Bongs are water filtered and have a large chamber to hold smoke. They have a stem with a removable bowl to clear the chamber. The water cools and filters the smoke and so you get massive hits.
They are made of different materials. Cheaper ones are made of plastic. Real bongs are usually made of glass. Glass is better. Roor bongs and other glass on glass pieces are the best.
Bongs can be anywhere from 8 inches to over 5 feet long. I think the optimal height is 2-3 feet for general use around the house. Great around the house, but they are too big and delicate to take with you everywhere.
Critically Rated at 17/17 for premium glass on glass bongs.
Critically Rated at 9/17 for cheap plastic bongs.
