Mother Nature sparked a sensation outside of a Wisconsin high school.

A large evergreen towering outside the building came tumbling down in an instant after being struck by a bolt of lightning, video shows.

The lightning strike outside of Wautoma High School, about 90 minutes west of Green Bay, Wisconsin, came just before 8:30 a.m. Thursday as the students were getting ready to take a test, according to Fox 11 News.

The bolt sent a flaming light through the entire center of the tree in the blink of an eye, causing it to immediately crumble into a heap.
