechanism, it’s time to put it to the test!
Release it in a pool or large basin of water and observe how the propulsion system, weights, and control fins work together to create movement and direction.
Enjoy the thrill of seeing your homemade submarine explore the depths!
