This creates a vacuum that sucks the smoke down out of the bowl and into the empty bottle. Light Your Herb (Photo by: Gina Coleman/Weedmaps) IMPORTANT: DO NOT LIFT THE BOTTLE ALL THE WAY OUT OF THE WATER OR YOU’LL LOSE ALL YOUR SMOKE! Lift the bottle up enough that it pulls all the smoke down into the bottle but does not fully emerge from the water.
With the bottle now full of smoke, remove the downstem and bowl and place your mouth over the bottle opening. Gently and slowly push the bottle back down into the water. This will force the smoke up out of the bottle and into your lungs. If you don’t want to clear the entire bottle at once, continue holding it in the water and put the downstem/bowl back on top to trap the smoke.

Here’s how to make and use a waterfall gravity bong. To make a waterfall gravity bong, you will need the following: Empty plastic bottle Scissors or box cutter Downstem and bowl, or alternatively, aluminum foil Water. Begin by cutting a small hole in the bottom of the plastic bottle. It should be large enough to allow water to flow out of easily, but small enough to cover with your finger. As with the bucket bong version, you have two options to create a bowl for your gravity bong. To use an actual downstem and bowl, you will need to drill a hole into the lid of your plastic bottle. Press the downstem into this hole then slide the bowl into the downstem. Again, the hole you drill into the lid should be almost the exact same diameter as your downstem to keep things airtight. You can make a bowl using a piece of aluminum foil. Fold a square piece of foil and place it over the top of the empty bottle. Gently press down with your fingertips to create a slight bowl shape and use a paperclip, toothpick, or some other tool to poke several small holes in the foil. Remove the downstem/bowl combination and put your finger over the hole in the bottom of the bottle. Hold your finger over the hole in the bottle to avoid spilling any water. Now, put your downstem/bowl combination back onto the top of the bottle and pack it with a pinch of ground-up marijuana. As it smoke, remove your finger from the hole in the bottom of the bottle and let the water rush out of the bottle. As the water pours out of the bottle, the smoke gets pulled down out of the bowl and into the bottle. Once the water in the bottle is replaced with smoke, quickly place your finger back over the hole on the bottom of the bottle to trap the smoke. When you’re ready to take a hit from your waterfall gravity bong, simply remove the downstem and bowl, place your mouth over the bottle opening, remove your finger from the hole in the bottom of the bottle and inhale. If you’d rather not clear the entire bottle at one time, put the downstem/bowl combination back on top of the bottle and cover the hole in the bottom of the bottle with your finger. You can also cover the hole in the bottom of the bottle with a piece of tape to not constantly hold your finger in place. When you’re ready for more smoke, remove the downstem and bowl, position your mouth over the opening, remove your finger or tape from the hole in the bottom of the bottle, and inhale. Repeat the entire process until all the smoke is gone.

Imagine yourself unscrewing a pre-filled soda bottle filled with marijuana smoke, and then inhaling the entire thing into your lungs. This is called a gravity bong, famous for providing smokers with the same rush of a huge bong rip, with far less effort and minimal bud. Not to mention, it's made using everyday objects found in the home. There was one point in time where people had to find creative ways to elevate their high to levels the average pipe or bong couldn’t achieve.
What makes gravity bongs so gnarly is the fact that you make it yourself using simple materials lying around your house. Finally, all of those plastic bottles taking up the space in your trash can be put to use.
