Year 8 students were treated to some fun at the end of this term by learning about the science behind methane bubbles and subsequently getting their hands lit on fire, all in a safe secure environment of course.
The methane bubbles are created by passing methane gas into a solution of soapy water. The bubbles rise due to the fact that methane is much lighter than air. Methane is combustible, meaning, when heat is applied, it will react rapidly with oxygen forming carbon dioxide, water and generating a small amount of heat in the form of a flame.
