Four Italians, all instructors at a survival school, were used to dealing with harsh conditions. Among the other survival skills they had, they even had a lot of practice at building igloos, just in case they were ever stranded in the mountains and needed to stay warm to stay alive. Despite all their varied experiences, however, they weren't quite prepared to embark on their most recent challenge: building an igloo out of chocolate.
The dark chocolate structure was built for the Eurochocolate Fair in Perugia, weighs nearly 8,000-lbs and stands about 54-ft high. A regular igloo takes about 3 hours to complete, but the chocolate one took 23 hours due to the challenges posed by the material, which could both melt and crumble during construction. One of the builders said that it was "much more difficult than building a normal snow igloo," although the working environment in an air-conditioned room was probably a little more plesant than a snowy mountaintop.
