[00:00:05]Before TV and cinema, the Mutoscope was the [music] first personal film device in history. It appeared in nearly every entertainment venue in the late 1800s.

[00:00:12][music] Inside, thousands of photo cards were packed into a drum. By turning a crank, users created the illusion of motion, bringing the images to life through a small eyepiece. [music] Each coin-operated machine featured a different theme, from comedy to pin-up girls. With the rise of cinema, it slowly faded into nostalgia. This guy turned 3D printing into a premium business. He scans people in a small studio, then prints ultra-realistic mini figures that look exactly like them.

[00:00:36]Every piece is personal, emotional, and perfect for gifting. The process looks insanely satisfying on camera, goes viral fast, and brings non-stop orders.

[00:00:44]People holding lighters to snow and claiming the government replaced it with plastic because it turns black, barely melts, and also smell like chemicals.

[00:00:51]But what's the truth behind it? First, the black color isn't the snow burning, it's actually just soot from the lighter because tiny carbon particles from the flame stick to the cold surface. But what about the snow not melting? Because snow traps a lot of air that makes your tiny lighter melt it extremely slowly.

[00:01:07]You don't see it drip because snow is porous, like a sponge, which means the melting water gets absorbed back into the snowball. When you drop an apple and a feather from above, of course the apple will hit the ground first. But about 400 years ago, Galileo explained that in a vacuum with no air resistance, they would fall at the same speed. This idea was tested inside one of the largest vacuum chambers in the world.

[00:01:26]The space is surrounded by thick steel walls and is normally used to test satellites. They used powerful vacuum pumps to remove all the air and create the only near perfect vacuum on [music] Earth. When the chamber reached that state, everyone watched closely as they pressed the button to release the feather. Back in the 1600s, Aristotle claimed that heavier objects always fall faster, and people believed that for a long time. But Galileo was the only one who suggested that without air resistance, everything should fall with the same acceleration. And after 400 years, this has finally been proven in a way everyone [music] can see. Gravity pulls all objects down at the same rate of 9.8 m/s squared, no matter their mass.
