At an ice park in Russia, residents dug a crater into the ice from which it is nearly impossible to escape.
This video of the slippery hole, filmed on March 11, shows people trying to escape a so-called ice prison at the Oktem Park around 50 kilometers south of the city of Yakutsk, a port city in Yakutia, east Siberia.
Despite forming human bridges and attempting to push each other out, none of the five people in the crater could escape and kept sliding back into the center. In Yakutia, also known as the republic of Sakha, winter outdoor activities usually take place from late February to mid-April as it is reportedly too cold to go outside earlier in the winter.
From the months of November to February, temperatures can range from minus 30 degrees Celsius to minus 71 C. However, from the end of February it starts to warm up from minus 15 C to minus 45 C by night and minus 25 C to zero C during the afternoons.
The 'ice prisons' have been part of the park's attractions since 2010, and are made when a pit is dug out on a frozen reservoir or lake. Usually, few people are able to get out on their own, so when a person gets tired of sliding inside the pit, they ask a nearby spectator to help them get out.
