3 / 3   The faster the Boeoegg explodes, the hotter the summer will be based on local traditional weather rules. The burning of the famous snowman took a full 43 minutes and 34 seconds to explode in 2016, which is the longest time on record. In contrast, it took 20 minutes to explode this year, which predicts a poor summer. /VCG Photo
