If you have already mastered the plastic pop bottle gravity bong, then this next homemade bong should be a breeze. It’s almost fall and the temperatures are dropping, there is no way to deny that fall is almost here, and my favorite part about this season is Halloween. There is nothing better than a good reason to dress up, and take a step out of reality, even if it's just for one night a year, and this is it. Now that we are grown, trick or treating is out of the question, but we can still throw the biggest cannabis-themed Halloween bash on the block.

Whether you are looking, for the perfect entertainment piece for friends, project for a competition, centerpiece for a party, or simply a DIY project with pumpkins, then this homemade bong is perfect. Simple for beginners, and incredibly easy to personalize by decorating the shell using almost anything you might find laying around the house, alongside a bit of imagination and glue.

How to make a pumpkin bong for Halloween

This spooky bong is perfect for Halloween or any other fall season activity where the adults might want to partake in something a bit different. Any color of pumpkin can work, and sometimes it can add an extra effect like using white ones for ghosts, or orange ones for a traditional jack-o-lantern.

You will need:

  • 1 pumpkin with a flat bottom to prevent from tilting (any size or color, but should be larger than the circumference of the plastic bottle)
  • 1 plastic bottle with lid
  • 1 shark carving knife
  • 1 large scoop (or spoon)
  • 1 large bowl
  • 1 black marker (for tracing features)
  • Scissors
  • Aluminum foil (or bong stem with screen)
  • Water

Other decorative materials (choose any that you like)

  • Markers
  • Paint
  • Pens
  • Stickers
  • Stencils


  1. Place a pumpkin flat on the bottom and then mark out the size for the perfect holes. This can be done by visually assessing the portion surrounding the stem alongside the plastic bottle. Since the container will need to fit inside of the pumpkin, the hole that you trace with a black marker should be larger than the width of the bottle.

  2. Use a very sharp knife to carefully carve out a lid, by pressing the tip of the blade inwards on a slight angle, to create a lip for the lid to rest. This makes it so that the pumpkin bong can be used as decoration outside for a week or two by cutting out some of the features and replacing the water inside with a flickering tealight candle.

  3. Take a scoop or large spoon and scrape the insides out of the pumpkin. Everything needs to be removed, so keep going until all walls of the pumpkin are well exposed, and there are no remaining seeds or pieces. The pumpkin guts can be placed into a large bowl and saved to make baked pumpkin seeds for later when the munchies kick in.

  4. Once you are certain that all of the insides have been removed, rinse out the pumpkin shell to avoid any floaties in your bong water.

  5. It is time to move onto the decorating, and there is no right or wrong way to do this. Leave the pumpkin completely plain or trace out some creepy features using whatever materials you have on hand. Technically, you could do this anytime, but completing it now ensures plenty of time to let the decorations set and or dry.

  6. The chamber will consist of a simple yet functional design that is easy to make. Take the bottle and remove the base with scissors and rest in the inside of the pumpkin shell to ensure it stands upright. If you find that it tips, you may have to make some adjustments to the base by scraping away a bit more of the pumpkin’s fruit.

  7. Now, install a bowl by cutting or melting a hole into the lid of the pop bottle that is large enough for the bong stem to fit snugly inside, or suitable for making a bowl with some aluminum foil. This can be done by removing the lid and using scissors, but the tip of a flame from a lighter or torch is often easier.

  8. If you used a bong stem, then you will need to install a screen. However, if you opted for foil instead, you will have to wrap the lid and shape a divot for a bowl, then take a small pin or toothpick to poke breathing holes into the bottom center of it.

  9. It is now time to fill the pumpkin with water to finish off this functional gravity bong. Once done, remove the lid and slowly set the container base opening first into the cold-water chamber.

  • Replace the lid, and your homemade bong is ready to be packed loaded and used.

  • Cannabutter pumpkin seeds recipe

    Wondering what to do with your freshly harvested pumpkin seeds? Well, look no further. This cannabutter pumpkin seeds recipe will keep you glowing all night long and takes minimal time and skill to prepare.


    • 1 cup of pumpkin seeds
    • 2 teaspoons of cannabutter
    • Salt (to taste)


    • Baking pan
    • Spatula
    • Large bowl
    • Strainer
    • Mixing spoon
    • Paper towels
    • Oven


    1. Preheat the oven to 300°F.

    2. Use a strainer and hot water to wash away any remaining pumpkin fruit materials and wait for them to dry before proceeding. Speed up the drying process by resting the pile on paper towels and patting them.

    3. Once the moisture has been removed, add all the seeds to a large bowl, and drizzle softened cannabutter on top. If your cannabutter is still hard, then it can be liquified to make spreading it easier, by microwaving the mixture on high in 30 second intervals.

    4. Add in the salt and combine the ingredients well until the seeds are evenly coated.

    5. Scatter the pumpkin seeds on a baking pan and bake them in the oven for 45-50 minutes while flipping them on occasion to avoid scalding.
