Gravity Bong

A gravity bong is a type of smoking device commonly used for consuming cannabis. It typically consists of a container filled with water, a bowl or cap to hold the cannabis, and a mouthpiece. To use a gravity bong, the user submerges the container in water, lights the cannabis, and slowly lifts the container while inhaling. As the container is lifted, it creates a vacuum that pulls smoke into the chamber. Once the desired amount of smoke has accumulated, the user removes the bowl or cap and inhales the smoke from the mouthpiece. Gravity bongs are known for delivering powerful hits of smoke. There are more modern gravity bongs you can buy including Studenglass's gravity bong but the still involve using gravity as the method to push smoke to you.
