This is what sand looks like when it’s been hit by lightning, Called a fulgurite,
They are natural hollow glass tubes. Fulgurite is a naturally occurring process
in which glass tube formed by lightening strike in quartz, sand, silica , or soil
with a temperature of at least 1,900 °C it instantaneously melts silica particles
on a conductive surface and fuses grains together and this process occurs around
over a period of one second.
Their color generally formed white and black like sand colors.
Fulgurites can also be produced when a high voltage electrical network breaks and
the lines fall onto a conduct surface with sand beneath.
