Bang Fai Phaya Nark
(Naga fireballs)
Bang Fai Phaya Nark (Naga fireballs)
is a phenomenon that the mysterious fireballs
rise from the Mekong river into the air above
water surface. The fireballs are smoke-less,
smell-less, and sound-less. They rise 20-30
meters straight up to the air then disappear
without falling back to the earth as the normal
fireballs do. Their sizes vary from a thumbsize to an egg-size.
The amount of the fireballs also vary, starting from
around 6.00 p.m. to 8.00 or 9.00 p.m. The
locations for spotting the fireball phenomenon in
the Mekong River are the area of Phon Phisai, Pak
Khad , Sung Kom, Sri Chiang Mai, and Bung Kan
districts in Nong Khai province. The fireballs can
also be found in other locations such as ponds and
streams near Mekong River.
The fireball event is an unexplained
phenomenon that generally takes place on the
full moon night of the 11th lunar month, which
also coincides with the end of the Buddhist Lent.
If there are two 8th months in a particular year,
the phenomenon will take place on the first
waning moon night of the 11th month, which
coincides with Lao's Buddhist Lent.
Bang Fai Phaya Nark in scientific views
In scientific concerns, Dr. Kanoksilpa, a
pediatrician at Nong Khai hospital, has
continuously studied this phenomenon for four
years, including scientifically conducted
experiment to investigate its occurrence. Here is
a brief information (Panida, 2538 B.E. : 78-79)
Bang Fai Phaya Nark may be an amount of
physical matter that can rise through water. It may
be a color-less and smell-less self-inflammable
gas that is lighter than the air.
The conditions at which the phenomenon
can occur are the areas of 4.55-13.40 meters
deep and underwater puddles that contain
gasses.
Those gasses are believed to be organic
materials such as dung, plant and animal
remains. These fermented substances create
adequate amount of gases to emerge from the
paddles and rise through water to the air above
water surface. The amount of gas in a fireball is
around 200 cc. When the 100 to 200 cc gas balls
rises 20 feet to water surface, its size expands up
to 310 cc.
When it rises 1-4 meters above water surface, its
size reduces to 100-200 cc, which is not larger
than an orange size, it then starts to be selfinflammable.
These properties exist in hot gasses of which
Methane and Nitrogen gases are their main
components.
