We've always done our experiments in very small places. But now people want to see huge experiments, things we've never done before. I don't know how to do it.
-It will be worse there. -We can't take any chances. One, two, three.
. . DAY 01 Hey, guys!
Sorry I'm late. As you know, from time to time I like to create opinion polls, to know what people think about Manual do Mundo, what they want to see or change. It turns out the audience wants to see big experiments, and I don't know how to do that.
How big, though? They want to see things we haven't done in 11 years of Manual do Mundo. Some people are doing these huge elephant toothpaste experiments.
They get bigger every time. What if we do an elephant toothpaste. .
. We need to remember last time we made elephant toothpaste, though. It didn't work out very well.
We struggled with the mixture. It didn't work 'cause it wasn't properly tested. We didn't figure out the recipe.
We can keep testing until we find the perfect recipe. Let's look at who made the biggest of all time, and let's make it bigger. -Break the world record?
-Yes. We have to break the world record, for sure. If we put out an invitation on YouTube, calling people.
. . -Like the fans?
-We can't fail them. That's what I was gonna to say. It would look pretty bad.
We can do it, as long as we can test it first. Can you handle the technical issues? -Yes.
Yes, we can. -Sure? Let's run the tests.
Meanwhile, we'll deal with the red tape, and you handle the schedule. One more thing. A series like this needs a name that is up to the task.
"Chutar o balde" is a Brazilian idiom. We use it when people lose their fear and decide to go big or go home. It's like to go all out, to be bold, to do something for real.
It literally means to kick a bucket, crumple it, smash it, shatter it. . .
Easy, before we kick all those buckets, we still have to find the recipe. Take it easy, Iberê. Take it easy!
Three dyes for the first test. DAY 02 Regular dye, powdered dye, -and wall paint dye. -Okay.
But safety first. The only dangerous thing in this recipe is the hydrogen peroxide. If it gets on the skin, it may hurt.
Once the foam is formed, it loses oxygen and it isn't dangerous anymore. But while we're preparing the ingredients, it's good to be safe. Elephant toothpaste is a foam generated by the oxygen released by the hydrogen peroxide.
HYDROGEN PEROXIDE It's called this because some people put dye on the border of the beaker when they do the experiment. It turns into a colored foam that looks like toothpaste. The foam happens because the hydrogen peroxide releases oxygen.
If we could look closer, we would see that a hydrogen peroxide molecule is very similar to a water molecule, except that it has one more oxygen atom. When we add potassium iodide to hydrogen peroxide. .
. POTASSIUM IODIDE . .
. it releases an atom of oxygen. It becomes regular water and oxygen atoms merge in pairs.
OXYGEN It turns into the oxygen gas molecule, known as O2, the one we breathe. If we add some soap to it, the oxygen gets trapped inside the bubbles and that's why it creates so much foam. We have four tests to do.
Which dye makes the prettiest color? Which soap makes the most foam and so is cheaper? Is it better to use pure hydrogen peroxide or dilute it with water?
Potassium iodide is diluted with regular water before it gets mixed with hydrogen peroxide. Should we try to use different amounts of water? For each one of these tests, we will have to make several elephant toothpaste recipes and compare the results.
OXIDIZER 5. 1 CORROSIVE 8 The first test is a dye battle. Let's see which is best.
. . .
97, 98, 99, 100. -One, two, three and go! -Two, three and go!
FOOD COLORING - POWDER DYE - DYE FOR WALLS Wall paint dye is way better and brighter. We already know which dye to use. Now let's test the soap.
-Go! -Go! DISH SOAP - ULTRA DISH SOAP DETERGENT - LAURYL -The lauryl?
-It's a tie. Only the detergent reacted faster. -Let's go with the cheaper one, then.
-You're so stingy. That's just a nasty rumor. I would use the regular dish soap, then.
It's simple, cheaper and it works. We need to test the hydrogen peroxide dilution, because we may be using a stronger hydrogen peroxide. Outside of Brazil people use 100 volume, that's half.
-Mix the soap. Go! -Go!
Look! Growth delay. HYDROGEN PEROXIDE DILUTION Definitely the 200 volume.
Rumor has it that we only have an hour to do the tests. Are we? Yeast works as a catalyzer to release the oxygen from the hydrogen peroxide.
Hypothetically it should work like the iodide, and it's way cheaper. So, if yeast works, Mari will jump up and down. Go!
We need to find out if we were supposed to use more or less yeast than we did. To figure it out, we have to check if there's any hydrogen peroxide. I think the best way to do that is to use iodide.
No, I don't agree. There is still a lot of peroxide in the first beaker. Guys, wait a second.
I'm talking to Katia. We can't use yeast. Not for a world record, anyway.
If it won't work for the record, then let's just move on to the next test. Our experiments keep going wrong. Every day.
