The downstem is the piece of some bongs that acts as a cradle for the bowl to sit in. When you’re clearing your bong after a hit and pulling the bowl out, it’s coming from its cozy nook in the downstem. It usually comes in one of three sizes (10mm, 14.5mm, or 18.8mm), so check your bong when you’re shopping for a replacement.
