A glass beaker bong is a type of water pipe that is often used for smoking tobacco or other herbs. The bong typically has a pear-shaped body with a wide base, which allows it to be stable when placed on a table or other surface. The neck of the bong is usually long and slender, with a small bowl at the end for holding the material to be smoked.

Water is added to the bong, and the smoker inhales through the mouthpiece, which draws air through the water and forces it up into the neck of the bong. This action cools and filters the smoke, making it cooler. Glass beaker bongs are simple to use and easy to clean, making them a popular choice among smokers of all experience levels.
