When SEALS Became SPIES?! π€― + The Post-it Note’s Shocking Origin!
Have YOU heard… about a DAY when SEALS became SPIES during World War II? Stay TUNED!”
Did you know that during the Cold War, the U.S. Navy trained ACTUAL SEALS – not Navy SEALs, but literal sea mammals – to perform covert underwater missions? In the 1960s, the U.S. Marine Mammal Program developed a top-secret program where California sea lions and bottlenose dolphins were trained to detect underwater mines, locate lost equipment, and even potentially intercept enemy divers!
These marine mammals could carry specialized equipment, use cameras, and were incredibly precise. One famous seal named Hoover could even mimic human speech! The program, which began in 1960, continues today and has been used in conflicts like the Iraq War.

On this day, we celebrate an epic story of scientific serendipity! In 1974, Spencer Silver, a chemist at 3M, was actually trying to create a super-strong adhesive for aerospace applications. Instead, he accidentally developed a weak adhesive that could stick to surfaces but was easily peeled off without leaving a residue.
For years, this “failed” invention sat unused until his colleague Art Fry had a brilliant idea. Frustrated with bookmark slips falling out of his church hymnal, he remembered Silver’s unique adhesive. The result? The Post-it Note – a product that would revolutionize office and home organization!
Today, over 100 million Post-it Notes are sold DAILY worldwide. Talk about turning a mistake into a million-dollar innovation!

On March 31st, 1889, the Eiffel Tower was officially opened to the public – but get this: most Parisian artists HATED it! A group of prominent French artists and intellectuals even signed a protest petition calling the tower a “useless and monstrous” structure that would be a “gigantic black smokestack” dominating the beautiful Paris skyline.
Today, it’s arguably the most recognizable landmark in the world and receives around 7 million visitors annually. Talk about a plot twist in architectural history!
