(voice humming gently)
-: Hey, everybody! My name's Elias.
-: And I'm Alex.
-: We're from Bilingual Montessori School of Lund
in Sweden.
-: We will show you our new revolutionary invention,
the Pac Pod.
Both: Woo!
(light cheerful music)
-: We have created an underwater submarine.
It's collecting junk with a microscopic net.
-: Of course, this is only a prototype,
but when we're gonna build the real thing,
it'll have the same mechanic
and the same features.
Elias: And if we will improve it
time and time again,
and it will be just perfect.
-: Imagine waking up in a boat.
Elias: You thought the river would be filled
with junk and death.
Alex: But to your surprise,
it seems like it's totally clean
with some cute fish swimming
and one Pac Pod recharging around in the river instead.
Elias: You realize that we still have a chance
to survive climate change
as long as everyone helps.
Alex: Suddenly, you wake up
but this time in your bed,
knowing what you must create.
-: We have programmed a video game to,
in a fun way,
inspire small kids to make them learn
that we should be careful for our seas,
as the sea is responsible
for about 70% of the oxygen
produced in the atmosphere.
-: If we teach kids at the age of seven or eight,
we will give the new generation a fresh start
as they might have greater ideas.
Maybe the jurors is wondering
why we should win this competition?
-: (chuckles) Well, that's simple,
because we have a revolutionary idea
and our project is beautiful.
-: Yeah, it is.
(gentle upbeat music)
As you can see,
this is extremely symmetrical and sturdy.
(gentle upbeat music)
Thanks to the energy principle,
the Pac Pod will drag itself forward
due to the water resistance.
The mass of the Pac Pod is lower
than the water resistant.
The Pac Pod has a battery-
-: About here.
-: which creates deep sound in the ocean.
Deep sound are one of the easiest way
to scare off fish
before the propellers might kill them
and to not lead them into the net.
-: The microscopic net is so thin
that it will capture microscopic plastics
which is a major problem in our ecosystems.
-: Microplastic does not only bring disease to the fish,
but it also lowers the chance of corals to survive
due to increase of carbon dioxide in the ear.
Well, how does the battery get its energy though?
-: Well, the battery,
it gets its energy from having a solar panel here
and it creates an electric current
when the sun comes up,
as the water is heated
so the whole submarine is lifted to the surface
which brings energy to the battery.
(gentle upbeat music)
We have created four cogwheels interacting with each other
for both the x and the y-axis
which makes the propellers,
the two propellers,
spin as they are forcing the Pac Pod to go forward.
(gentle upbeat music)
This is a great example of what you call STEAM education,
as it includes
-: Science-
-: Technology-
-: Engineering-
-: Arts-
-: And Mathematics at the same time.
(gentle upbeat music)
So now you know everything you need to know
about the Pac Pod.
-: Help us save the world-
Both: And vote for us, woo!
Narrator: Alex and Elias invite you to try the video game
they designed for this project
by clicking on the link in this video description.
Not only is it fun to play
but it also raises consciousness
about the fact that plastic is a real-world problem
that needs to be addressed immediately
if we want to reach the United Nations Global Goals.
Thank you very much,
and don't forget to have fun
and vote for the Pac Pod.
