Tong Setan, that's how we call it in Indonesia. Another folk entertainment full of thrill and amazing tricks showed by the bikers. The show lasts for 15 minutes, with the bikers moving in a constant speed inside a giant wooden bowl. People can give money directly to the bikers, they will ask for it and just grab the money from your hand. The motorbike itself produce very loud noises, no wonder many people covered their ears.
