Ping pong is a super fun game. It’s like miniature tennis, where people use paddles to make balls fly across a table., and sometimes way, way up in the air!

How does gasoline turn into exhaust?
00:06:13 | January 10th, 2025
Lots of cars, trucks and buses are powered by gasoline. You put the gasoline in a little hole on the side of the vehicle, it powers the engine and then it comes out of the tailpipe as exhaust fumes. But what’s going on inside that engine? And how does gas turn into exhaust anyway? We asked chemistry professor Dr. Josie Nardo to help us find the answer.

There are all different kinds of trees in the world, from towering redwoods to tiny willow trees smaller than an action figure. Why are there so many different sizes of trees, anyway? We asked tree expert Jake Miesbauer to help us find the answer.
How were black holes first discovered?

How do stethoscopes work?

Have you ever been to the doctor and had them listen to your body with a stethoscope? It’s that funny looking thing that looks like a long rubbery tube with a round metal circle on one end and two ear pieces on the other. Doctors always seem to have one handy, but what is it and how does it work? We asked pediatrician Emma Gerstenzang to help us find the answer.
How do sinkholes form?
00:06:04 | December 16th, 2024
Have you ever seen a sinkhole? These are spots in the Earth’s surface where the ground has collapsed and formed a hole. Sometimes they can be more than a hundred feet deep! But how do sinkholes form? We asked geologist Hazel Barton to help us find the answer.
What would happen if I went inside a black hole?
00:05:57 | December 13th, 2024
Black holes are super dense spots in space. They have so much gravity that when something falls into a black hole, it can’t escape. We asked UCLA astrophysicist Dakotah Tyler to help us imagine what it would be like if we traveled through one of these dark marvels.
