Upright Bubblers, or Standing Bubblers are a classic shape of bubblers that features a vertical design. Upright bubblers consist of a bowl with a small downstem that leads into the main chamber - from there there is typically a mouthpiece attached that sits above the chamber, preventing any water form splashing. Upright bubblers are small, compact and easy to travel with, making all types of standing bubblers great for travel.
