The glass beaker bongs are the more basic style of glass water bong. Its distinguishing feature is the wide beaker base. The wide base design not only prevents the hookah from tipping over when it is placed or used, but also provides a large enough space for smoke diffusion and filtration, further enhancing the smoking experience. Straight pipe beaker bongs are the most common style, but of course the pipe can be designed to come in a variety of shapes and sizes. There are various extended styles and add-ons for these hookahs.
