Liquid Metal Play Button Melts In Your Hand


check it out this is crazy my silver
play button is melting hey guys welcome
back now in this video I thought it’d be
fun to focus on the YouTube silver play
button if you start a channel in YouTube
and gain 100,000 subscribers youtube
will send you one of these it’s a silver
play button award to celebrate your
dedication and your success but the
funny thing is they’re not really made
of silver and over the years they’ve
gone through a number of size shape and
style changes as well so for this video
I thought it might be fun to try casting
a metal play button of our own only this
one will have some very quirky
characteristics this here is the play
button that I just created now it is a
little bit frosty because it’s been
sitting in the fridge overnight and
you’ll understand why in just a minute
but it is pure and solid metal we flip
it over and look at the back you can see
that shiny metallic surface and if I
drop it on the counter and here it makes
the clinking noise expect solid metal to
make but here’s the interesting thing if
you strike up a flame on a barbecue
lighter and hold it just under the
corner of the play button watch what
happens
[Music]
you can see that within a matter of
seconds the tip of our play button
starts melting off how crazy is that
look at that it’s melting off and
forming a little puddle of molten metal
in the bottom of our dish which is crazy
right isn’t it supposed to take an
insane amount of heat to melt solid
metal not just the flame from a barbecue
igniter but despite that fact our play
button is melting look its coating the
inner surface with liquid metal
we just ran it around that track now and
it’s leaving behind a residue that’s
really cool oops it just splashed right
all over my countertop
look at that it’s already hardened
wonderfully like peel that off with a
spoon that’s crazy
shiny so update guys we just use a small
flame from a BBQ igniter to actually
melt the tip off of our play button but
this next experiment is even cooler
I just want to fill up a glass with warm
water and now if we stir our play button
into it look what happens to the metal
now in just a second you’re going to see
the metal melts off the surface and
drips down in the bottom
[Music]
moulton shiny silver metal liquefied by
water that is pretty cool just like an
ice cube would dissolve in hot water
our metal play button is doing the same
you can see I’ve melted off quite a bit
of this metal here parts of it are still
liquid and dripping off the surface and
just when I wonder if I could break it
in half
surprisingly it is still very very solid
metal despite it melting off in my hands
as we go here so let’s talk for a second
about what we’ve been noticing here this
solid play button once it got in contact
with a flame would melt and little beads
of metal would start dripping off now
they dripped off into this dish and some
of it splattered onto the counter and
you can see we take something like a
spoon and just nudge at it the metal has
completely solidified and turns into a
type of foil almost like tin foil
[Music]
you hear that it’s screaming like when I
push into it it starts screaming but if
we swirl it into a glass of hot water
you can see the metal melts off and
collects at the bottom forming a molten
pool of shiny metallic metal and yes
this really is molten metal but here’s
the curious thing about it it’s not
actually hot enough to burn you now if
you haven’t figured it out by now the
metal that I used to create this play
button is gallium it’s number 31 on the
periodic table of elements and it’s got
one of the lowest melting points of all
the metals gallium is in group 13 of the
periodic table of elements because it
shares a lot of similar characteristics
to metals like aluminum and indium but
unlike those metals the melting point of
gallium is so low that you can actually
melt it with your body heat it’s
relatively safe to handle because
gallium is considered non-toxic however
it is extremely corrosive to other
metals like aluminum and steel now
interestingly enough gallium is not
found anywhere on earth in its natural
elemental state by itself the stuff that
we have here is a byproduct of mining
other metals like aluminum and zinc and
it’s extremely expensive the play button
I created here today cost me about $300
it’s quite heavy and look at this
slipper it cracks my fingers right onto
the counter because the counter is cold
you can see the bottom of this mass is
already solidifying it’s already getting
quite hard oh it’s still a little bit
liquid at top that’s crazy
it looks like it’s solid that some parts
is still liquid
world half solid half liquid
[Music]
stuffs got a really unique weight to it
it feels pretty heavy but it’s extremely
running at the same time if I jiggle it
back and forth I can actually feel the
waves of motion flowing through it
because they kind of come to hard stop
as they bounce up against one wall and
bounce back very cool OOP and extremely
runny oh boy yeah let’s do really that
just peels off
[Music]
[Applause]
[Music]
[Applause]
Oh get it this place right off now I got
my gallium on Amazon it’s very expensive
but I’ll put a link down in the
description in case you want to get some
yourself it comes in a container like
this and when you open it up it looks
like a solid chunk of oxidized metal
because that’s basically what it is but
to melt the stuff down it’s as easy as
driving some hot water and throwing it
in there for a few minutes or just using
a propane torch and gently licking the
sides and getting it to melt off that
way the cool thing about gallium is you
can use it over and over and over again
you can cast metal objects that are
still extremely hard but then with a
little hot water you can easily melt
them down liquefy them and catch
something else that’s interesting about
this if you look down there right now
you can see it’s kind of a dull gray
watch what happens if I heat it up and
stir it up a bit
[Music]
[Applause]
it’s still weird it’s like the surface
of the metal just stops but you can
still see the motion swirling around
there somehow it’s so interesting super
crazy well just wipe the slag like we
would normally do it’s ready to pour now
making my galleon play button was just
about as simple as you might think all I
did was take a little propane tour to
remastered and I melted down a chunk of
gallium into its liquid state then I
took one of these silicon play button
molds that I made a while ago and filled
it up and let it sit in the fridge
overnight I also found that the warmer
you get the gallium the shinier the
metal gets that’s pretty much it that
right there is how you make the world’s
first metal play button it’ll melt in
your hands so let’s summarize what we
just learned here today gallium is a
metal with a melting point so low you
can melt it in glass of hot water
you can also recast that metal into
nearly any shape you want and it still
has a look and hardness of other metals
like aluminum it’s very expensive
because it doesn’t naturally occur on
earth it’s a byproduct of mining metals
like aluminum and zinc and you can find
it on eBay well guys thanks for joining
us for this experiment today it has been
awesome hanging out with you they’ll be
looking for in the next video talk to
you then yeah oh yeah play the fire you
burn