It's so frustrating. There are many things that we've wanted to publish, but that we still haven't figured out, so we haven't posted them yet. I'm diluting the potassium iodide.
Let's check it out. The first got just over three. The first.
We got it. The first wins, 25%. POTASSIUM IODIDE DILUTION Mari broke the beaker.
She thinks it's okay because there weren't any tests left, but no. If I let him, Iberê would spend 24 hours just testing. Now we have a couple of things to decide.
How much potassium iodide and how much soap we should use. IODIDE VS SOAP Only thing is we have to test both things at the same time. What happens if we use more iodide and less soap?
Or if we use less iodide, but a lot of soap? To cover all our bases, we have to do cross testing. That means that for every amount of potassium iodide, I have to try every possible amount of soap.
All together, that means 16 elephant toothpaste recipes. First cross test, iodide versus soap using half the amount of soap. Second cross test.
3rd CROSS TEST IODIDE x SOAP Jesus, that is wizardry. -Last one. Go!
-Go! -Look at that. -We have the recipe, Mari.
We figured out the perfect formula. For every liter of hydrogen peroxide, we have to mix 30 milliliters of dye and 70 milliliters of detergent. Another flask gets 250 milliliters of water and 20 grams of potassium iodide.
Of course that recipe will be multiplied by a hundred. We've determined the recipe for a small experiment. But to test a big one, like for a whale toothpaste, it would be huge.
We've already made a mess here with these tests. I agree. I have to find a bigger place for a bigger test.
There are a lot of experiments we can't do at Manual do Mundo because there's no room. It's tight. DAY 03 But Mari has this huge shed.
This is my opportunity to test out all kinds of experiments. There it goes! How do we turn it off?
Go! We'll just have to eyeball it. Done!
It was really hard to dress that shed, to put in all that structure. Then when we got there, those experiments wouldn't be useful. That's when I realized that it was unnecessary to the project.
It was kind of a waste. Iberê wanted to have fun. Mari, tell me something.
Is it easy, what we do? -No. -No, it's not easy.
So, if we don't have any fun, it would be really boring. That's the nature of Manual do Mundo. Manual do Mundo is not a school, it's not a manual for doing things.
Manual do Mundo is learning by having fun. So, if we don't take time to laugh, and try things we've never done before, and have fun together, there's no point. I think that it was really fun for everyone.
I think that people will have a lot of fun watching it, too, for sure. We're on a tight schedule, though. I'm worried that we won't be able to do it.
That's why I'm so concerned. Okay. We'll have fun once we create the giant foam, then.
-Okay. -All right. Deal.
For elephant toothpaste, we have to think of a structure. . .
DAY 04 . . .
that'll pour the iodide into the peroxide at once. It needs to be precisely synced. It can't drop either too early or too late.
It has to be safe, too. If there's a wind or someone decides to run into the foam, people can get hurt. This is our first big experiment, with so many people involved.
And in such a huge space. We'll only get to know the people on the day. And the worst part of it is we can't test it.
We'll only find if the structure works once we get there. Here, babe. We have a soccer field.
Did you get a little pool to put under the structure? I got a tarp to put there. -Okay.
-The tarp goes below it, right? We also got some security tape so that no one crosses it. Even with the tarp and the little pool, people might feel like touching the foam.
So you'll create a barrier around it. Yes. Also with the security tape, people will stand clear of the experiment.
-Did you do the tests? -I did. This is our water tank.
It goes in the center of your pool. Around that we'll put this mechanism. It's a round table with a hole.
Above it go the buckets. There's a rope attached to the bucket. It goes below the structure.
Someone will have to pull it. As soon as they pull it, the bucket'll flip and pour. Just like it's something here.
Like someone's is kicking the bucket on the corner here. And what's inside? The hydrogen peroxide mixture.
What about the bucket? It contains the potassium iodide. And that part is really critical.
We can't let a single drop of potassium iodide fall into the water with peroxide, or it'll ruin everything. It'll react and release all the oxygen, and it'll all go wrong. So, as soon as we finish this, we have to be really careful.
-Let's test it now. -I have the ingredients. I'll pour it in directly.
All right, let's see. It's like magic, isn't it? Oh, no, it reached the people!
It'll be even worse out there. Because it got up in here. It'll expand 'cause it's heavy.
We can't take the risk. -No, let's. .
. -No way. We have to change the plan.
It's too close. It's tomorrow. Let's go home, rethink the safe zone and.
. . -Okay.
-Let's see what we get tomorrow. We always do the Manual do Mundo experiments in small places. DAY 05 We'll only know if planned dimensions will work by measuring.
Just by looking at it, I can't even imagine! Wow, Mari! It's huge!
We've never done something this size. I don't even know how to measure this. We work looking to a camera.
