A bowl, also known as a slide,is an essential part of every bong. Bowls are empty chambers for dry herb ortobacco, which, once packed, attach to the joint of your glass piece. You lighta heat source, and the hot air pulled through the bowl ignites the herb andcreates smoke through your bong.
Bowls come in a variety ofdifferent sizes and can be either male or female. Standard water pipes areusually female, bong bowls generally have male ends - but not always. Therefore,you need to pair your bong stem with the right plug so that they are opposites,otherwise you may end up with a new bowl that is not compatible with your bong.
