[Captions by Y Translator] Kinetic sand is a weird combination
of fine grit colored sand and a rubberized polymer.
We wanted to see what happens
if you heat it up in a variety of ways.
Can you burn it?
Can you melt it?
What happens if you put it in a microwave?
[Music]
We've done some fun experiments with kinetic sand in the past
including casting metal into it in a few different ways.
And now we want to see
what happens if we apply heat really directly.
We've got five different methods
that we're gonna use to apply heat to our kinetic sand
and see what it does.
Here's the basic idea.
We've got some colors of kinetic sand,
and we're going to try applying heat to them in a few different ways.
We're gonna try our backyard foundry,
we'll try our arc furnace,
we'll see what happens if you boil kinetic sand,
microwave kinetic sand and hit it with a blowtorch.
First off, let's take some sand, put in a crucible,
and get it going in our backyard foundry.
Will the sand burn?
Will the sand actually melt?
Can we turn this into glass?
Let's find out.
[Music]
Sand in our crucible is,
I think it's actually on fire now.
Fair bit of flame coming up out of the crucible at this point.
It's, it's kind of fun
cause it's got like swirling smoke.
Well, then like the fire gets into two.
We've almost got
a little bit of fire tornado coming up out of here.
Okay, we've got a couple of multicolored sea creatures
here just sitting on a piece of fire brick.
We're gonna see what happens
if we go for a really direct approach with our heat.
We're gonna just hit him with a blowtorch and see
what happens to him.
We've got a blowtorch and our little sand creatures.
Wow!
As soon as the heat gets on that,
it's like the pink changes to purple.
And it actually goes away a little bit
when it cools down.
So once we've got gray,
I don't think there's any coming back from that.
I think it's pretty much ruined at that point.
Burned all the color and the polymer out of it.
Let's keep this going.
[Music]
Oh, That arm is gone, that arm is gone.
Starfish are supposed to be able to regrow arms,
but this might be too much for it.
[Music]
So here's the sand that got the most heat
on it and it's just completely a powder.
Over here some sand,
they get burned, but it's also still cohesive.
It's staying together a little bit.
Then in the very middle,
there's the part that still have their color.
So the color goes first and then the ability to hold together,
and then it's just powder.
[Music]
All right.
So we've got a glowing orange crucible
full of what appears to just be really hot sand at the moment.
Don't think we got much more results from that
although, a little bit on the side,
looks like maybe it vitrified.
We've melted glass in this same crucible before,
so it's hard to know what exactly it is we're looking at.
See if we can pour some of this out.
[Music]
Oh, that's cool, glowing orange glass powder.
[Music]
Some glass with embedded sand right here,
some very fine-grain sand too,
much more so than playground sand
or something like that.
[Music]
Yi-hi-hi, It works just right.
[Music]
This is cool.
So I'm just dripping water onto our sand
and our sand is extremely hot.
So as the water gets poured in,
it seeps down past the sand,
but then it keeps getting heated up and boiling away.
So it's just bubbling
underneath the super hot sand.
Overall though, I would say there is like none of the polymer left.
This is just sand at this point.
I'm gonna take our little castle mould
and fill it with some of our blue and green sand
and then we're going to try putting it in a microwave,
and see if that does anything to it.
[Music]
Still put a little longer.
[Music]
The plate that this is sitting on is now hot enough
that it's uncomfortable to touch but the sand itself...
[Music]
Not tasting, I'm just feeling it on something more sensitive.
It's warm.
It's not hot.
Really doesn't seem to heat up much
like it's definitely much warm on the bottom.
I think most of the heat
that it's experiencing, is coming up through the plate
at the bottom and into the sand,
but the microwave
doesn't seem to affect the sand very much at all.
Let's go for broke.
Just gonna put it in for three, four more minutes.
[Music]
Once again, the bottom is fairly warm,
but that is mostly from the plate,
which is very hot.
And the top of a sand is just kind of normal.
I've got a small pot of boiling water
and now let's see what happens if we boil a little sand castle.
[Music]
Here it goes.
[Music]
Don't see a lot going on with our sand that's
in our boiling water either.
It may have begun
to puddle just a little bit lose a tiny bit of definition,
but you can see
that a lot of the definition is actually still there.
All the little tiny stair steps,
that little crenellations on the top of the towers are
still quite visible.
It appears that on the inside, the water hasn't made it through.
So this stuff I think is kind of waterproof.
Outside is getting boiled
but inside is not really changing much.
Just let it run for a few more minutes.
You have started to see a result.
During enough time, in the water.
I did add some more water this had boiled quite low.
[Music]
Let's pour off the water and see how this stuff is.
[Music]
The water is slightly tinted green.
[Music]
Little hard to tell, but it doesn't feel
like it's acting the same.
[Music]
This is acting a lot more like wet sand,
and a lot less like kinetic sand.
I may have ruined it.
Let's do a side by side comparison.
Here's our kinetic sand unheated,
and our boiled kinetic sand.
[Music]
Not even the same color anymore, but close.
This is yellower.
So we definitely had to boil it for a little while
before we had an effect.
At first,
It didn't seem to change much but after about 10 minutes,
it seems to have completely ruined the effect.
We've tried some things
that heat it up our sand a fair amount,
but now we're going to try when that heats it up a lot more.
We're going to use our arc furnace
and see what happens.
Castle being made of not just built on sand
but literally being made of sand has collapsed a little bit
into our heart furnace.
That's okay.
[Music]
That right there is melted sand.
So it very quickly ruins the effect of the kinetic sand
and see like,
look at this digging down into it still burns,
still burns.
So that got hot enough to ruin our kinetic sand quickly
and our one little spot
where we had all of our heat concentrated,
we got it to melt and turn it into a crude form of glass.
Guys, that's it for today, but the fun doesn't end here.
We've always got more for you to see.
That box up at the top will take you directly to our last video.
You should go check that out.
The other box will show you
what YouTube thinks you should be watching next
and if you hit this bomb in the middle,
you'll be subscribed to our channel.
and that way you'll never miss a video.
Don't forget to ring that bell
and we will see you in the next one.
Talk to you then.
