Bombed to bloom | Mediateca de EducaMadrid

Run! Run! We must make space! 00:00:01

This is not safe! This is not safe! 00:00:03

Faster! Faster! Come on! 00:00:07

We made it! It's okay! 00:00:11

Amazing! Let's keep going. 00:00:17

It's done. 00:00:20

This is a tree of the Boundary of Lobations. 00:00:21

Just a few weeks ago, a war started in our country, 00:00:23

destroying the place we once knew. 00:00:25

Just today, it suddenly reached our place, 00:00:27

causing us to take shelter in this bunker. 00:00:29

Despite the devastation, our mission is clear. 00:00:30

We must find new ways to recover the soil of our plants. 00:00:32

which have been heavily contaminated by destructive materials found in the ancient variant vases. 00:00:34

With no freshness of soil, there would be no crops, no food, and no future for the worms caused by this conflict. 00:00:38

This situation is nothing but unfair. 00:00:42

As scientists, our duty is to solve this problem and find a way to recover the ecosystem we all share. 00:00:44

It's been three days since the bombing started, yet we still haven't found the answers to our questions. 00:00:52

The plants are dying, the soil is deteriorating, we have to act fast. 00:00:56

We must find a solution in order to help our plants and the future of our country. 00:00:58

Before the war started, we collected some soil samples. 00:01:01

We measured its pH and equals 10, which is neutral. 00:01:03

Now, after contamination, it has reached approximately 8.5. 00:01:05

This change doesn't allow the soil to support plants' life. 00:01:09

OK, let's start. 00:01:13

Since getting out is too dangerous 00:01:15

and we can't get rid of all of our contaminated bomb, 00:01:16

we decided that the best option was 00:01:18

to recreate the effects that the bombs have on the surface 00:01:19

by using ink or gesso. 00:01:22

The results we have obtained are clear. 00:01:24

After the exposure, the soil is no longer rich in water, 00:01:25

which makes the plants' living a little too suffer. 00:01:27

They resulted in an increase of the pH level. 00:01:29

Okay, it's on. 00:01:33

It's currently day five. 00:01:34

Today, after further research, we identified some substances that could be used as solution, 00:01:35

for example sodium percarbonate, which helps restore the oxygen levels in the zone, activated 00:01:38

carbon, which absorbs pollutants, vinegar, and a technique known as very-composed, which 00:01:42

uses the elements created by earthworms from the waste of the soil. 00:01:46

Now we're testing three different combinations to see which treatment works the best. 00:01:49

The first one, bismuth, won't be exposed to any chemicals and it will be watered as 00:01:52

normal. 00:01:56

Antimony will have ink added to its soil, and arsenic will have gasoline. 00:01:57

In the Moscow theorem, we will prepare a mixture of ink and gasoline for ink, and we will try to immunise a molecule. 00:02:02

Let's check if our hypothesis was correct by doing the pH test. 00:02:12

If the results resemble as the first ones we did, that means that our hypothesis was correct, and we can go on and continue with the last test. 00:02:15

If they are now higher, then we will have to generate a new hypothesis. 00:02:21

Now, let's do the pH test. 00:02:25

We did it! It seems that the survey search must work. In all cases except 9-0-0, it is the ground we tried to minimize, understanding whose soil is now icy. 00:02:27

Opportunity of 3.5. Now that the pH levels are almost back to normal, we are going to see if the soil is able to grow and sustain life again. 00:02:37

To profile our theories, we will try to grow grass in the now-rehabilitated soil. 00:02:44

We are glad to announce that after countless hours of testing and research, we've made it. Our experiment has worked successfully. 00:02:48

Our team has always been concerned about wash and flora being damaged during it. 00:02:57

Now, we are going to ask you for one last thing. 00:03:01

Please, help us spread the word about our results 00:03:04

and tell as many people as you can 00:03:06

that there's a way to repair the damage 00:03:08

and ensure a better future for everyone. 00:03:09

By putting our minds into practice, 00:03:11

we can make a difference. 00:03:13

Thank you so much for everyone who's watching, 00:03:15

for following our journey, 00:03:16
