Action News viewer Mike Cimino shared a video showing one of three dust devils moving through the Folcroft site where he was working.
Mike tells us the first two so-called 'dustnadoes' lasted about three minutes.
When those ended, a third started spinning. That one went on for roughly two minutes.
Mike says everyone was captivated by the dust devils, because it wasn't a windy day.
But the tiny whirlwinds apparently have more to do with heat than gusts.
