FLASH-FROZEN BUBBLES
Lake Abraham in Alberta, Canada, is exposed to such sudden temperature drops that gas bubbles are frozen mid-movement to form this stacked-disc spectacle. Fixed in place before they can reach the surface and escape, these unique freeze-framed bubbles contain methane, a gas produced by bacteria as it decomposes plants and animals on the lake’s bed. The mesmerising pattern returns to motion during warmer months, as they thaw and fizz away into the atmosphere. This sudden release of methane can be a hazard due to the greenhouse gas’s extreme flammability.
