we wanted to find out all the differences

between Lay's and Walkers in the US and the UK.

This is "Food Wars."

We'll start with a quick note

to explain their different names.

Walkers used to be its own company

and was the most popular crisp brand in the UK.

Frito-Lay actually acquired Walkers in 1989,

but they decided to still use the brand name in the UK

so all that brand loyalty didn't go to waste.

In the UK, Walkers crisps come in five portion sizes.

A multipack 25-gram bag,

a 32.5-gram bag,

a 45-gram bag,

a 65-gram bag,

and a 175-gram sharing bag.

The smallest that's in the multipack bag is 28 grams.

Then we move up to a 78-gram bag,

a 226-gram bag,

and then our party-size bag, 368 grams.

That means our biggest bag is 110% larger

than the biggest bag in the UK.

A few other things to note.

In the UK, if you get a flavored bag,

it's the same weight as the ready-salted version.

Whereas in the US, our flavored bags

weigh less than the original-flavored bags.

Take this bag of salt and vinegar chips.

It weighs 7.75 ounces,

compared to the classic regular-salted 8-ounce bag.

Back in 2014, PepsiCo claimed the reason

there is a slightly higher price per ounce

for flavored chips is the added seasoning.

OK, before we continue,

they're telling us, "Weighs less, costs more

because we're adding more seasoning." Right, guys?

Well, I got a question for you, PepsiCo.

[grunting]

What does that say there?

Says "Lightly Salted."

So I understand this has less salt than these guys?

Huh.

Closer inspection: right there, 7 3/4 ounces.

Not the full 8.

If there's less seasoning and salt in here,

why is it a smaller ounce and a higher price?

They're stealing my salt!

Salt, literally the cheapest thing on the planet.

We have a whole ocean full of it,

and yet they're still skimping on it!

Your move, PepsiCo.

This 28-gram bag of chips supposedly has 15 chips in it,

according to Lay's website.

Well, they lied about the salt,

what else are they lying about?

I'm going to count the crisps

in this 25-gram bag for comparison.

These chips are demolished.

I feel like it's more than 15.

This is what we call the

stoner-math section of "Food Wars."

We do the math so you stoners don't have to.

All right. So, one, two.

That's a whole one.

Little peephole.

Absolute Frankenstein of a crisp, this.

Arguably not one put-together chip in here.

OK, let's just ...

that's a chip, that's a chip, right?

So, the issue there is that the crisps

are all vastly different sizes.

Like, this one, just one crisp, but it's tiny,

whereas this one, also one crisp, but way bigger.

And we've ended up with 22.

Of all the arbitrary things we do on this show,

this has to be the most arbitrary.

Wow, look at that, everyone!

They gave me an extra chip.

16 instead of 15.

The last thing we wanted to check

was how much air you're getting in your bags.

Walkers in the UK are kind of notorious

for seemingly underfilling the bags.

We're going to find the volume of the bag

and then the volume of the crisps inside

to find out just how much wasted space there is.

What I need to do is carefully open the bag

just enough to let the air out,

and then I'm going to try and powder these,

like just crush them as far as I can,

and then measure the volume of the powder in this thing.

First I gotta crumble it up.

[whispering] Crushing bags with Harry.

[bag crackling]

Oh, this is like ... [growls].

It's quite therapeutic.

It feels like I'm giving a massage.

Just, like, the world's worst massage.

I need something to kind of tamp it down,

'cause the air is stuck in there, so I'll just use,

oh, I don't know,

this pair of nunchucks!

Oh, yeah!

Now, step two is going to be

to find the volume of the bag itself.

So we're going to fill the bag with water

to try and find the volume.

Oh, God. Oh.

Tiny bit more.

Perfect.

Sarah: OK. We did it!

But now I have to get it in there

without spilling it everywhere.

Three, two, one, go.

[laughing]

Sarah: Oh, that is perfect!

Harry: Look at that!

That went pretty well.

We didn't spill water everywhere.

Oh, my God, it's, like, right to the top there.

That's crazy how that worked. OK.

Buchi and Wumi are making a triumphant return.

Go and watch the Oreos episode if you haven't already.

Some of that,

and then measure the rest.

Y'all brought number two!

[laughing] Oh, God.

Can you see the bits of stuff floating around in there?

So, according to my trusted friend

PercentageCalculator.net,

around 90% of a 25-gram Walkers bag is wasted space.

