Quarnevalen is one of the largest public events in all of Europe. Every three years, about 1,600 students spend one week working on fun and often technologically advanced floats (in Swedish: ekipage) that will be part of a big parade around Central Stockholm on Quarnevalsdagen. According to estimates by the Stockholm police, about 400 000 see this parade, and if you’re a student in Stockholm it’s something you just can’t miss. The years between Quarnevalen, Squvalp is arranged instead. Squvalp is a one-day carnival where about 500 students build their own rafts. Yes, the Squvalp carnival is floating on water!
