So, you want to know how to make a potato gun, huh? Well, you've come to the right place! Making a potato gun can be a fun and rewarding project for any DIY enthusiast. Whether you're looking for a new backyard toy or just want to impress your friends with your homemade engineering skills, building a potato gun can be a blast (pun intended). In this article, we'll walk you through the process of making your very own potato gun from scratch. So, grab your safety goggles and let's get started!


Materials Needed

To build your very own potato gun, you'll need a few basic materials that can be easily found at your local hardware store or online. Here's a list of what you'll need:

  • PVC pipe: Look for a 2-inch diameter PVC pipe, which will serve as the main body of your potato gun.
  • PVC end cap: You'll need an end cap that fits snugly onto the PVC pipe to seal one end of the gun.
  • PVC reducer coupling: This will allow you to connect the smaller PVC pipe that serves as the barrel to the larger PVC pipe.
  • Ignition source: You can use a simple BBQ igniter or a lantern sparker to ignite the fuel inside the potato gun.
  • Aerosol spray: A can of aerosol spray, such as hair spray or deodorant, will serve as the fuel for your potato gun.
  • Potatoes: Of course, you can't forget the star of the show – the potatoes! These will be the projectiles for your potato gun.

Once you have all these materials gathered, you'll be ready to move on to the next step of building your potato gun.


Building the Potato Gun

Now that you have all the necessary materials, it's time to roll up your sleeves and start building your potato gun. Follow these steps to bring your potato gun to life:

  1. Prepare the PVC Pipe: Begin by cutting the 2-inch PVC pipe to your desired length, typically around 2-3 feet. This will serve as the main body of your potato gun.

  2. Attach the Reducer Coupling: Next, attach the PVC reducer coupling to the open end of the main PVC pipe. This will serve as the connection point for the barrel of the potato gun.

  3. Create the Barrel: Take the smaller PVC pipe and insert it into the reducer coupling. This will serve as the barrel of your potato gun. Make sure it fits snugly to avoid any air leakage.

  4. Seal the End: Use the PVC end cap to seal the open end of the main PVC pipe. This will ensure that the fuel and projectile stay contained within the potato gun until it's ready to be fired.

  5. Add the Ignition Source: Drill a small hole near the rear of the potato gun to insert the ignition source, such as a BBQ igniter or a lantern sparker. Make sure it's securely in place.

  6. Load the Fuel and Projectile: Before testing your potato gun, spray a small amount of aerosol spray into the barrel and insert a potato as the projectile. Be sure not to overfill the barrel with fuel.

  7. Test Fire: With safety goggles on and pointing the potato gun in a safe direction, press the ignition source to release the fuel and ignite it. The force will propel the potato out of the barrel.

By following these steps, you'll have successfully built your very own potato gun ready for some outdoor fun.


Testing and Using the Potato Gun

After you've built your potato gun, it's time to put it to the test and have some fun with it. Here's how you can safely and effectively test and use your newly constructed potato gun:

  1. Safety First: Before anything else, always prioritize safety. Make sure to wear safety goggles to protect your eyes during the testing and firing of the potato gun. Additionally, ensure that you are in an open outdoor space away from people, animals, and property.

  2. Aim and Fire: Once you're in a safe outdoor area, take aim at a clear target and load the potato gun with the aerosol spray and a potato projectile. With the potato gun pointed away from anyone or anything valuable, press the ignition source to release the fuel and ignite it. The force generated will propel the potato out of the barrel towards your target.

  3. Adjust and Experiment: As you test the potato gun, take note of the distance and accuracy of your shots. You can experiment with different amounts of fuel and projectile sizes to see how they affect the performance of the potato gun. This trial and error process can be both educational and entertaining.

  4. Have Fun Responsibly: While using your potato gun, always be mindful of your surroundings and the potential risks. Avoid aiming the potato gun at living creatures, including animals and people, and never use it in a manner that could cause harm or damage. Remember, the primary goal is to have fun in a safe and responsible manner.

By following these steps, you can enjoy the fruits of your labor and have a great time using your homemade potato gun. Just remember to always prioritize safety and be mindful of the potential risks associated with operating such a device.


Safety Precautions

When it comes to any DIY project, safety should always be the top priority, and building and using a potato gun is no exception. Here are some essential safety precautions to keep in mind:

  • Wear Safety Gear: Before you even think about testing or using your potato gun, make sure to put on a pair of safety goggles. Protecting your eyes from any potential debris or fuel spray is crucial for your safety.

  • Choose the Right Location: Always operate your potato gun in an open outdoor area away from people, animals, and property. This will minimize the risk of any accidents or damage caused by the projectile.

  • Handle with Care: Treat your potato gun with the respect it deserves. Avoid dropping or mishandling it, especially when it's loaded with fuel and ready to fire.

  • Use the Right Amount of Fuel: It's important not to overfill the barrel with aerosol spray. Using excessive fuel can lead to an unpredictable and potentially dangerous release of energy when ignited.

  • Mind Your Aim: Never aim the potato gun at living creatures, including animals and people. Always direct the potato gun towards a safe and clear target, ensuring that no one is in the line of fire.

  • Supervise and Educate: If you're sharing the potato gun experience with others, especially younger individuals, take the time to educate them about the potential risks and the importance of safety measures. Always supervise and guide them through the process.

By adhering to these safety precautions, you can enjoy the process of building and using your potato gun while minimizing the risk of accidents or harm to yourself and others. Remember, safety first, fun second!



Congratulations! You've successfully learned how to make a potato gun from scratch. By following the steps outlined in this guide, you've transformed basic PVC pipes and a few other materials into a fun and entertaining DIY project. From gathering the necessary materials to building, testing, and using your potato gun, you've embarked on a journey that combines creativity, engineering, and outdoor enjoyment.

As you venture into the world of potato gun creation, always remember to prioritize safety. Whether you're building, testing, or using your potato gun, safety measures should never be overlooked. By wearing safety goggles, choosing the right location, handling the potato gun with care, and being mindful of your aim, you can ensure a safe and enjoyable experience for yourself and those around you.
