I was reading an interesting story about an unexplained phenomena called the Naga fireballs. These strange fireballs occur once a year in Thailand along a 250 kilo section of the Mekong river in late October.
Naga fireballs are golf ball to Basketball sized glowing red balls that rise straight up from the river and then fade away. The phenomenon has become so popular that there is even a festival for it each year called the Bang Fai Phaya Nark festival. Find it hard to believe? Check it out.
