The Great Stalacpipe Organ, found within Luray Caverns is the largest musical instrument in the world. Sound is evoked via stalactites being gently tapped across the three acres of the caverns.

We can thank Mr. LeIand W. Sprinkle of Springfield, Virginia, a mathematician and electronic scientist at the Pentagon, who in 1954, started a three-year project by scouring the cavern chambers and picking stalactites to precisely match a musical scale. Electronic mallets were wired throughout the caverns and connected to a colossal console.
When a key is hit, tone is produced via the rubber-tipped plunger striking the specific stalactite matching the note desired.

The Chicago River Reversal
Why it happened: In the late 19th century, Chicago's rapid growth led to severe pollution in the Chicago River, which flowed into Lake Michigan—the city's source of drinking water. This caused widespread illness and death.
How it was done: An ambitious engineering feat involved building a 28-mile canal that connected the Chicago River to the Des Plaines River, which is part of the Mississippi River system. By making the canal gradually deeper to the west, water was encouraged to flow from the river, away from the lake, and toward the Gulf of America.
The result: The reversal was a monumental success in terms of public health, transforming the Chicago River into one of the world's only man-made rivers that flows backward.

I’ve been there and listened to it. It was fabulous!

1939. Kansas Wheat. When they realized women were using their sacks to make clothes for their children, the mills started using flowered fabric for their sacks so the kids would have pretty clothes and made sure the label would wash out.
 
THAT is some great "re-purposing" of something that would otherwise be wasted after use.
 

The Left Side of Your Face Likely Looks Better in Photos​

Want to capture your “good” side in your next photo? Show off that left cheek. According to a 2012 study from Wake Forest University, the left side of a person’s face often expresses more emotion than the right, and onlookers tend to find that more aesthetically pleasing. When people were asked to rate the pleasantness of male and female profiles presenting both a left and right cheek, the participants overwhelmingly chose the left as more pleasant. One theory for this left-faced bias is that emotion and spatial awareness is largely dominated by the right hemisphere of our brain but is lateralized to the left side of our body, so emotions are expressed more intensely on the left side of our face. Interestingly, Western artists throughout the centuries have had a bias for painting portraits with subjects displaying their left cheek, especially women, with “Mona Lisa” being a prime example.
 

The First Color Photograph Was Taken During the U.S. Civil War​

Color photography is usually associated with the 20th century, but its origins date back to the early 1860s. On May 17, 1861, Scottish physicist James Clerk Maxwell, who later that very same year began publishing his world-changing electromagnetic equations, revealed the first color photograph to the Royal Institution of Great Britain. The photo showed the multiple hues of a tartan ribbon, and Maxwell created the image by having the same ribbon photographed three times using red, yellow, and blue filters and then combining them (known today as additive color theory). Maxwell first suggested this three-color method back in 1855, but it wasn’t until his collaboration with Thomas Sutton (inventor of the single-lens reflex camera), who actually snapped the images, that Maxwell’s vision finally came to life. Because the photographic plates were far less sensitive to red and green, the color wasn’t perfectly true to life, but it’s still considered the first color photo nonetheless.

The three original photograph plates used to make this photograph "now reside in a small museum at 14 India Street, Edinburgh, the house where Maxwell was born."
