The Prometheus Bubbler in Purple is an ultra durable and convenient bubbler made by Pyptek. All of Pyptek's Prometheus products share the same signature exoskeleton made of anodized, aircraft grade aluminum, making their pieces virtually unbreakable and longlasting. There are two "viewing windows" where you can see the bubbles moving as the piece is being hit. The showerhead percolator creates great filtration and helps to cool your smoke as well, giving you big, cool and clean hits every time. The bubbler can sit straight up on it's base and also at an angle and comes fully assembled, but is easy to disassemble when it comes time for cleaning.
