Plastic is never an ideal piece of equipment in a process that requires heat, but sometimes we’re left with few choices, and it can work well in a pinch. There are even some things that you can do to reduce the risk, like introducing water to the equation to keep the plastic cooler,  and to help you out, we’re going to explain the three best ways to make a DIY bong with a bottle.

1. The bottle pipe

The bottle pipe isn’t going to offer the smoothest hit on this list, but it also doesn’t require access to clean water, and it’s often the easiest piece to throw together for your first time learning how to make a bong.

You will need:

  • 1 plastic bottle (any size)
  • 1 pair of scissors
  • 1 piece of aluminum foil
  • 1 toothpick


  1. First, thoroughly wash the plastic then pat it dry to ensure that you aren’t inhaling anything that could be hazardous to your lungs.

  2. Create a hole that should be close to the size of a loonie so that it works as the perfect bowl. Use a sharp pair of scissors to carefully remove a small circle of plastic from the lower half of the side of the bottle.

  3. Now, get out your piece of aluminum foil and use your fingertips to mold it into a bowl shape by pressing it gently into the middle of the hole you’ve just cut.

  4. Once you are satisfied with the depth of the bowl, it’s time to give the bong some airflow by using a toothpick to poke several tiny holes into the center of the aluminum foil.

Now, this DIY bong is ready to be used, just pack the bowl with cannabis, remove the cap from the bottle, spark it up, and draw in a long hit through the mouthpiece.

2. The gravity bong

A gravity bong works off the natural forces of the earth’s pull, to draw the thick cloud of cannabis smoke down into the depths on a chamber. The inside of that chamber is filled with water, and as the water empties, the bottle fills up with smoke, and this close contact with a cool liquid helps to provide you with a much smoother hit.

You will need:

  • 1 large plastic bottle
  • 1 small plastic bottle with lid
  • 1 piece of aluminum foil
  • 1 toothpick
  • Water


  1. After washing the containers, you will need to figure out which one will act as the base of your bong, and which one will be the chamber that houses the smoke and rests in the water. Just bear in mind that the bottom will always be made from the largest plastic bottle.

  2. Now, take a sharp pair of scissors and remove the top portion of the largest bottle, just below the line that represents where the label would rest. This should result in the perfect cup shape with sides that aren’t leaning inwards.

  3. Next, you will need to remove the bottom of the smaller bottle. Only a small amount is needed at first, and once it’s gone, set the piece you’ve just cut into the large cup AKA bucket, and from there, trim down the smaller one so that the mouthpiece reaches just a bit above the sides.

  4. The last functional piece that you need to shape is the bowl, which in this case, is housed inside of the smaller bottle cap. Take scissors or a lighter to cut or melt a hole into the middle of the lid. Try to avoid melting the threads, as they will be necessary once it’s time to use this DIY bong.

  5. Take a piece of aluminum foil and gently mold it into a bowl shape before setting it into the hole that you’ve just made in the lid. Fold the edges of aluminum foil around the cap to create the ideal seal, and then use a toothpick to poke a few small holes into the middle of the bowl for airflow.

  • Screw the equipped bowl lid back onto the mouthpiece of the smaller bottle, and then fill the lower portion with cool, clean water approximately ¾ of the way.

  • Push the smaller bottle into the bucket to remove any extra air from the chamber, and just like that, the device is now ready to be used.

  • Pack the bowl, light it up with a heating element, and then once you see that the bud grind is smoldering, slowly and gently pull the smaller bottle upwards, which will slowly empty the chamber as it fills with potent cannabis smoke. Once all the water is gone, you can remove the lid and take the hit by re-submerging the chamber as you inhale from the mouthpiece.

    3. The water bong

    The water bong is a unique hybrid of the two other versions listed above, as it includes water, but doesn’t usually lead to as many spills, thanks to the water staying contained inside of the plastic bottle. This combination offers a supercooled smoke that is easier to take, and much more enjoyable than any dry bongs.

    You will need:

    • 1 plastic bottle (any size)
    • 1 pair of scissors
    • 1 piece of aluminum
    • 1 piece of rubber hose
    • 1 toothpick
    • Hot glue gun
    • Water


    1. The best way to begin is by washing any of the pieces you plan to use on this DIY bong.

    2. Now the easiest way to proceed is to install the hole that will hold the rubber tube first, and much like the first bong, that opening should be located in the lower half of the side of the plastic bottle. Use a pair of scissors and carefully carve away at a hole until the rubber hose fits snugly inside.

    3. Feed the hose into the bottle until the bottom of it rests approximately ½ inch away from the bottom.

    4. Use a hot glue gun to seal up any openings that might allow air to escape around the rubber hose.

    5. Next, you need to build a bowl, and like with the water bong, it’s located in the lid of the container. Use scissors or a lighter to create an opening that is large enough to accommodate a fair-sized bowl.

    6. Now use a small amount of aluminum foil to create an indented bowl in the lid.

    7. Fill the bottle with enough cold water to cover the opening of the rubber hose.

    8. Replace the cap by screwing it into place, and now the device is locked and ready to be loaded up with your favorite strain of cannabis.

    To use this DIY bong, all you need to do is pack the bowl, light it, then take your hit from the rubber hose that sticks out of the side of the bottle. As the smoke travels through a fresh bath of water, it will get cooled down, which is why this is often believed to be the best and most enjoyable way to smoke weed out of a plastic container.
