Hi, listeners. I'd love to tell you about one of our podcast friends, Who's Smarted? On every episode of Who Smarted? The trustee narrator takes kids on epic adventures of discovery to learn about science and history. Using time travel apps and other cool inventions, trustee can go backwards or forward in time,

shrink himself down to explore inside the human body, or visit outer space, other planets, or the ocean deep.

There's literally nowhere in the universe the trusty narrator can't take you to visit and learn about.

With episodes averaging 15 minutes, it's the perfect length for

car rides, meal times, break times, bath time, and bedtime. And anyone can learn fun facts from

Who Smarted, even adults. Search for Who Smarted wherever you get your podcasts.

Ten years later, Emil Berliner built on that invention to make the gramophone.

Unlike the earlier phonograph, which used
