00:01This machine from the 1800s could make pictures move long before modern movies even existed.
00:09It's called a zoetrope, a spinning drum with a series of drawings placed inside.
00:21When you look through the slits, each still image flashes one by one,
00:27tricking your brain into seeing motion.
00:30This works because of persistence of vision.
00:33Your eyes briefly hold each image, blending them into motion.
00:41In other words, this was one of the earliest steps towards cinema itself.
00:51Imagine seeing this for the first time in the 1800s.
00:56It must have felt like pure magic.
01:01And that's how a simple spinning drum helped change visual history.
