Hey, Smarty Pants and Smarty Families, trusty narrator here with a must-listen podcast I Know Your Love.

It's a show called Steam Daydream, made by our friends at National Children's Museum in Washington, D.C.

In the new season of their show, they investigate everyday mysteries like why bubbles around and where trash goes

to uncover the science, technology, engineering, art and math that explains the world around us.

Every episode is 20 minutes or less and features real life experts and curious kids like you.

You can follow the fun by searching Steam Daydream with National Children's Museum wherever you listen to podcasts.

Psst, question. Where are you listening to this podcast right now?

Are you in a house sitting on a couch or a bed? Great.

But I bet some of you are listening in a car and some of those cars are speeding along a very particular type of road.

No, not the smaller roads or avenues outside your house.

The big roads with lots of lanes, few traffic lights and cars and trucks zipping by very fast in both directions.

Any idea what kind of road I'm talking about? Um, I'll give you a hint.

It rhymes with my way.

Did you say the highway?

Now, while you might know going on the highway is the fastest way to visit relatives,

go shopping at the mall or take a trip to another city or state.

What you might not know is how these criss-crossing highways transformed America.

So how are they built? Which are the fastest ones?

And can you land a plane on one?

It's time to buckle up for another whiff of science on.

Who smarted?

Who smarted?
