Revellers enjoying a ride on a human-powered ferris wheel during the Thadingyut Festival, or Festival of Lights, in Yangon, Myanmar, on Monday. Gutsy ferris wheel workers spread out across the mammoth structure, as they manually turned the wheel with their strength, agility and body weight. The festival marks the day of the full moon in the lunar month of Thadingyut and comes at the end of a three-month period sometimes described as the Buddhist Lent. The festival is also a celebration of the Buddha's descent from heaven.
