Light the cannabis and slowly pull the smaller bottle upwards out of the water while the bottle fills with smoke. If the bottle doesn’t fill with smoke, you may need to check and make sure that your cap is fully screwed on, and that there are no holes or gaps in the side of the bottle. Any leaks could compromise your gravity bong, and some trial and error may be required before your first successful attempt at a functional device.
You can reuse the foil in your gravity bong. Don’t worry about changing it unless you rip the foil or if the holes get clogged and prevent adequate ventilation, at which point you should swap it out with some new foil.
Once your bottle is filled with smoke, carefully unscrew the cap and put your mouth over the bottle opening.
Use your box cutter to cut the bottom off your smaller bottle. The more of the bottle that remains, the larger the hit you’ll receive, so be careful not to trim too much off the bottom of the bottle.
- Plastic bottle (any size, but 16-20 oz is ideal)
- Bucket or 2-liter plastic bottle
- Aluminum foil
- Box cutter or sharp knife
- Poking device
- Cannabis strains of your choice (at least one gram)
The short answer is yes. Gravity bongs force heavily concentrated smoke into your lungs, filling them to capacity beyond the average hit from a pipe or joint. When you inhale the contents of the smoky bottle into your lungs, you are essentially breathing in the smoke from an entire bowl of cannabis in one go. For this reason, gravity bongs are certainly not for the faint of heart. A tried-and-true method of old school cannabis consumers, it delivers a powerful hit of THC that may be too much for an inexperienced cannabis beginner.
Load cannabis strains of your choice into the foil-wrapped bottle cap, but don’t screw the cap on yet.
Cut the bottom off your larger 2-liter bottle and fill it with water. If you’re using a bucket, fill your bucket with water.
If you’re new to cannabis or have a low tolerance, you probably don’t want to start with a gravity bong. But for intermediate to advanced consumers, making a gravity bong is a fun, easy DIY project that ensures a fast delivery of your favorite strain. Not the crafty type? You can buy gravity bongs to add to your collection of hardware and bust one out whenever you want a unique and potent smoke session.
