Hello and welcome back to the Curious Kid podcast.

For those of you that are longtime listeners, you probably know that my favorite episodes to research and record are what I like to call process episodes.

In these episodes, we learn about a process to find out how something works.

For example, we've done episodes on what happens after you flush the toilet or after the

garbage truck comes to collect your garbage. Well, we've got another super interesting process

to learn about today. So let's get curious.

Hello, Jacob and Olivia.

This is Scout at the age of nine and cash at the age of seven.

We live on Phillip Island, Victoria, Australia.

We would like you to get curious about vacuums, walkie-talkies, and plastic. We love listening to

you in the car going on adventures like going to the beach, going to see waterfalls, and going

to nearby towns and small car trips, like going to child, shopping, and going to the park.

We don't mind if you don't get to these because you have a lot of listener suggestions to get to.

My favorite episodes were probably the candy one and the teeth one, but I liked them all.

Cash's favorite episode was the Megalodon one.

We will always stay curious with you. Thanks.

Hi, Jacob and Olivia. My name is Florence. My son Ellis, who is seven years old, loves your podcast. We live in Vancouver in beautiful British Columbia, Canada.

Ellis and I listen to your podcast on our way to school and from school. His favorite episodes were curious about sleep and curious about scorpions.

Ellis is curious about guinea pigs, vacuums, and crows. Why are guinea pigs called guinea pigs?

What do their different sounds mean? How do vacuums work? When and where were they invented?
