Frenchman Romain Vandendorpe set a world record for sitting immersed in ice cubes for the longest time, enduring the extreme challenge to raise money for childhood cancers. 

The 34-year-old health worker remained buried up to his neck in ice in a plexiglass cabin for 2 hours, 35 minutes and 43 seconds, breaking the previous record by 40 minutes. His training techniques included sitting in an ice-cold jacuzzi, training in a 500-liter freezer and then remaining buried in snow in the French ski resort of Chamonix.
