Ottery Tar Barrels
The  Ottery Tar Barrels Carnival occurs annually on the 5th November in the town of Ottery St Mary, England.
Over the course of the day 18 barrels are carried around the town from various public houses on the shoulders of members of the local community.  The barrels get larger throughout the day and are set on fire.
The biggest barrel is set alight in the town centre at the climax of the festival and is lifted with seemingly super human strength. 
This unusual tradition is thought to have originated from the practise of barrel rolling.
Aside from the barrel carrying, the carnival features a huge bonfire and a 'torchlight procession'.
