FAQs

A gravity bong is a smoking device that harnesses gravity to pull smoke into a chamber, delivering powerful and highly concentrated hits. It usually consists of two main parts: a larger container filled with water and a smaller chamber that fits inside the container. The smaller chamber holds a bowl on top where you place your herb, allowing smoke to build up as the water creates suction.

A gravity bong operates by using air pressure and water displacement to deliver smoke directly into your lungs. To use it, you place your herb in the bowl attached to the top of the inner chamber, which is submerged inside a larger container filled with water. As you light the bowl, you slowly lift the inner chamber, creating a vacuum that draws air through the burning herb and fills the chamber with smoke. Once the chamber is packed with smoke, you remove the bowl to reveal the mouthpiece. Then, by gently pressing the chamber back down, gravity and water pressure push the smoke upward, allowing you to inhale a smooth, concentrated hit.

Unfortunately, no bong is immune to the sticky resin buildup that naturally accumulates with regular use. Over time, this residue can affect the flavor, smoothness, and overall performance of your gravity bong, making cleaning an essential part of maintaining your device. Fortunately, the Weeday modular system is designed with ease of maintenance in mind. Its fully disassemblable parts allow you to access every nook and cranny, making it simple to remove resin buildup before it becomes stubborn. Regular cleaning not only preserves the purity of your hits but also extends the lifespan of your bong, ensuring a consistently fresh and enjoyable smoking experience every time.

Check out our video on how to assemble a gravity bong, so you can start enjoying it today!

For tips on cleaning your bong, check out our comprehensive bong cleaning guide.

Fill your base with enough water so that the inner bottle is mostly submerged when pushed all the way down, but leave about 1–2 inches of space at the top. This ensures you have plenty of room to pull the bottle upward and create that perfect vacuum for a thick, smooth draw. For details, check out our guide on how much water to put in a bong.

They provide strong, concentrated hits and can be a cost-effective alternative to other smoking devices.

Common materials for DIY gravity bongs include plastic bottles, glass jars, or specialized glass pieces designed for durability and heat resistance. High-quality gravity bongs, like Weday’s, tend to be made from borosilicate glass that can withstand daily use for years to come.

Customer photo review of Bong Pro Tube - Cooling Glycerin

Quite literally my fave tube of all time. Saves the flavor, is kinder on my lungs, and preserves my beloved nugget ice for beverages while keeping my hits hella cool & comfy. Ordered the ice catcher tube just before this dropped—but was still quite happy to share that also-amazing option with a friend & fellow Weday lover, so I could pick this new option up for myself. Everyone wins when their hits are cold-filtered, really 🍃❄️

Nice product! I dropped it with its cover on and it didn’t break! Then while cleaning it I dropped it in the sink and I wasn’t so lucky. 🙁 So I’m going to buy another. They really are easy to clean.

Customer photo review of Bong Ice Catcher Tube Iridescent

💜 I custom built my bong, so this is just one of my set ups. I love everything about this! Functional, easy to keep clean, looks groovy. This bong is my favorite with the iridescent glass and ice catcher to match. The purple cover (my fav color) really brings out the beauty of the glass and the shininess turns metallic and acts as camouflage when it's dirty, giving it a whole new look. I'm hoping to order a bubbler soon! 💜

Love my heart percolator! I have two bubblers, the green bong cover and a Christmas tree percolator, a one hitter with filters, plus my multiple bowls and downstems.

Customer photo review of The Bubbler - Pumpkin 🎃

'Gourdo' is the best! Comfortably light-weight enough that you can one-handed but hefty enough that it's a nice firm grip! So sturdy, easy to unscrew, easy to clean! The bowl is small but I pack it good and I'm content! I love a glass piece that's also a conversation piece! 10/10 very happy with my purchase, shipping time and communication 🎃🍃🔥

Customer photo review of Sporeo – Mushroom Mini Bong

I love how cute this piece is. It fits well in my hand and comfortable when taking a hit. Only negative things are the bowl is really really small and since the mushroom is so large, you can't see how much smoke you're pulling when taking a hit. But it's still my new daily piece.

Customer photo review of 6mm Activated Carbon Filter (50 Pack)

Came for the dishwasher-friendly, easy-to-handle gear—but I’ve stayed for these filters & how much smoother they’re making my pipe sessions & one-hitter moments! I use flower for medicine & don’t tolerate edibles well. Here’s to anything that makes the impact even slightly less damaging.

Customer photo review of Bubbler Base Iridescent

Love this piece so much! The only caveat is that the bowl is a demure tiny thing. Would love to see some larger bowl options. That sai,d cleaning it is a breeze and it so easy to store!

Customer video review of Sporeo – Mushroom Mini Bong

I love this thing. I hand washed it before I used it bc i didn’t want to wait for the dishwasher to be done before I could use it. Going to run it in the dishwasher this weekend. Will report back if I have any issues but I don’t expect to. The only qualm I have is the inserts for the bowl and stem are much smaller than normal ones so I will have to buy replacements from Weday if something breaks but that’s not a huge deal if I’m being honest (but that’s pretty good if it’s the only issue I can think of)

I absolutely love this piece, definitely my favorite, bought a different neon green bowl for it.. Perfect for Thanksgiving halloween or everyday... also the bowl is real small like 1 or 2 hits, was expecting larger but found it so cute it didn't matter..

Customer photo review of The Bubbler - Matcha Latte

I FOUND THIS ON INSTAGRAM BUT IT ISN'T A SCAM!!!!!! This is genuinely THE BEST piece I have ever had. It IS 100% as easy to clean as they say. It takes me like maybe 3 minutes to clean. I'm soooooo bad about cleaning because it's usually a hecking ordeal, but not only are the pieces easy to disassemble, they fit together SO NICELY (and look cute) in action. 15/10 would recommend

IN LOVE 😍 This is by far the easiest best tasting one hit by far. I have ever used literally. It also has the ability to keep rolling when sharing with a friend 💯 the fact it can be taken apart to be cleaned is so exciting to me! 😂 the joy doesn’t stop there, when I found out you can put a carbon filter inside of it. I was sold. Thank you Weday!

Customer photo review of Rukus - T. rex Bong

I love my little Dino buddy, but I wish these had the same threaded joins as the other bases and tubes. The rubber is not insulated from the water, and I'm two days into trying to deodorize this one from wash day. He hits delightfully, I'm just not sure the smell is coming out.

I bought this for myself / my older sister who smokes, and oh my goodness it works soooo well!! In my opinion if you put a little bit of product in the bowl and then tap the bottom of the bowl on a table or your hand it packs it perfectly, just light carefully and enjoy!! I will be getting a wic/ longer longer as my standard bic keeps burning my hands.
