Combustion of Methane Bubbles
A three photo sequence: In the first photo, an inverted partial green bottle with bubbles, a black pipe, a clear tube, and a stand holding the bottle. In the second photo, bubbles in hand, a black ring stand, the green bottles sans bubbles, and a lit torch. The third photo shows the green bottle with less bubbles and clear tube, a stand, and a white flame over a lit torch.
Description: Methane bubbles are generated in an inverted 2L bottle connected to natural gas port. Once enough bubbles are produced, they are released and ignited.
