The Lowest Cost Way to Make a DIY Bong at Home (Under $5!)

Let’s be honest: we’ve all been caught without a rig at the worst possible time. But you don’t need to spend $100 to get back in the game. In fact, the lowest cost way to make a DIY bong involves just a few household items and one or two essential Bong Parts that cost less than your morning coffee.

If you have $1.95 and a plastic bottle, you’re already halfway there.

The "Bare Essentials" Budget List

To get a smooth hit without the "makeshift" taste, here is your shopping list for the most affordable setup in Australia:

• The Bottle ($0): A classic empty Gatorade or juice bottle.

• The Grinder ($1.95): Our MWP 53mm Grinder is the key. You need a consistently fluffy texture so your DIY bowl doesn't clog. At $1.95, it’s the lowest cost high-quality plastic shredder you’ll ever find.

• The Cone ($5 - $10): Ditch the tinfoil (it’s harsh and unhealthy). Investing in a real Glass Cone or Brass Cone from our Bong Parts collection will last you forever and fits perfectly into any DIY stem.

How to Build Your Lowest Cost Rig

1. Prep your Herb: Load your grinder with weed and get that perfect shred. A DIY bong has less filtration, so the grind quality is everything for a smooth burn.

2. The Stem & Hole: Melt a small hole 1/3 of the way up your bottle. Insert a clean tube or hose.

3. The Seal: Use Blu-Tack or tape to make it 100% airtight.

4. Insert the Hardware: Pop your Glass Cone into the stem. Since you saved money on the bottle, this is where your quality comes from.

Why "Lowest Cost" Doesn't Mean "Low Quality"

Even with a homemade setup, the quality is definitely worth the price when you buy genuine MWP parts.
