Select between a bong for dry herbs and flowers, or for dabs and concentrates (called dab rigs). There are number of factors to consider, but it is mostly up to preference. Every bong or rig has different percolators or percs, which diffuse smoke differently. Most customers search by looking at style and function, and consider things such as: Price Size and Height Material - Glass or Silicone Style Percs

Glass bongs are usually made with quality borosilicate glass while silicone bongs are made with food grade BPA free silicone. Glass is more heat resistant, and many people prefer the feel of glass as a texture. However, glass bongs are more fragile than silicone bongs. Silicone bongs are flexible, and can be rolled up, and easily stored for travel.

Bongs work by allow the user to effectively and efficiently smoke dry herbs, tobacco, or cannabis in a better format. First, the bowl (often called a slide) is packed with your smoking material. Then, by inhaling through the mouthpiece, air is drawn. This heats the combustible material, and smoke is created. The bong diffuses the hot smoke through its down-stem or percolator, into the water - which cools down the smoke and delivers smoother, cooler hits for the user.