We don't know who's on the other side, what those who watch Manual do Mundo look like. Once we invite them on the internet, and they come to us, we'll able to see through that screen that separates us from the audience. My biggest fear was that people wouldn't show up on the day of the experiment.
Because the first invitation we sent out had a lot of wrong information on it. I came from Poços de Caldas, Minas Gerais. Holy cow!
There are so many people that follow Manual do Mundo, and they attend to the events, no matter where. Sometimes people travel hundreds of miles by car. Silmara, for example, took a day off work to help us in our attempt to break the record.
She made us this piece. This is handmade. We have it hanging here in our garage at Manual do Mundo.
Let me give you a hug. What's up? Thank you.
I have to say that I’m very happy. When I saw the invitation, I said, "I’m going, no matter what. " Thank you for the opportunity.
-Thank you for coming! -Thank you, guys. Let’s go!
Help us bring it down, please. If the wind keeps blowing like this when we're mixing the ingredients, it won't happen. We can't do the experiment with this wind.
Is this good? I'm putting the wooden structure, so that it holds the tarp. Share it, please.
It's so big that we don't know where to put the tarp. We wanted to put it in the middle of the field. I think we got it right.
It's very important for this experiment that these buckets flip in sync. One, two, three. .
. Go! I guess we're going before "go," that wasn't supposed to happen.
I guess we need to practice a lot because. . .
-Let’s practice. -We can’t practice too much. -Let’s practice one time.
-I'm nervous already. One, two, three. .
. Go! Mari, we aren't in sync yet.
It's already late. Let's do it because I'm afraid it won't work out. We're running out of time.
The field is huge. Everyone is helping to get things to the middle of the field. Also prepping the experiment will take a lot of time.
I'm feeling unsure. You are our adjudicator. What do we have to do, Camila?
You are exposed to outdoor weather, right? So, since we're talking about a chemical experiment, it's very unpredictable. The measurement has to be done with just one volume, it can't dissolve.
So, if the wind picks up. . .
If pieces get torn off, do they count? No, they don't. There are a lot of rules because this is serious.
We are talking about making dreams come true. We have our dream of breaking the record. Will you help us to make it come true?
It's up to you. I'm here just to watch. Too light, right?
-Is that good? -I think so. Keeping the foam together is just one of the rules.
We also have to clean the water tank in front of Camila, to show that we didn't put any hidden ingredients in there. And wait for Anderson, the engineer, to check if our measurements are correct, to make sure that we're not cheating. When it's actually time to measure the foam, we will have to hurry up.
So we have only a few seconds to measure everything, before the foam starts dissolving. Would you mind taking notes? He can't take the measurements.
KEEP YOUR DISTANCE What's up, guys! Are you ready? Ready!
Fernando, come over here! Everything was all right until I heard Iberê calling for Fernando. I thought, "Here we go.
" People knew we were making elephant toothpaste 'cause we sent out an invitation, so some of them started messaging us telling us that an American channel was also trying to make one way bigger than ours. We had enough ingredients for three experiments, and the only way that we could make the biggest one would be to mix them all in one. To use everything that we had at once.
But Fernando, who had done the math, planned everything, had done it for a smaller size. We didn't know what was going to happen. Being safe, we had to do it.
So, let's make it as big as we possibly can. We didn't have a choice. We had to go big or go home.
It has reached 1080 liters! We needed a different water tank. I'm going to turn it over.
You're ripping the tarp. I'm feeling totally useless. The first reason is the fans.
They're waiting for us to start the experiment, but I don't know if it'll happen. The first thing that comes to mind is, "Can we do it tomorrow? " If we need to reschedule, what are we going to do?
-It's stopping. -We can dry it now, can't we? I think we have to hurry and make it happen now.
It's going to happen, it's going to happen! Take off those sticks, then you need to get rid of those puddles. The puddles, okay.
Yes, we need volunteers, I need adult volunteers. You, both of you, and you come here. It just stopped raining, we want to do the experiment, but Camila, the adjudicator, doesn't want to let it go on.
There's a bunch of rules that we have to follow and it's really hard to overcome this situation. -It's raining. -Water's gonna fill it again.
We have to stop. Let's get inside, guys. Is the plan to wait for the rain to stop for long enough to.
. . No.
It won't stop raining for long enough. It won't stop raining. I think we can mix the dye with the hydrogen peroxide.
Yes. The critical moment is when we pour the hydrogen peroxide in the water tank. -Yes.
-And we have to cover it fast. We have four PPE. We need four people to carry the hydrogen peroxide.
We can split the crew into three teams. One for cleaning, I'm in charge of that one. The second one is for the experiment, those who will bring stuff for the experiment and put it there.
