Definition - What does Silicon Bong mean?
A silicon bong is a type of pipe used for the consumption of marijuana or other smokable materials that is made out of medical grade silicon. Some of the benefits of using a silicon bong are that they are easy to clean, unbreakable, and flexible.
Silicon bongs are available in a wide variety of colors and sizes. They aren't as common as regular bongs, but they are considerably cheaper.
Hydrolife explains Silicon Bong
A silicon bong can be washed in a dishwasher. No solvents or alcohol are required, and there is no risk to the item breaking because it's too delicate. Likewise, silicon bongs can be carried around or packed in luggage without the risk of breakage. Accidentally dropping the bong will not result in breaking either.
If need be, silicon bongs can be bent to fit into other containers and are easier to put ice into for smokers that prefer it cold. Some models can even be rolled up for easier storage.
Not all bong smokers are convinced that silicon bongs are a great alternative to glass, but they do have many fans. One critique is the smell. Some smokers have reported a rubber-like smell to the pipe and that it affects the taste of cannabis. Others report that it quickly goes away after a few uses; still others report no such drawback.
The cost is usually touted as a plus for silicon bongs; they tend to be cheaper on average than most glass bongs.
