The Rocket Festival in Thailand, called Bun Bang Fai, is an annual tradition organized by multiple villages just before the rainy season begins. The festivities stretch over many days and include music, dance performances and car stunts. But the main event occurs on the last day with the famous rocket launch competition.

The following clip shows one of the participant firing his homemade rocket, and it’s quite impressive. Definitely not what you’d expect a homemade rocket to look like!
