[Captions by Y Translator] We've done some fun stuff with dry ice in the past.
Today, we're going to kind of push that to a limit,
and see what happens if we drop a lot of dry ice
into some very hot water.
[Music]
We got a common request from YouTube user Sagar Parajuli
asking us to boil dry ice plzzzz.
Plzz.
To start out, we want to take a look at the difference
between putting dry ice in room temperature water
and boiling hot water.
See if we get a different result.
Here's the basic idea.
We'll take dry ice and water,
and see what gives us the best reaction,
and then scale that up.
Let's put in there for 30 minutes.
Just like 30.
Just until it boils over, and then we take it out.
30.
Has your microwave had a bowl of water explode inside it?
Calli is going to show you how to fix that,
because I don't know.
Apparently, she's microwave expert.
So the first thing you want to do is go to the store
that sell microwaves.
Pick one up...
And then you're done.
Yeah, that's it.
That's how you fix your microwave guys.
We're really good at this.
[Music]
Trying to just get two pieces that are kind of the same.
That's pretty close.
All right, you take one.
>> Got it. >> I'll take one.
So this one is super boiling hot,
and this one is just tap water.
Hot...
Not hot..
Room temperature.
That's the word.
All right, so we're going to drop these in the count of three,
and see if there's a difference.
1, 2, 3.
Gee, I wonder what the difference is.
There's this, there's a bit of a difference here.
So though dry ice and room temperature water,
it definitely still produces vapor as you can see.
So, the hot water is making the dry ice
is actually sublimate faster in this one.
But you're still getting bubbles in room temperature.
You're actually getting more bubbles.
So those were about the same size,
and now from a hot water,
we just have this tiny little chip floating around the surfaces,
which I'm trying to grab but it's running away from me.
Come here you.
So the cold water definitely last longer.
That's our dry ice left there.
And that's how dry ice left from the colder water.
So we are going
through our dry ice much faster with the hot water,
and that entertaining [inaudible]
Just vibrating on the counter.
So boiling hot water
definitely gets you a lot more of a reaction.
That's good.
There's one other thing I want to test though,
and that is the surface area
of the dry ice going into hot water.
Will the same quantity of dry ice give us a bigger reaction
if we crush it up into powder,
or is it better as a single block?
Let's find out.
Okay, these two chunks of dry ice are about the same size.
Now, I'm going to chop one of them up,
and just break it up until it's a really fine powder,
and the other one going to leave as a chunk.
[Music]
Nope.
It was so angry about that.
No, don't do that.
3, 2, 1.
[Music]
That is just cool.
So right at the very very beginning,
this had just a huge plume, and so quickly, it dissipated.
And now, we've just got
like this little low bubbling come out of it.
Yeah, but look at the way
it expands across the counter. >> It's already almost gone too.
I don't know I kind of--
Like I did, I did like the sudden explosive bit,
but I'm liking
how that just keeps pouring stuff out more and more.
So maybe what we need to do is both.
Just have like a large chunk,
and then also some powder for just
some extra explosiveness right at the very beginning.
But I think we also need to start scaling this up,
and you may notice there's a few sizes of pots here.
Which one are we going with?
I think we need to do...
Let's do them in order.
Let's do...
Small, medium, large.
[Music]
That's a terrible noise.
Okay, we've got our small pot.
That's reached a rolling boil,
and here we've got a good-sized chunk of dry ice as well,
as some smaller chunks,
and even some powdered bits down at the bottom.
We're just going to pour all of that in at once,
and see what kind of explosive reaction we get.
Whenever you're ready.
[Music]
It actually threw out a little bit of water with it.
Oh, good.
Boiling water everywhere.
Yeah.
That's actually warm.
That's really cool.
Oh, yeah.
The vapors coming off of this is quite warm.
It's really hard to put dry as vapor in your mouth,
because for one thing it's...
Like it's fizzy.
Like it makes your mouth fizzy.
But your body doesn't want to breathe it in.
So it's going to try and make you cough.
Like that.
