Hello, tumble listeners. Marshall here. Are you a teacher who works with kids in grades

three through five, or do you happen to know a teacher who works with kids in grades

three through five? If so, we need your help. We're working on a grant-supported project

that's studying the use of podcasts in elementary classrooms, and we need a group of teachers

to advise us during this school year. There's a small stipend as well. If you're interested,

there's a link to apply in our episode description. Thanks!

Hi, I'm Lindsay. And I'm Marshall. Welcome to tumble the show where we explore stories

of science discovery. Today we're talking about toilet. So you finally found an outlet

for all your potty humor desires. It wasn't hard to find. And it's all in the name of

potty science and engineering because we'll be plunging into the past present and future

of flushing to discover how toilets don't just save us from stinky smells. They save lives.

Today's question comes from our listener, Ellie. Hi, my name is Ellie. I'm nine years old.

I'm from the Philippines. My question is how do toilets work?

I just know you push a button and everything goes somewhere else, which is not here. And that's

all I really need to know. But where does it go, Marshall? What happened? I don't know just

out of the house. That's all I care about. Out of the house. Well, I think our listeners are a bit

more curious than you. So let us them. How do you think that toilets work? And how do you think

that they were invented? Because we'll be back with a toilet expert who will guide us to the answer

right after this.
