Water is nature's best filtration system. It does an amazing job of removing potentially harmful particles and leaving just the THC to be consumed. The smoke is first filtered through the water and then again through the coils in the glycerin chamber. The percolator in the bubbler drastically magnifies the filtration effects by creating more surface area for the smoke and water molecules to interact.
When the smoke hits the cooler water in the bubbler it's instantly chilled, and 99% of bubblers stop there. But for Freeze Pipe Bubbler, the fun is just getting started. Next on the smoke's journey is a trip through a frozen glycerin filled chamber for maximum smoothness and refreshment.
