If you’ve got flower but no piece, don’t panic — we’ve all been there.

Luckily, cannabis smokers are a resourceful bunch, and sometimes the best smoke sesh starts with a little DIY.

That's where a mason jar bong comes in. It’s a solid homemade option that hits smooth, looks (kind of) cool, and gets the job done when you’re in a pinch. Plus, it’s surprisingly easy to make.

Here's everything you need to know about making a quality mason jar bong at home.

What Is a Mason Jar Bong?

A mason jar bong is exactly what it sounds like — a makeshift bong built out of a mason jar. With the right setup, it can work just like a traditional bong, complete with water filtration for smoother hits.

It won’t replace your favorite glass piece, but it’s perfect for an emergency sesh or getting creative with friends and elevating your high.

What You’ll Need

You don’t need any special tools — just a few common items:

• 1 mason jar with a lid (standard size is perfect)

• 1 downstem or metal tube (a pen body or glass straw can work in a pinch)

• 1 bowl piece (or DIY one from a socket or foil — more on that below)

• A drill, knife, or screwdriver (to poke holes in the lid)

• Hot glue, silicone, or tape (to seal any gaps)

• Water

• Your favorite flower from the Mood Shop

Optional: A rubber grommet if you have one — makes things cleaner and more airtight.

Step-by-Step: How to Make a Mason Jar Bong

Here’s how to put it all together:

1. Prep your mason jar Start with a clean, empty jar. Fill it about 1/4 of the way with water — enough to cover the bottom of the downstem but not too much that it splashes up.

2. Make a hole in the lid Use a drill, screwdriver, or knife to carefully make a hole near the edge of the lid. This will be for your downstem. It should be just big enough to slide in snugly.

3. Add a second hole (optional but recommended) Make a smaller hole on the opposite side of the lid — this acts as your carb if your bowl doesn’t already have one.

4. Insert the downstem Slide your downstem through the main hole so that it sits at an angle and dips into the water inside the jar. You want it airtight where it passes through the lid — seal it up with hot glue, putty, silicone, or tape.

5. Attach your bowl If you’ve got a proper bowl piece, great. If not, you can improvise one using a small metal socket or a foil bowl shaped around the end of the downstem. Just be sure it’s secure and won't collapse mid-hit.

6. Screw the lid on Once your pieces are in place and sealed, screw the lid tightly onto the mason jar. You’re ready to test it out.

7. Pack and spark Grind your flower, pack your bowl, and light up. Use the second hole as a carb or cover it with your finger while inhaling.

Tips for a Better Hit

• Use a glass or metal downstem if possible — plastic can give off a weird taste (and may not be safe with heat).

• Angle the downstem so it hits below the waterline — this helps with smooth filtration.

• Try using ice water for cooler hits — just don’t overfill and cause splashback.

• If you're skipping the carb hole, make sure your bowl is removable so you can clear it.

What to Avoid

There are a few things you’ll want to steer clear of:

• Plastic bowls or downstems — These can melt or release chemicals when heated.

• Loose parts — Make sure everything is snug and sealed to avoid leaks or weak pulls.

• Overcomplicated builds — You don’t need to get fancy. Keep it simple and functional.

• Burning foil directly — If you go the foil route, make sure it’s shaped into a bowl that holds the flower, and avoid direct flame contact as much as possible.

Can You Reuse a Mason Jar Bong?

Absolutely — as long as you clean it between sessions.

Dump out the water after each use and give the jar a quick rinse to keep things fresh. You can also deep clean it with isopropyl alcohol and hot water just like you would a regular bong.

Just know that if you used hot glue or tape to seal the downstem, those parts might wear out over time. If that happens, just rebuild — the whole thing takes like 10 minutes tops.
