How to Make a Gravity Bong

Gravity bongs are a classic and powerful way to enjoy cannabis. Whether you’re experimenting for fun or just curious about how they work, a DIY gravity bong is simple to make using everyday items, but if you want a smoother, safer, and longer-lasting setup, you can upgrade to a professional gravity bong in Canada built for performance.

This guide explains how to make a homemade water bottle gravity bong, what makes them work, and how today’s modern versions like the Stündenglass Gravity Pipe and Gravity B 13 Cosmo take the old-school concept to a whole new level.

A gravity bong uses water displacement and air pressure to create thick, concentrated smoke. As you lift the inner bottle, water pulls smoke into the chamber; when you lower it, the pressure pushes the smoke into your lungs for a massive, smooth hit. It’s one of the simplest yet most powerful ways to enjoy cannabis.

Homemade versions are made with bottles and foil, but modern glass and aluminum gravity bongs like the Stündenglass Gravity Bong or Gravity B 12 Cosmo offer cleaner hits, better airflow, and a design that’s made to last.

Before you start, make sure you’re in a legal area for cannabis use. This is meant for educational purposes and legal consumption only.

If you love the effect of a gravity bong but want something reusable and reliable, it’s time to upgrade to a professional setup. Here are Canada’s top picks:

The Stündenglass is the most advanced gravity bong in Canada. Featuring a 360° rotating glass and aluminum design, it delivers consistent vapor, smoother hits, and easy cleaning. Compatible with flower, concentrates, and hookah attachments — it’s a modern classic.
