A bubbler pipe is a type of smoking pipe that combines the functionality of a water pipe, or bong, with the convenience and portability of a traditional hand pipe. Like a water pipe, a bubbler features a water chamber that cools and filters the smoke before it reaches the mouthpiece, providing a smoother smoking experience. However, unlike a water pipe, a bubbler is typically smaller and more compact, making it easier to transport and use on the go.

Bubblers come in a variety of sizes, shapes, and designs, with some featuring intricate glasswork and artistic details. They are typically made from glass or silicone and may have a fixed or removable bowl piece.

To use a bubbler pipe, the user fills the water chamber with enough water to cover the downstem, which is the tube that extends into the water. They then load the bowl piece with their smoking material and ignite it using a lighter or another heat source. As they inhale, the smoke is drawn through the water, which cools and filters it before it reaches the mouthpiece.

Bubbler pipes are a popular choice for smokers who want the benefits of a water pipe without the bulk and inconvenience of a larger piece. They are also favored by those who enjoy glass pipes' artistic and decorative qualities, as many bubblers feature intricate designs and patterns.