I don't know what the math is

I'm supposed to be figuring out, I forgot,

but whoever's editing this, take all those numbers,

and this is the conclusion.

Now, that air is actually there for a reason.

It's nitrogen gas, which helps preserve the chips

and also acts as a cushion

to stop them getting smashed in transit.

I mean, imagine what it'd be like

if it didn't have all that air in there.

So, as much air as there is in there,

it's actually vitally important.

If anything, they should put more air in these things,

'cause these things, they turn into dust.

Into dust!

Here are all the Walkers products from the UK

that you won't find in the US.

And here is everything you can only get in the US

and not in the UK.

I am losing my mind, let's go!

I want to start with a couple

of linguistic/stylistic differences

rather than anything else.

For example, in the UK,

we call our classic Walkers ready salted,

as opposed to original.

I believe this is a reference to the very old days of crisps

where what you would actually get

is just, like, a bag of plain crisps,

and then you would have to add your own salt.

These ones are ready salted.

You don't have to add any salt, it's already on there.

One stylistic difference that's worth pointing out

is that in the UK, our salt and vinegar chips are green.

I will say Walkers is kind of the only brand that does that.

And then we're on to some actual exclusive flavors.

We'll start with this one, which is cheese and onion.

Now, Americans don't have cheese and onion,

which might shock a few Brits

because it's one of the most popular flavors here.

Instead they have I think, like, cheddar and sour cream

and sour cream and onion.

It just ruins your breath.

Your breath smells so bad after these.

How did I get so lucky?

I love chips, I love different flavors,

I love trying new varieties, and I hate paying for it.

So this is perfect for me.

I'm going to start with a flavor

that I never even heard of, cheddar jalapeño.

Oh, my God!

I like the kick on these.

It reminds me of the cheddar and sour cream,

which I can't believe you guys don't have.

This flavor took over about 20 years ago,

and I don't know why it's so good, but it is good!

Love this flavor.

If I had to rank them though,

I'll put the jalapeño above that one,

the cheddar and sour cream.

Sour cream and onion, I don't even got to open these.

Sour cream and onion, classic flavor.

I mean, barbecue in America is amazing.

I mean, this is just a classic, classic flavor.

Oh, man. Fantastic.

But how does that compare to sweet Southern heat barbecue?

Southern heat!

Oh, yeah.

I put these above these.

Then we got honey barbecue.

How sweet is this one going to be?

You got greedy with the sweetness.

Ooh, chili lime.

Yeah, dude. I've never had these before.

Chilies and limes.

See that? Chilies, limes.

Fantastic combination.

Ooh, I don't know how I feel about these.

It's like, I wasn't into them before,

but now I kind of can't stop eating them.

Another iconic British flavor

that's also exclusive is prawn cocktail.

Brits became really obsessed with prawn cocktail

in, like, the '70s, I think it was.

It just became a sort of trendy thing

to serve at dinner parties.

I'm not mad about that, because it is a really tasty one.

It just kind of tastes tomatoey,

because it was usually served with

a tomato mayo-Worcestershire sauce combination.

Next we've got a personal favorite of mine,

which is Marmite crisps.

God, I love Marmite. Marmite is fantastic.

The slogan was, "You either love it or you hate it,"

and it does still ring true, I think, for most people.

I'm firmly in the love-it camp.

Bit of tang from the amount of salt that's in there.

Fantastic crisp.

Harry was nice enough to send me some of his UK exclusives,

which I'm going to look at right now.

Where do I want to start?

I guess all start — oh, no.

Marmite.

I don't get why people love Marmite.

Ugh!

I mean, it tastes exactly like ass.

I hear millennials like that,

so maybe that's a selling point for them.

They should actually be like, "Tastes like ass,"

'cause the kids are into that these days, but I am not.

Then we have a couple of meaty options,

which I'm surprised you guys don't have in the States.

We kind of love combining crisps and meat, as it seems,

starting with these roast chicken crisps.

Another meaty option is these, which is smoky bacon.

Then we have these ones,

which are tomato-ketchup-flavored Walkers.

In my opinion, prawn cocktail does ketchup

better than ketchup does ketchup.

And then for the last of our standard crisp flavors,

we have pickled onion.

Pickled onion's another thing

that's kind of iconic to British culture

in the same way that maybe prawn cocktail or Marmite are,

just 'cause it's quite traditional

to find a big jar of pickled onions or pickled eggs in pubs,

and you'd have one of those as a bar snack
