Employees at the Handwerkskollektiv carpentry business in Zurich were invited to a party hosted by the owner of a house that they had built. Christoph, Ben and the others wore their traditional heavy-timber carpenter clothing. To make the party more special, they demonstrated this beer opening trick, which proved to be a big viral hit when it was uploaded to YouTube and gained more than 400,000 views.
