How To Make Your Own Gravity Bong?

The gravity bong is pure stoner genius. Of all the different ways to smoke weed, the gravity bong is one of the most novel methods ever invented. Is it the best way to smoke weed? Probably not, but talk about stoner ingenuity, right.

The gravity bong is famous for two things—getting dudes hella high using ordinary household objects and doing so with minimal amounts of bud. Want to learn how to make a gravity bong?

A gravity bong is a method of consuming smokable substances such as cannabis. The term describes both a bucket bong and a waterfall bong, since both use air pressure and water to draw smoke.

The bucket bong is made out of two containers, with the larger, open top container filled with water. The smaller has an attached bowl and open bottom, and the smaller is placed into the larger. Once the bowl is lit, the operator must move the small container up, causing a pressure difference. Smoke slowly fills the small jar until the user removes the bowl and inhales the contents. A waterfall bong is made up of only one container. The container must have a bowl and a small hole near the base so the water can drain easily. As the water flows out of the container, air is forced through the bowl and causes the substance to burn and accumulate smoke in the bong.

Do gravity bongs get you higher? 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.

Making the Bowl

Find an empty plastic bottle. An empty water bottle or liter of soda will work. You can use any size bottle, but keep in mind that the bigger the bottle, the bigger the gravity bong hits will be.
If you’re smoking alone, a small plastic bottle should work. You may want a large plastic bottle if you’re smoking with multiple people.
Make sure the bottle you use can fit inside a second, larger plastic bottle or a bucket.

Take off the cap and cover the mouthpiece with aluminum foil. Don’t wrap the aluminum foil around the mouthpiece too tightly. You’ll need to take it off later when you’re smoking out of the gravity bong. The entire opening should be covered with the aluminum foil.

Poke tiny holes in the aluminum foil over the mouthpiece. Use something thin to make the holes, like a toothpick or the end of a paper clip. Don’t make too many holes or make the holes too big or the cannabis will fall down into the gravity bong. You just need a few holes so the smoke from the cannabis can travel down into the bottle.

Making the Bong

Cut the bottom off the empty plastic bottle. First, gently pierce the bottle with a knife around 1–2 inches (2.5–5.1 cm) from the bottom. Then, insert a pair of scissors into the slit you made and cut around the bottle in a straight line until the bottom comes off. Set the top of the bottle aside for now and recycle the bottom.

Find a bucket or plastic container that’s slightly larger than the bottle. This is the container you’ll fill with water. You can also use another plastic bottle that’s bigger than the first one. If you do, just cut off the neck of the bottle so the rim is the same width as the body.

Fill the larger plastic container with water. Cold or warm water is fine. You want to fill the container almost all the way up — leave 1–2 inches (2.5–5.1 cm) between the top of the water and the rim of the container.

Using Your Gravity Bong

Put the bottle in the container of water. The open bottom of the bottle should be at the bottom of the container, and the neck and mouthpiece of the bottle should be at the top above the water. If water is covering the mouthpiece, you’re pushing the bottle too far down in the container.

Sprinkle ground up cannabis over the holes in the aluminum foil. You can break up the cannabis using your fingers, or grind it up using a grinder. Don’t grind it up too much or the pieces could fall through the holes.
Hold the plastic bottle steady with one hand as you’re putting the cannabis on the foil so it doesn’t fall off.

Light the cannabis while slowly lifting up the plastic bottle. This will cause the bottle to fill up with smoke. Use one hand to hold the lighter and your other hand to lift up the bottle. Continue to hold the flame to the cannabis while you’re lifting up the bottle.

Keep lifting the bottle until the bottom is almost out of the water. Don’t lift the bottle all the way out of the water or all the smoke will escape. At this point, the entire bottle should be filled with smoke.

Take off the aluminum foil and put your mouth on the bottle. When you remove the foil, some smoke might escape. That’s OK — just don’t push down on the bottle or you’ll force all of the smoke out.

Push down on the bottle slowly while inhaling. As you push the bottle down into the container, the smoke inside will be forced out and into your lungs. Don’t push down too quickly or you could take in too much smoke. Keep inhaling and pushing down until all the smoke is out of the bottle.
If you feel like you can’t take in anymore smoke, take your mouth off the bottle.

Exhale the smoke from your lungs slowly. If there’s more smoke in the plastic bottle, you can take another hit or push down on the bottle to clear it. When you’re ready to use your gravity bong again, put the aluminum foil back on, sprinkle more cannabis over it, and repeat!
