Hello and welcome to SciShowTanjins. It's the Lightly Competitive Knowledge Showcase.

I'm your host Hank Green, and I'm joined this week as always by Science Expert, Siri

Riley.

Hello, ready to be an expert about science.

And a resident every man, Sam Schultz.

Hello.

I have a question for the two of you. If you had a country, what would be on the $1 coin?

Because there's not going to be a $1 bill that's a ridiculous idea and there will be no pennies

because we're all not monsters. But what's going to be on your $1 coin?

I think I would go very simple. I don't want to like memorialize anyone or anything. My problem

with coins is when they look too similar. I just want all of my coins to have a different

color and maybe different shape.

I like it.

Yeah, that's great.

The $1 coin will dress be a circle. It will get the standard shape because that feels

like a very practical thing. But then like half a dollar, you'll get a square or something

like that.

That way you'll be able to like look at a pile in your hand and be like, oh, I can count

more easily what I have.

Yeah, it's good. I don't know if it would work. I don't know if it would work easily in

the coin machines. But hey, this is ending. We're not doing that anymore. We're moving beyond.

I'm just going to touch it with my cell phone or better yet the microchip that's implanted