Yeah, it gets into your throat at all, it's just...
Your body's just like, no, don't breathe this in.
You die from this.
This is the opposite of everything we wanted.
[Music]
There we go.
We're going to want to stand back a little farther
for the bigger...
For the bigger pot.
Yeah, we are.
That started throwing drops of water kind of right away.
I want to know
if the water is cool enough to touch.
Nope.
It's very...
It's very warm water.
>> It's like hot tub. >> It has definitely cool down a lot.
Should we chop up a bunch more?
Yes.
That was really cool to watch.
The little mini explosion and how much vapor we got,
but we weren't technically boiling the dry ice.
Not yet.
We put the dry ice into boiled water.
Let's try actually boiling it.
Let's see what it does.
All right, we got more water boiling on the stove.
We'll see if it's any different if we actually leave it
in the boiling water.
Oh good. It does that.
So that's pretty much the same reaction we're getting before.
So yeah, it's just
more consistent with what we had before.
I think it...
Yeah, it's probably slowing down,
or it's probably staying hot a little bit longer,
not cooling down quite as fast.
Although, you can see we already have a different reaction.
We're no longer getting that pillar rising
up to the ceiling.
So I think that means
that the dry ice is winning the fight
between hot and cold here.
So the water itself probably isn't even boiling anymore.
That's a good way to test it.
It's not.
Yeah, when I blow all the vapor out of the way, I can see
that there is bubbling right off of the chunk of dry ice,
but it's not boiling the water anymore.
Even though we have this stove turned as high as it goes.
So here it is,
the piece of dry ice that has been boiling.
And I would say
that it looks pretty much just like what it looked like
before it went in,
except now, it's a little bit smaller.
Not really any more brittle.
[Music]
So, boiling dry ice,
I mean you get a cool explosive effect
when it lands in the boiling water.
But as soon as it cools down, you're back to normal dry ice.
So I think with our scaled up experiments,
we will not leave things on the stove just
because it's splashed water out
with both of the tests we've done so far,
and I think we want to avoid splashing too much water
on the appliance and stuff.
So we're going to take our boiling water,
and same as we did with our first experiment,
we're gonna take them off the stove,
put them on the hot pad,
and then put the dry ice in over here.
[Music]
3, 2, 1.
[Music]
Oh, that is everywhere.
[Music]
Holy cow.
Cal, can you see me?
No.
Where are you?
Try and blow smoke ring in this.
I did.
Did you see it?
Yes. Good job.
[Music]
It's so warm and fizzy.
We got the same explosion
that we had before with the big chunks,
but now, we're just at that rolling sort of...
Filling, filling the room with vapor.
Kind of like the small chunks did.
And we should make sure that we have a door open,
because we are filling the room with carbon dioxide.
We don't want hypoxia.
Is that what this lightheadedness is?
Ah weird.
[Music]
So I'm thinking that for our our Mongo pot here,
we should probably take it outside.
Yeah, and not stand near it.
It's going to be a lot funnier inside though.
It's true.
[Music]
That's a big old pot of boiling water.
This is definitely safe.
Yeah.
All right, you take one handle.
I got it.
Ready?
3, 2, 1.
[Music]
I can't see anything yet.
Whoa, that is a weird sound dampening effect.
Like all the echo is gone.
I had no idea I was going to take a shower this morning.
I can't see anything.
It's just white.
Mark, can you see us?
I'm going back in.
I'm soaked.
Yeah, that did splash some boiling water.
That was...
Wow.
The ceiling.
Oh no.
That was definitely a good idea.
There's Mark.
Hey Mark, welcome back.
Only Mark went anywhere.
3, 2, 1.
[Music]
Thank you for this wonderful idea.
[Music]
There definitely is a temperature change.
That's insane.
[Music]
Oh my gosh. Did it--
It actually launched bit some dry ice too.
No, its-- Have you seen the floor?
I hadn't been able to see the floor.
We're soaking wet.
Let's get some towels.
So thanks Sagar for your suggestion.
