Naga Fireballs
Naga fireballs, also known as "ghost lights," are a phenomenon said to be seen annually on the Mekong River. Balls of glowing light supposedly rise from the water, floating several hundred feet in the air before disappearing entirely. The phenomenon is said to be caused by a giant serpent that lives in the Mekong known as phaya nak.
Written accounts from those who claim to have witnessed the Naga fireballs date back hundreds of years. Every October, the Nong Khai Province hosts the Phayanak Festival. On the final day of the celebration, attendees gather near the riverbank to watch the mysterious balls of fire rise from the waters and shoot up into the sky.
