Hey, Bowser fams, Mindy-Year, and before we start the show.

Hey, Regg, what's that? A new pigeon drop-in?

Isn't that the postcard you send out to members of the World Organization of Wowsers every quarter?

I see it! What?

You need to see if I'm a member of the WLW first?

But Regg, come on, it's me, Mindy! Huh? You're not seeing a Mindy on the list? Okay, uh, try, Mindy. I think Thomas Fingerling signed me up. [crying] Yes! Can I get my pigeon dropping now? What? I got a wait for it in the mail?

It's right there! [crying] Okay, fine, guess I'll go way out by the mailbox. [crying] In the meantime, to get the next quarterly mailing from Regg,

grownups, you can sign your Wowser up to be a member of the World Organization of Wowsers by Monday, March 16th. [crying] It's so top secret I haven't even seen it yet. [crying] Now, where did I put my mailbox?

[crying] Bornups, when you sign your Wowser up to be a member of the World Organization of Wowsers, you also get birthday cards in the mail from me and Guy Ros, access to over 1,000 online activities inspired by our podcast,

[crying] [crying] [crying] [crying] Welcome to Hell's Way.

Your local neighborhood, all natural eco-conscious food pantry.

Remember, a sustainable future is just about full of way.

Okay, let me just check my shopping list here. Uh, Kienwak. Check. Kail. Check.

Tomatoes. Check. And... [crying] Bindi! What?

I thought we were supposed to be making a salad tonight. We are! Don't worry, guys, rise. These are green marshmallows. What kind of salad has marshmallows in it?

Uh, a good one. Please put them back. Oh, fine. But I'm keeping the maple syrup. Okay, let's see where I was.

Ah, yes, uh, tomatoes. Check. Okay, that looks like it's everything, uh, now to the checkout line. And this one doesn't seem too long.

Uh, yep, there's your seat. Thomas Fingerling? Oh, hey there, Mr. Rassie. What are you doing here? What do you mean?

I work here. You work at the Health Way grocery store. Well, sure. Why? Well, nobody else could seem to wrangle D-force.

Okay, I'm back from my bathroom, right? Uh, excuse me. D-force, you work here too? No. I'll just take the money.

That'll be $75. What?

You should probably just give her the money.

You don't want to see her get angry. Well, uh, I'm already angry. I'm going to ring. Huh. Okay, this car smells back, I rise.

But I really think we should get these budgy brownies for that. Thomas Fingerling? Huh. Give my cheap wars. Hi, no.

What are you two doing here? They work here. We work here. You do? Apparently.

I'll just take the money. Ah, she's just being modest. Chief forces, the fastest grocery bagger this side of the wherever we are. Whatever. Speaking of which, uh, you need a reusable bag for all these vegetables, guys, Rossie.

No, uh, sure. Oh, no, that's okay. I brought my own bags. There's somewhere in here. Where'd I put those bags?

Oh, here we go. Oh, those plastic bags? Uh-oh. Oh, what just happened? Maybe this is an all-natural, eco-conscious, full pantry.

Really? I thought it was a grocery store. They take their environmental issues here very seriously.

Plastic bags.

They are a big, no-no. But they're all a big plastic bags are different. How? Well, there she is. There's the lady that takes me and find them.

Get her. Come on. Hey, do you back in out of here? Come on, medieval. [screaming]

I brought my bag. I brought my bag. I need you for shopping. Oh, that was a close one.

Well, I guess that's what we get for forgetting our reusable bags.

Well, if everyone in there had actually given me a second to explain myself,

they would know that these plastic bags aren't actually all that bad for the environment. What do you mean? Well, I'll tell you about it on the way home. Come on, let's emulate and pontificate.

What? What can talk? Ah! You see, guys, these bags are bio-degradable. Bio-degradable, you mean they break down in nature?

Yeah, just like a banana peel or compost or an apple core. The bag breaks down just like that? Yeah, they're based on these plastic bags that were developed at the Japan Agency for Marine Earth Science and Technology. Well, that was helpful.

You mean jam stick? Yeah, that's much easier to say. Anywho, I was excited to try out these new bio-degradable bags that they developed.

It's sort of realized people would freak out so much.

Uh-huh, and how long does it take for these bags to fully disintegrate? Well, this research found that the bags lost 80% of their mass in just over a year. In other words, 80% of the bag disappeared in over a year. Ah, that's super fast, considering that normal plastic bags can take tens or hundreds or even a thousand years to fully break down.

I know! So, how does it all work? Well, Gyros, I could tell you. Yes. But I'd rather show you.

Look, we made it back to my gingerbread mansion. Oh, yeah! [sighs] I freshly baked the front door this morning. Come on, follow me.

Heee! Yeah! Yes! How sweet, hum!

Literally, because it's gingerbread.

Mindy, why is there a giant tank of water in the middle of your living room?

Oh, that's just for science, Gyros. For science, you needed a bus-sized tank of water in your living room for science? Yeah, you wanted to know how these biodegradable bags worked. So, we're going to run a little science experiment. Just like they did at Jamstack.

A science experiment about plastic bags in this aquarium? Yeah, part of developing these biodegradable plastic bags meant that the researchers had to observe how they broke down in sea water. Okay. And we're going to do the same.

Wait, this is sea water? Yeah, originally I brought this sea water home from our trip to the beach last week, and I was going to use it to cook potatoes for our salad tonight. So, let me just see if I understand the experiment here, Mindy. Okay.

We're going to take some of your plastic bags. Uh-huh. Put them in this giant tank of sea water. Yeah. And then observe them as they break down over time.

