Gently push the bottle back into the water. As the water enters the bottle, the smoke will be pushed into your lungs.
Once your bottle is filled with smoke, carefully unscrew the cap and put your mouth over the bottle opening.
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.
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.
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!)
First, gather the following items:
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.
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.
Wrap the cap in aluminum foil, shaping the foil to create a small “bowl” divot for your cannabis. You can shape the bowl to be as deep as you’d like, and the foil will keep your cannabis from falling into the water below. You may need to cut off excess foil and shape it to avoid spilling cannabis. Health hack: if you’re looking to spare your lungs, try this metal bowl piece specifically designed to be used for gravity bongs.
