Steamrollers have a funny name for something that is essentially a straight pipe, cylindrical in shape, and made of glass, silicone, and other materials. Essentially, you place your dry herb in the bowl head like any other pipe, put your mouth on one end, and take a puff. But the carb hole on a Steamroller is the entire other end of the pipe, which you will need to cover with a hand or finger to take a puff. Follow through as you would with any other dry or water pipe. There are all sorts of different types of steamrollers and so we will explore the differences and any advantages or disadvantages with either of these.
