What's Inside an Etch A Sketch?

You probably know a lot about the Etch A Sketch, the classic drawing toy that debuted in the '60s, but do you know how it works? The father-and-son team behind the YouTube channel What’s Inside? decided to take one apart and find out.

After breaking through the outer plastic layer, Lincoln and his dad Dan discovered … a lot of aluminum powder. That silvery dust coats the screen of the Etch A Sketch and is responsible for providing a blank canvas for users. The knobs control a metal pointer that's fitted onto two crossed metal bars.

When you adjust those knobs to create a picture, the metal pointer moves, dragging along the screen and wiping away the metal powder. Those lines you see on an Etch A Sketch are actually just the blank spaces where the aluminum has been swept away. Shaking the toy covers the screen in a fresh coat of powder so the artist can start all over again. Learn more of the toy's inner workings in the video above.

After weeks of mailing out this year’s holiday cards, postage might be the last thing you want to think about. But the U.S. Postal Service has just given us a sneak peek at the many iconic people, places, and things that will be commemorated with their own stamps in 2018, and one in particular has us excited to send out a few birthday cards: Mister Rogers.

In celebration of the 50th anniversary of Mister Rogers’ Neighborhood, Fred Rogers’s groundbreaking PBS series that the USPS says “inspired and educated young viewers with warmth, sensitivity, and honesty,” the mail service shared a mockup of what the final stamp may look like. On it, Rogers—decked out in one of his trademark colorful cardigans (all of which were hand-knitted by his mom, by the way)—smiles for the camera alongside King Friday XIII, ruler of the Neighborhood of Make-Believe.

Though no official release date for Fred’s forever stamp has been given, Mister Rogers is just one of many legendary figures whose visages will grace a piece of postage in 2018. Singer/activist Lena Horne will be the 41st figure to appear as part of the USPS’s Black Heritage series, while former Beatle John Lennon will be the face of the newest Music Icons collection. Sally Ride, the first American woman in space, will also be honored.
