- Oh boy! (water steaming)
Oh boy!
(metallic grinding)
- Welcome back, What's Inside.
I'm Linc and this is dad,
and today we're gonna cut open some Yeti cups.
- What week is this Lincoln?
- Mug Week.
- Mug week, and this is the end of mug week, ha.
We could probably find a lot more cups in mines
but two out of the three of these
are the most requested mugs that we've had.
The self-stirring cup was something that nobody requested.
We just saw it and thought it looked awesome.
But what's funny is we went onto Amazon
and we typed in Yeti cup,
and I thought that I bought an actual Yeti cup.
Turns out,
I got this instead, Artic.
- [Dad] They look the same. - [Linc] They do.
- So what we did is about an hour ago,
we hurried and got in the car
and drove to one of our local stores
and they had entire rack full
of different sizes of Yeti cups.
So, we picked out the 20 ounce and the 30 ounce.
Keeps your drink as cold as science allows,
is what this one says.
This one makes some pretty strong claims on it.
They both say they're 18 by eight stainless steel
construction and they both say no sweat exteriors.
So, this is kind of a knock-off, I'm guessing.
We gonna do a little science experiment, for fun,
before we cut it open and see what's inside,
because these things are supposed to be so, so good.
You put it in your truck,
you're out working all day,
it's hot in the summertime,
your ice-cold soda is gonna stay ice cold
for the entire day, apparently.
- [Dad] So... - [Linc] Yeah.
- This is the Muggy-mug,
the unspillable cup, many people call it.
One that you put down and it won't do anything
and you lift it up,
and then I picked up the cheapest one that I could find
at the local store.
- The cheapest one.
- This one was like eight dollars.
16 ounce, 16 ounce, 20 ounce,
and then these twos are 30 ouncers.
- We're gonna put ice cold water in all five of these
and then we're gonna stick it in the oven
and test the temperatures and see what water holds the best.
(soft electronic music)
- So, during that whole time,
I filled up four of them with five things of ice
and Lincoln hasn't even...
Emptying out the only one he worked on.
- Who left this paper in here?
- Yeah.
- Four, five.
- Way to go Lincoln, nice job.
- I know how to count.
(upbeat electronic music)
- [Dad] Each one of them has water in it.
Yes, the 30 ouncers don't have that much in it,
but the same amount as these mugs.
It's around the same, 43 and six.
What about this guy?
So, they're all around the same.
Don't try this at home.
This could be super-dangerous.
- It could be, but it could be awesome too.
- No, no, no.
I'm telling them not to do it at home.
Don't tell them it's going to be awesome
because then they'll want to do it.
It will be awesome, but dangerous.
You could burn your house down.
You really could.
Let the competition begin!
Yes.
325 degrees,
20 minute torture test, convection bake.
Which mug is going to survive?
We're about four minutes into this test,
and I don't smell any plastic burning or melting.
That's good.
Okay, we've got a problem.
The unspillable mug just fell over.
Out of all the mugs,
Oh boy! (water steaming)
Oh boy!
Okay, unspillable mug.
It's just plastic so it's just totally melting
at the bottom.
- Oh, that's hot!
- Yeah, don't touch it.
What are you thinking?!?
(laughter)
- Any water left?
- Yeah, let's test it out.
A lot of the water got
- [Dad] Spilled out. - [Linc] Aw, it stinks!
It warmed up to 59,
or 15 degrees Celsius.
So, it definitely got warmer.
The lid for the Artic, check it out.
It sunk, it melted and sunk down into it.
The two Yetis are still pretty good on there.
I don't know if it's a knock-off or less quality.
I do find it interesting that the actual plastic lid melted
and dropped down in it before
either of the two Yetis.
When only went 20 minutes, but I think at 325 degrees
convection bake, this is a good enough gauge.
I need something else to get these out with.
This old rag.
- Lincoln!
Kids, don't follow Lincoln's example.
The Artic, fell down in it, and it probably stopped it
from melting.
It just warped it.
This is the Yeti.
(soft rhythmic music)
Woah!
That is impressive.
I can see four ice cubes and one piece of a fifth,
and the water is at 39 degrees,
or three degrees Celsius.
Does the Yeti cooler work?
Look at it, 16 ounce compared to this 16 ounce.
Three degrees on that one, Celsius,
this one instantly jumps,
13, 14, 15, 16.
The big Yeti under 40, 39,
which is four degrees Celsius, nice.
All right, this is the true test.
The Artic where we lost the plastic top,
that comes up on Amazon and type in Yeti.
Nine degrees Celsius, 48 degrees Fahrenheit.
So, what did we learn today?
- That Yeti cups are very good at keeping water cold.
- They do their job.
Even though, yeah, this thing fell in it,
and that's what made it hotter, possibly.
These ones were in the same temperature space
and it didn't fall in.
I don't know, I'm a believer.
I'm a believer of the Yetis.
- [Linc] The Yetis. - [Dad] Right?
- [Linc] Yeah. - [Dad] I like the Yetis.
I didn't like them before
because they were so much money,
and I felt like it might be a false claim,
but after our little not very scientific test,
I'm a believer.
But, let's cut them open now
and see what the inside looks like.
(metallic clanking)
We got the bottom off.
Now that I look at it,
it probably shouldn't have been that difficult,
and it looks like somebody took a Sharpie
and wrote on it.
Yeah, I think people do quality control
at different steps of the manufacturing process,
wrote "Oop, I fixed it."
- [Linc] Yeah. - [Dad] I think the hatchet
can do it, but this is some tough metal.
So, back at it hatchet.
(metallic clanking)
(air gushing)
It just made a noise like some gas came out of it.
(metallic clanking)
This thing is tough.
It's bullet-proof.
Actually, I bet it would be bullet-proof.
I hit it with a hatchet a million times.
We got barely through the outer layer.
We still haven't punctured the inside.
Like, if I would put water in here,
it would still just stay in there.
So, we're gonna upgrade our saw here,
and give it another go with something else
a little bit stronger.
(bang)
(saw whining)
- Oh, didn't want to have to break out that saw,
but the Yeti is tough.
- Woah!
- Look at the layers.
So there's a thick layer of metal.
Air in between made that loud hissing noise
once I hit the right spot with the hatchet,
and then the very bottom of it,
it has a lot of space in the bottom.
That's pretty well built for a cup
to drink ice cold beverages.
Man, if I wanted to keep my drink cold
and I was going somewhere hot,
I would probably get the Yeti cup
rather than just like a really cheap cup
that doesn't do its job very well.
Playing with all three of these cups,
if you haven't watched all three of our cup videos
that we posted this week, go watch them.
It was a ton of fun,
but, man, this thing is hard to get into.
I wouldn't recommend that you cut these things open.
Thanks again guys.
Let us know what else you'd like us to see what's inside
and what else you'd like us to cut open,
and we will continue to do the things
that you guys want us to do.
