A gravity bong is exactly what it sounds like: a bong that uses the power of gravity to gather smoke. Like a regular water bong, a gravity bong also uses water, but instead of cooling smoke in a chamber, a gravity bong uses water to develop vacuum pressure that contains your smoke in a central location.

A gravity bong features just two small parts—a small container placed inside a larger container. The smaller container is connected with a bowl on the top, much like the top opening of a one-litre soda bottle. The smaller container is fitted inside the larger container. The larger container is then filled with water, filling the smaller container up to the neck.

As you put your herb\cannabis into the bowl and light it, you gently pull upwards on the smaller container. As you inhale, you create a vacuum pressure. The pressurised space between the water and bottleneck fills with smoke. Once the required quantity of smoke is collected, you simply remove the top bowl and inhale while pushing down on the smaller container to force the smoke out and into your body. 

Benefits of a Gravity Bong

There are many major advantages to the gravity bong. One of the best benefits of using gravity bongs is efficacy. If you want to get high super fast, then the gravity bong is the best product. For newbies, one bowl pack is more than enough to get you pretty nicely baked. 

The second benefit of gravity bong is that it is economic. Unlike other consumption methods, gravity bongs don’t use up a whole lot of your bud. Although you typically burn an entire bowl pack in one hit, you will only have to repack it a couple of times. The bowl piece itself is usually small, so not a whole lot of pot is necessary.
