File this one under Simpsons jokes coming to life.

If you need a refresher: in the Season 8 episode of The Simpsons "The Secret War of Lisa Simpson," Bart takes a field trip to the Springfield Police Department where he subsequently finds a bunch of megaphones, lines them up end to end, and then shouts "TESTING!"

In the show, the shockwave created by this shattered all the glass in the town. Well YouTuber TheBackyardScientist became curious, as so many of us do, and came up with a perfectly cromulent experiment to see what would actually happen.

D'ohn't try this at home!
