A gravity bong (a.k.a. a bucket bong) is a DIY smoking device. It can be quickly and easily rigged together, even by a bunch of stoners at 3am. Here’s how…
What Is A Gravity Bong?
A gravity bong consists of a 2-liter plastic bottle with the bottom cut off and a bucket of water. The bucket must be large enough to submerge the bottle up to the neck.
Apart from these items, you only need one more thing. A piece of aluminum foil with some pinholes punched through it and shaped into a bowl. The bowl should fit the mouth of the bottle. But it should also be loose enough to take on and off without difficulty.
And some weed and a lighter, of course!
Using a gravity bong couldn’t be simpler. But unless you know how, you could be in for a puzzling and potentially puddly time. So follow these instructions to stay warm, dry, and hopefully stoned.
Start off by submerging the bottle up to its neck. But make sure the mouth and the foil bowl stay clear and dry.
Next, crumble some weed and place it in the foil bowl. If you’d a modicum of class and style, you’d use an actual bong piece instead of a foil bowl. But who are we kidding? If you had either class or style, you wouldn’t be making a gravity bong in the first place!
Once you’ve crumbled your weed, light that shit up and let physics work its magic. Place a flame to the weed until it starts to smolder.
Once your weed is lit, keep the foil bowl on the mouth of the bottle. Lift the bottle by the neck until only the last couple of inches remain submerged.
If you get this part right, you should start to see magic happen! When you pull the bottle from the water you create a vacuum. And a load of air will rush through the neck and over the weed to fill that vacuum. You should now have a chamber full of dense, potent cannabis smoke!
Next, carefully remove the foil bowl with the weed inside it. Put it to one side. Now, cover the mouth of the bottle with your lips and push the whole thing back down into the water. Because you’re forcing water back into the bottle, the smoke will be squeezed back out – and directly into your lungs!
Why Make A Gravity Bong?
Why not? It’s fun and rewarding and gets you super high! It’s also a pretty neat way of keeping your smoke cool and fresh as it enters your lungs.
Besides, it’s so cheap and easy to throw together, it’s something every stoner should have on their “bucket” list!
