Janne Kapylehto Share Twitter Pinterest Email Planet Earth Outdoors Weather Conservation If you don't get out much to skate, ski, walk or ice fish, then the long, cold months of winter will be a rather boring experience holed up inside. But if winter sports aren't your thing, then maybe a jaunt on an ice carousel might cheer you up. Created on a frozen lake by cutting out the form of a circle through the surface of the ice with a chainsaw, this ingenious large-scale disc uses a solar-powered outboard boat motor to propel it into motion.

Complete with a warming hut, wood fire and some friends to share it with, the ice carousel acts like a rotating island right in the middle of the frozen lake.

When they happen, it's usually in Scandinavia or North America, but they have been documented as far south as England. It's believed that they form in the slow-moving currents in the rivers and lakes of cold climates. Some discs as large as 15 metres (49 feet) in diameter have been recorded.

(Let's hope no one gets sick, frozen regurgitation is definitely not fun). As for the intrepid inventor, Kapylehto says he now plans to make a huge 164-foot ice carousel in Helsinki.
