A group of Estonians built a 2 kilometer underground tunnel in order to smuggle 6,200 liters of vodka out of Russia. They claim it was done to save money on taxes, but I think it's just a good-sense measure if you're prepping for the apocalypse. Which they clearly are, since this is the third tunnel found in this area. Is there an underground world secretly storing away all the booze and party favors to mark the end of a surface existence? Until the biosphere collapses and we're begging to use their secret underground pipe system, the smugglers will have to pay 57,000 euros in fines. [via Mysterytopia]
