Thundering Question - 2

This fun photo of two brothers with their hair standing on end was taken on the top of Moro Rock in Sequoia National Park in 1975.

The elder brother recalls the day that they hiked to the top of the rock while the weather around them worsened. Suddenly the brothers realized their hair was standing on end, and scrambled to take a photo. Just minutes later the younger boy was struck by lightning, leaving both brothers with third-degree burns.

Lightning is an amazing effect caused by negative charge accumulating at the bottom of clouds, but can be fatal; up to 24 000 people are killed each year by lightning strikes worldwide.

Why did the boys' hair stand up on end just before the lightning strike?