And the third one, as soon as the peroxide is in, someone has to come with the tape to cover the hydrogen peroxide. Some people freeze up in times of chaos. I think that if we give up, we will frustrate everyone for no reason.
. . .
to go there and clean the pool. When we finish cleaning, we have to put this back. Now we have to get it dry, measure it again, bring it back.
It's a lot of work. There it goes, it has to be quick, before the rain starts again! When we pour the hydrogen peroxide into the tank, there's no turning back.
Because we can't get the hydrogen peroxide back. So that's an irreversible decision from the moment we add the hydrogen peroxide. Lower it to.
. . Watch your heads.
Now we have to get the PPE on and pray that it doesn't rain. Thank you! How's that?
I can't believe it started raining again. Guys, as you can see, we tried everything, got the materials out, you helped us. But we won't be able to do our big experiment today because we can't measure it while it's raining.
We don't think the weather will get better, and it'll be dark soon. -You need to get out of the rain. -You are already in a bad position.
I'm sorry! We did the math for this thousands of times, we all worked really hard today to put it all together. Everyone is here, in the rain, getting wet, thirsty, hungry, cold.
. . And there's a safety issue as well.
You can't just do it. We have to do it properly. A lot of people came to see the experiment, so we have to make elephant toothpaste, even if it's small.
Even if we don't break the record. They have options. They can do it today and try to beat the world record, or they can delay it to another day and have an even better chance, but that decision is all up to them.
Let's do the small one, okay? We can't keep going back and forth. We can't keep playing with the weather.
It'll start raining again at any time now. I understand his concern. But this is the moment.
It's stopped raining. It's our only chance to do the experiment and break the record. If it was up to me, I would just do it today.
Guys, what do you think? Should we try the giant one? -Let's do it!
-Let's do it! Let's do it! Let's do it.
This is it. We have do it quickly, it's getting dark. And we have to be careful about safety, because we don't know how big it'll get.
-That one over there? -Yeah. Would you rather add the powder and mix it?
17KG OF POTASSIUM IODIDE It's safer, right? Okay then. 231L OF WATER Let's go, guys.
64L OF DISH SOAP 25L OF DYE 1080L OF HYDROGEN PEROXIDE We have a long rope to turn every bucket, so each of you will hold one small rope. But we have to pull it all together at the same time and pull it fast One, two, three. .
. Go! Guys, good afternoon!
We are here to try to break the record for largest fountain of elephant toothpaste. It will work. It sure will.
It's now or never. We have a break. It has to be now.
This is when I feel the most nervous. I'm shaking, it's happening. It has to work.
I came from far. Gigantic! It's nerve-wracking.
I'm really excited, because now, it's all or nothing. I think it will be huge. I expect the foam to pass this and get up to my head, so I dive into the foam.
I'll get to tell anyone that my favorite channel has beaten the world record. We spent everything we had. We put all of our ingredients there.
It might go wrong, the foam could go lopsided. We might not break the record, but it will be huge. That's for sure.
The largest elephant toothpaste in the world. It's now or never! -It's raining.
-We have to make this happen. Ready? -Yes!
-Yes! One, two, three. .
. Go! Gigantic!
It was gigantic! It's started raining, so now we have to hurry to measure it. We have to measure it.
I'm running in circles like a crazy person because we need to measure it. If it's not the largest, I don't know what is. The timing was perfect.
There was a person shooting right upfront to mark, but the smoke got so in the way. -Smoke! -Smoke!
We've been making videos for 12 years. We've done a lot of big things, but. .
. this is the first time we're trying for the biggest something in the world. But you don't get a great idea of its size just by looking at that mass.
I'm really nervous for the result to come out to celebrate with everyone. But now the adjudicator is out there with our engineer, doing the math. They're looking at the video, measuring it.
Fernando, please. I have to check the ingredients list. The foam is still warm.
It's been an hour. I don't know if we followed every rule, if we managed to take every photo at just the right time. I'm worried we might have gotten something wrong and the record will nullified because of it.
Those are the measurements we took. Considering a margin of error of less than 10% to be able to avoid any measuring mistake. Since the shape isn't a perfect spherical cap.
So, with the average measurements we took, we got this result. -So, this is the final result? -Yes.
We can make the official announcement, then. Thank you all for coming. Today we attempted to break the world record for the largest fountain of elephant toothpaste.
Every rule was followed, so I can say that the attempt is valid. The record to beat is 21. 4 cubic meters which was achieved in Canada, May 9th, 2019.
So, Manual do Mundo, the final measure taken today was. . .
275. 91 cubic meters. I'm so happy we did it!
We did it. We kicked the bucket. We'll kick it even harder from now on.
Manual do Mundo! -We rock! -We rock!
Iberê, I guess this van belongs to your kids. I’ll hang it in the living room. Babe, come on.
