Yes, you read correctly - we dedicate this category to the foot - namely the classic round base, which can be found on many bong models. No matter if you prefer a cylinder bong or a bulbous model. If your future treasure has a circular base, you will find it here.
Especially cylindrical bongs that are particularly tall and/or narrow benefit from the increased stability provided by a round footprint. They often have less room for weighted water or tend to become somewhat top-heavy. When combined with filters or pre-coolers, their instability may even increase. The round base ensures a better hold, especially with these cylinder bongs, due to its small and round standing surface - regardless of whether it is thick or thin-walled - and reduces the risk of the bong tipping over.
