Downed power lines from storms create freaky-cool phenomenon

Yesterday's storms were no joke. Even for those of us fortunate enough to dodge tornadoes, high winds still led to downed power lines across the city.

Those fallen lines created a phenomenon that's at once neat and which demonstrates the terrifying power of electricity.

According to a tweet from the Indianapolis Fire Department, heat from fallen power lines turned the very ground into glass.

Traditionally, glass is made by heating sand. The silicon dioxide present in sand (or in this case, dirt) melts to form the hard substance. And those temperatures need to be hot -- up to 3,200 degrees. IFD says it's the combination of high and prolonged temperatures that caused the weird, lumpy formations.
