Yevgeny Panteleikin, a local blogger, dumps a bucket of cold liquid nitrogen on himself during a flash mob on the embankment of the Yenisei River in Krasnoyarsk, Siberia, November 20, 2014. Panteleikin and several other enthusiasts poured cold liquid nitrogen on themselves, bearing the temperature of about minus 196 degrees Celsius (minus 320.8 degrees Fahrenheit), while taking part in an event resembling the popular 'Ice Bucket Challenge' project and aimed at the popularization of natural sciences among children and teenagers. The experiment demonstrated the Leidenfrost effect phenomenon, in which a liquid produces a layer of insulating vapour that prevents the liquid getting into a direct contact with a surface much hotter than the liquid's boiling point, according to organizers.