You know it. Let me just climb up this ladder here. Oh, okay. Now I just kind of fold the bags out of my pocket and drop them in the sea water, dropping in the bag.

But Mindy, didn't you say that it takes just over a year for these plastic bags to break down?

Uh-huh. So, we're just going to stand around here for a year? Yes, of course we're not just going to stand around for over a year guy, but that's what the wow machine is for. Wow, machine, where are we going?

Well, we're going in here. In the sea water tank? You know it. We're going to get up close in personal guy rods to see just how this plastic bag breaks down in the ocean. Come on, all me.

Wow, machines in the garage. Oh, okay. Walk, walk, walk, walk, walk, walk. Uh-huh. The name the door.

Sorry, I just been making a couple of tweaks to the wow machine. Hey, ride, ride team. The wow machine ready yet? Yeah, that's good enough for me. Come on, guy, rise.

Okay. Yeah, we'll be back in like 13 minutes. You can reinstall the temporal stabilizer when we get back. Hmm, it'll be fine. Stop worrying, red.

Come on, hop on in, guy, rise. All right. Closing the hatch. Strap in, guy, rise. It's time to shrink a five.

Shrink a five. Yeah, in order to see how this bag gets broken down, we have to shrink down to the microscopic level. If you say so, Mindy.

I do say so.

I'll strap in.

Uh, there's nothing to strap in with, Mindy.

Well, then you better hold on to something.

Because, here we go. All right, now let's see if we made it. All right. You want to open those blinds, guy, rise? Oh, uh, sure.

Opening the blinds. Whoa, oh, yeah. Where are we, Mindy? We can't you tell, guy, rise? We're in my giant living room.

See, water, aquarium. And that giant shelly fish looking wall in front of us? That's our plastic bag. Whoa, we really are small. Yep, we're on the microscopic scale now, buddy.

You could fit about five million wow machines

in the head of a needle at this size. And so, when does this plastic bag start to break down, Mindy? Yeah, in a couple of months. Let me just see if I could speed us up with a little bit of a good old fashion time travel. Now, where did I put the fast forward foot?

Down it. All right, here we go. Fast forward.

Okay, you should be coming up on three months, right?

Down, down, down. Phew, okay, let me just see here. What was that, Mindy? Wow! What's that sound?

That's the wild machines proximity alarm.

Uh, I have a bad feeling about this. Here it comes. What is that? Guy Roz, behold, the bag eating micro. Um, micro, you mean those microscopic teeny tiny little creatures

that live on and inside our bodies? Yeah, but they don't just live on our bodies, Guy Roz. They also live out in nature. They're like nature's invisible workers. Some live in the soil where they break down dead plants and animals

turning them into nutrients that help new things grow. And in the ocean, some microbes make oxygen for us to breathe. And these ocean microbes? Well, there are the reason these bags are able to be broken down. What do you mean?

Wait for it. Wait for it. Uh, wait for it. Mindy, is that micro-beating that plastic bag? Uh, huh?

And that is how the plastic bag is able to lose 80% or most of its mass in just a little over a year. Because they break down this biodegradable plastic in the same way that other microbes break down other tough materials? You know it. See, the scientists from JamsTech knew that there were other microbes out there

that eat oil and wood even some metals. So they had an idea. Yeah? If they can eat up those other things, then maybe they could add this newly developed biodegradable plastic to the menu too.

Huh? Oh, here comes another one. Oh, these microbes are hungry today. You know, Mindy, they actually look kind of cute. Yeah, it's of the most adorable little micro-organisms I've ever seen.

But Mindy, where's all that plastic go?

I mean, you know, after it gets eaten by these microbes?

Wow! Does that answer your question? Uh, did that micro-just? Two out that plastic bag? Yeah, it did.

Gross! It's not gross, Kaira's, it's science. These microbes are taking the plastic bag, digesting it, and then converting it into chemicals like carbon dioxide and water. Great job, buddies. Keep up that good work.

Whoa, Jikes! We better get out of here, Kaira's. Before this becomes a feeding frenzy. Could idea, Mindy? Strap in!

Uh, once again, Mindy, there are no stress. Oh yeah, well, Hannah, hold on to something. What does he do? Here, we... Kaira's!

Okay, don't...

Hey, Red, see?

I told you it would be fine.

Uh, sorry about the water. Hey, Red, where are you going? Boom! It's not bad at me. Symondia, what does this new technology mean

for the future of plastic bags? Well, single use are plastic that you use once and throw away. It's still a pretty big problem for our planet. Particularly in the ocean.

Yeah, have you heard of the great Pacific garbage patch?

Yeah, it's a huge area in the ocean. We're ocean currents trap plastic in other trash. Right, and it's super big, too. Like twice the size of Texas big. And super dangerous, because animals mistake the plastic for food

or get tangled in it, and the garbage never really goes away.

Yeah, but if more of that trash was made out of the same sort of plastic that these plastic bags are made out of, then a lot of them would break down and just over a year. And post less of a threat to the environment in sea life. So, how far away are we from replacing our everyday plastic

with this biodegradable stuff? Well, we've still got a long way to go.

I mean, there's a lot of plastic in the world right now,

but it is a good first step. You got to start somewhere. Reggie, you came back! [coughing] Alright, fine.

Hand me that mop.

That's the spirit, buddy.

But maybe we should bring a couple of my reusable tote bags this time. You know, just to be safe. Not a bad idea. Wow, in the world, we'll be right back. Croneups!
