That morning, freshman and sophomore students were preparing to take the ACT Aspire test when the bolt suddenly struck just before 8:30 a.m.

The principal said that the strike stole the students’ attention and many were excited to witness "such an amazing act of Mother Nature," Fox 11 reports.

The footage made its way to the National Weather Service (NWS) and the Green Bay outpost shared the video with a warning.

"You just never know when lightning will strike," the agency posted. "So the NWS slogan ‘When Thunder Roars Go Indoors’ please heed that advice next time you hear thunder."

The now-viral video has since been viewed over 10,000 times online.

"Whoa!! I'm sure the school kids will remember what they saw," one commenter wrote of the moment.
