Once your bottle is filled with smoke, carefully unscrew the cap and put your mouth over the bottle opening.
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.
Research is still being conducted on what sort of impact this type of exposure may have on your health. Many cannabis consumers prefer to use glass or silicone smoking devices and avoid plastic as a precaution. If you choose to make homemade gravity bongs and other smoking devices out of plastic materials, be aware of the risks and proceed with caution.
Unscrew the cap to your smaller bottle and use your box cutter or scissors to make a hole in the bottle cap. It should be big enough to draw air through, but not so big that the foil (and cannabis) will fall through into the water.
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.
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)
However, if you’re looking for a bit of nostalgia and feel like getting crafty with your cannabis consumption, here’s a handy guide to creating your own gravity bong using a few everyday household objects. (Disclaimer: Inhaling combustible materials from a plastic smoking device may be hazardous to your health. Proceed at your own discretion!)
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.
