Australians Show the Dangers of Fracking by Setting a River on Fire

Fracking is a controversial method to extract gas and oil from rock. The process involves drilling deep into the earth and then using high pressure water, sand and chemicals to fracture the earth and release natural gas.  Apparently, one of the side effects of fracking is the ability to set water on fire.  More accurately, it seems to have released methane deposits from underground into the river.
