bongs come in many shapes and sizes, but beaker bongs and straight stem bongs are by far the bestselling shapes. A beaker is wider at the base than at the neck. This maximizes the surface area of the water for a splash more filtration, while also creating a stable place to stand. A straight stem tube (usually complemented by a flared base) is sleek and efficient with a straight tube design. Both beakers and straight tube bongs can include a wide variety of cool percolators.
