Hey everybody, Sam here.

Last week's episode on beaches inspired us to get outside

and enjoy some summer sun.

So we're taking a break from Tandans this week,

but I thought what better compliment

to our beach episode than our classic episode about waves?

So please enjoy this encore presentation

as you lounge in the summer sun or, you know,

drive to work or do dishes,

whatever you do while you listen to podcasts.

See you next week.

Oh, and welcome to SciShow Tandans.

It's the lightly competitive knowledge showcase.

I'm your host Hank Green coming to you

with a new quality of audio.

I'm not saying it's worse or better.

I'm just saying it's new because it sat down

to record this podcast and my computer

gave what Apple calls a prohibitory symbol.

So I got a prohibitory symbol,

which is not a great, not great.

It's just not great.
