Frozen Methane Bubbles
|| +Amazing things in the world
These lakes may look like they are full of bizarre floating sea cratures, but they are actually filled with thousands of frozen bubbles.
Snapped across Banff National Park in Alberta, Canada, the natural wonders are made of highly flammable gas methane.
The gas - emitted by bacteria after they consume dead organic matter - is fairly harmless, but these bubbles can cause an explosion if lit.
