This 3D printed foot is helping scientists solve one of the World Cup's biggest logistical challenges:
2
making the grass pitch feel the same at every stadium.
3
We're simulating a 168 -pound soccer player, which is the average weight of the last two men's World Cups.
4
Here at the University of Tennessee, turf grass researcher John Sorokin has spent the last seven years preparing North America to host the world's biggest sporting event.
5
A World Cup pitch is one that's going to be uniform, consistent, aesthetically pleasing, and hopefully not talked about at the end of the game.
6
But that's easier said than done.
7
The 2026 World Cup will be played across 16 cities in Mexico, the United States, and Canada,
8
with different climates, elevations, and the world's largest and stadium designs, all of which affect how grass grows and performs.
9
Grass is a living organism.
10
You abuse it, it will die.
11
And once the tournament begins, there are no do -overs.
12
The field has to withstand weeks of matches while remaining safe, consistent and camera ready for billions of viewers around the world.
13
That's why FIFA has invested more than five million dollars into John's grass testing operation.
14
So how is World Cup grass created?
15
And what does it take to keep 16 pitches tournament -ready across three countries?
16
It's a month before the 2026 World Cup kickoff, and John and his staff of more than a dozen researchers are still busy in their Tennessee lab.
17
Since 2021, they've run more than 170 tests to solve a crucial problem.
18
How do you make a field in Vancouver play the same as one in Miami?
19
All World Cup fields have to have a natural grass surface because FIFA wants every pitch to feel the same.
20
So when a team plays in Miami, for instance, on Bermuda grass, and they go to their next game in Boston on Blue Rye, it's going to be the same feel afoot.
21
To make that possible, John invented the Flex device, a kind of crash test dummy for soccer fields that measures how firm,
22
consistent, and safe a surface really is.
23
All 16 stadiums will have one of these. to the turf.
24
Sensors measure how the surface responds.
25
And we can go across an entire pitch and look at 77 locations
26
and come up with like a heat map and look at the variability of that surface.
27
If one area is too soft, too hard or too slippery, Stadium crews can adjust the field before players ever step on it.
28
Players are going to get hurt no matter what sometimes, but we want to lessen that likelihood that it's a result of the interaction with the surface.
29
Keeping players safe is only part of the challenge.
30
The ball has to roll and bounce the same way too.
31
Even small differences in the grass can change the speed of the ball or the angle of a bounce.
32
something Argentina's players complained about after a 2024 game in Atlanta.
33
So they use this machine to fire soccer balls at the turf at different speeds and angles.
34
Recreating everything from a simple pass to a shot on goal.
35
It comes in at a 17 degree angle
36
and we don't want it to come up at more than a 14 degree angle as it goes in.
37
as we launch it.
38
What we would normally have is high speed cameras, radar guns.
39
Thank you.
40
The measurements help crews fine -tune how each field is mowed, watered and maintained, so the ball comes off the surface at a consistent speed and angle.
41
But keeping the grass the same gets a lot harder when there's no sunlight.
42
The hardest climates and conditions are going to be the indoor stadiums, right?
43
We have to rely on 100 % grow light situations because there's going to be no sunlight to help them grow.
44
Without natural sunlight, the grass can weaken,
45
recover more slowly, and be less resilient FIFA helped build this multi -million dollar research facility.
46
So FIFA built a simulator dome that has grow lights to simulate those five stadiums.
47
So we can grow grass inside with LED lights to simulate the sun.
48
Each of these 12 bays mimics a different World Cup stadium.
49
Some recreate fully enclosed venues, like Atlanta's Mercedes -Benz Stadium, while others replicate partial sunlight conditions, like at SoFi in Los Angeles.
50
That helps researchers see how different grasses perform long before they're installed in a World Cup venue.
51
simulate wear and tear.
52
If you look down, it's got a roller, then we put soccer cleat studs on it.
53
And when we go back and forth on the grass, we can simulate the cleat marks and the traffic.
54
And this is how we simulate traffic on our individual plots.
55
The goal isn't just to figure out which grass grows best.
56
It's to learn how each field should be managed, such as lighting and treatment schedules.
57
Now the pitch will recover between matches.
58
After years of research, the team landed on a game plan.
59
Kentucky bluegrass and ryegrass for cooler climates and indoor stadiums, and bermudagrass for cities with warmer weather.
60
Which should be mowed at a slightly lower height and it grows different than the cool season grass, but they're very common grasses you might have on a golf course, home lawn or sports field anywhere.
61
but we've just intensified the management to make it fit for World Cup soccer.
62
The actual game pitches are grown on 11 farms across North America.
63
They're planted on top of plastic sheets to protect the grasses roots, so they can be transplanted into stadiums.
64
What happens is the roots hit that plastic and they don't penetrate the plastic so they grow laterally.
65
This is an example of a small piece of the sod growing on plastic.
66
the plant by cutting off its roots.
67
-Harvesting enough for one pitch takes about a day.
68
-You roll it up off of the plastic, and you can cut it like a pizza, and all those roots are intact.
69
-Refrigerated trucks arrive at farms in the middle of the night to avoid traffic.
70
After being harvested in North Carolina, one pitch is hauled 12 hours north to New Jersey.
71
It's headed to MetLife Stadium, home to the World Cup Final, which will make it the most scrutinized field in the tournament.
72
In 2022, one and a half billion people watched the Cup Final, roughly 18 % of the entire world population.
73
Once the convoy of 27 trucks arrives, Workers spend two days installing the pitch on top of a base layer of sand.
74
using rakes and asphalt rollers to level and stabilize the surface.
75
So as it rains, that sand can drain really well.
76
The following week, a Zamboni -like machine will inject millions of artificial fibers deep into the sand.
77
So the natural grass roots can intertwine with them.
78
They come in with the machine and stitch in these fibers.
79
They act like rebar to stabilize the sand.
80
95 % of the surface is going to be natural grass, and those fibers are below the canopy of the grass.
81
So when a player runs and slides, they're not touching any of the fibers.
82
There's a lot of layers that go into it.
83
Kind of like a parfait.
84
Crews mow daily, monitor moisture, and re -roll the surface after every match.
85
So if you watch a World Cup game, you'll see just before the game They'll have the sprinklers on and water the whole field and get the grass wet.
86
They'll turn the irrigation on again at halftime just before the players come out, get the grass wet again.
87
And that helps the ball skip so it doesn't bounce too high.
88
And it helps with the performance playability of the game, the speed of the game, and the quality of the game.
89
And some of John's students will be there helping manage the fields in person.
90
We've had a student that started working on this as a high school student.
91
Now he's a freshman at the University of Tennessee.
92
And this summer he's going to go work in Houston for one of the host cities.
93
And that's the nice thing about this is the people that are all involved, love what they're doing.
94
It's not work for them.
95
This is a passion.

Phương Pháp Shadowing Là Gì?
Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
