00:06:36 | May 14th, 2024

We may not think much about sewing machines, but there are so many things we wouldn’t have without them! Think about how many things are sewn together in our everyday lives. Your shirts, pants, hats, pillows, backpack, even parts of your car seats! There’s no doubt that sewing machines were a revolutionary invention. But when exactly were the first ones made? We asked Articles of Interest host Avery Trufelman to help us find the answer.

People have all different kinds of animals as pets: dogs, cats, hamsters, gerbils, pigs, you name it. The famous artist Salvador Dalí even had a pet lobster that he took for walks on a leash!

00:06:33 | May 10th, 2024

Drums are the backbone of rock’n’roll…and most other kinds of music, too! Where would we be without a big bass drum leading a parade, or a jazzy ba-dum-CH after a well-told joke? But how do drums actually make their sounds? We asked drum maker Liz Aponte to help us find the answer.

Do snakes barf?
00:05:08 | May 1st, 2024

Throwing up isn’t fun, but it happens to everyone. Sometimes we vomit if we’re sick with a virus or an infection – and other times, it happens because we’re feeling dizzy or carsick. But do other animals barf too? Like snakes? We asked wildlife biologist Laura Kojima to help us find the answer.

If you fold a sheet of paper just right, you can create a paper airplane that zooms through the air! But how do you make sure that your plane zooms across a room instead of nose-diving into the couch cushions? What makes a good paper airplane?
