How to Make a Gravity Bong DIY

A gravity bong is a simple but effective way to smoke your favorite herb or tobacco. It uses two empty plastic bottles and some water to create a vacuum that pulls the smoke into your lungs. You can make a gravity bong at home in just 10 minutes with some common household items. Here’s how:

What You’ll Need

  • An empty plastic bottle (any size, but bigger bottles produce bigger hits)
  • Another plastic bottle or container that is larger than the first one
  • A pair of scissors or a knife
  • Aluminum foil
  • A toothpick, a pin or a paper clip
  • Your herb or tobacco of choice
  • A lighter

Step 1: Make the Bowl

  1. Cut off the bottom of the smaller bottle with scissors or a knife. You can discard the bottom part or recycle it.
  2. Unscrew the cap from the bottle and make a hole in the center of it with your scissors, knife, pin or paper clip. The hole should be big enough to fit your finger.
  3. Tear off a piece of aluminum foil and wrap it around the cap, covering the hole. Press the foil down gently to make a bowl shape.
  4. Poke some small holes in the foil with your toothpick, pin or paper clip. Don’t make too many holes or too big, or your herb or tobacco will fall through.
  5. Fill the bowl with your herb or tobacco, but don’t pack it too tight.

Step 2: Make the Bong

  1. Fill the larger bottle or container with water, leaving some space at the top.
  2. Place the smaller bottle inside the larger one, making sure that the mouthpiece is above the water level.
  3. Screw the cap with the bowl back on the smaller bottle.

Step 3: Use the Bong

  1. Light up your herb or tobacco with your lighter and slowly lift the smaller bottle out of the water. This will create a suction that will draw the smoke into the bottle. Don’t lift it too high or it will come out of the water and lose the vacuum.
  2. When the bottle is full of smoke, unscrew the cap and put your mouth over the mouthpiece.
  3. Push the bottle back into the water while inhaling the smoke. This will force the smoke into your lungs. Be careful not to inhale too much or too fast, as gravity bongs can produce very potent hits.
  4. Enjoy!

You can also make a waterfall gravity bong, which is similar to a regular gravity bong but uses only one bottle and no water container. To make a waterfall gravity bong, follow these steps:

  1. Cut a small hole at the bottom of an empty plastic bottle.
  2. Cover the hole with your finger and fill the bottle with water.
  3. Make a bowl out of aluminum foil and poke some holes in it.
  4. Screw the bowl on top of the bottle and fill it with your herb or tobacco.
  5. Light up your herb or tobacco and remove your finger from the hole at the bottom of the bottle.
  6. The water will drain out of the bottle and create a vacuum that will pull the smoke into it.
  7. When all the water is gone, unscrew the cap and inhale the smoke from the bottle.

A gravity bong is a fun and easy way to enjoy your herb or tobacco. It’s also very cheap and eco-friendly, as you can reuse your bottles and foil. Just make sure you use it in a place where smoking is legal and safe. Happy smoking!
