Hello and welcome back to the Curious Kid podcast.

We got curious about elevators way, way back, in episode 43.

That was back in July of 2019.

Olivia was only five years old when we recorded that episode, and now she's 11.

an invention that's kind of like the elevator's cousin.

get curious about escalators for the Pod Squad from Ontario,

Aiden, and Jonah. Getting curious about escalators is what we're up to this week.

Olivia, let's kick things off with the question of the week.
