The Lighthouse That Burned Its Own Lens | #Shorts #history

In 1886, the lens at Michigan’s Presque Isle Lighthouse got so hot from the sun’s magnified rays that it scorched the wooden floor inside the tower. The lighthouse keeper had to drape a blanket over it during the day to stop fires. It was bright enough to guide ships—and nearly burn down the lighthouse itself.
