today we’re going to take some of this
weirdly liquid weirdly solid silly putty
and see if we can use it as a mold for
casting metal
YouTube user permit on weed says now
cast into silly putty this comment has
more thumbs up than I think I’ve ever
seen on one of our videos at almost 2000
probably is at 2000 by now so we’re
gonna do that we’ve got a bunch of silly
putty and we are going to try casting
molten metal in silly putty the premise
is simple we’re going to empty out all
of these eggs smush all the silly putty
together into a big blob press something
into it to turn the silly putty into a
mold and then try to fill that cavity
with two different types of molten metal
let’s start opening these eggs I
remember when I was an egg that’s a lot
well this is the most silly putty that I
have ever had at once try and squish
this all into a ball I don’t want to mix
it because I kind of like the separate
colors but I do need to combine it so
I’ll join together pretty well now I
want to try and roll it into a ball and
see how it bounces that kind of worked
then made a ball it bounces oh it’s
popping apart the seams are letting go
probably just need to let it sit for
like an hour to really bond everywhere
but back I’m not gonna do that right now
so let’s try turning this into a mold
that we can cast molten metal in the
first time we did this we used a 3d
print of grants face well today we have
a 3d print of my face and I think it’s
only fair that we try doing the same
thing with this
[Music]
I thought our silly putty did a really
good job of taking our impression of
mini-me
but unfortunately silly putty is not
quite solid in fact that’s what’s kind
of cool about it but in this case it
meant that the gallium which is quite
heavy was just pressing down on it as a
liquid for a good amount of time the
gallium was really barely over its
melting temperature but it takes quite a
while for it to fully solidify and in
the time-lapse you’re able to see that
just sort of smooshed everything down
and eventually pushed the silly putty
and broke free and spilled onto our
table and so now what we have is this
just blob that really doesn’t resemble
my face even a little bit peel this up
and see what kind of shapes we’ve got
okay so we have the shape of
crystallized gallium it does form some
cool geometric looking shapes and that
made a cool dent right into our silly
putty I don’t see any remnant of my face
in that a nice smooth surface that once
again there’s zero resemblance to the
sweatshirt that I had on here as casting
goes I would say this is one of our
worst failures ever zero resemblance
like just none whatsoever to what it was
supposed to be part of the problem of
course was that it took so long to
solidify and so I think we now need to
do another test with a different metal
and for that we’re going to move on to
aluminum so let’s fire up our furnace
melt some aluminum press this little
face down into the silly putty a second
time and then pour some 2,000 degree
molten metal down into it and see what
happens to silly putty under those
conditions guys I got to admit I am NOT
very hopeful that this is gonna turn out
our aluminum is melted and ready so
we’re now going to press the little
plastic mini-me down into the silly
putty make a new mold pull out our
molten aluminum pour it in and see how
the silly putty fares against our very
[Music]
alright there’s me decent mold one and
immediately lit on fire back off a
little bit in case it decides to start
spurting and looming them it’s on fire
yo oh the aluminum is still molten silly
putty is getting ruined oh we’ve got
some good drip äj– going on
as well our putty is melting you might
break down the walls that are holding in
the aluminum we’ll see I don’t know if
the aluminum is quite liquid enough to
run it so this is kind of interesting
your aluminum has now been re covered in
almost all of it by the burning silly
putty there’s one spot here still
exposed but there’s actually sort of a
bubble over it watch this I can blow it
out briefly and then the heat just
our aluminum has now cooled down well
I’m not gonna say that’s a good casting
but amazingly it is a better casting
than the gallium did a fantastic job of
lighting our silly putty on fire and
then just melting it really nice and
liquid and full of burnt silly putty ash
here it’s nice a little scoop of not
silly putty I’m trying to see if the
silly putty that got melted so it was
really runny will sort of reconstitute
as it cools down and return to normal
silly putty so far it seems like it is
actually it’s still very warm so it’s a
little softer than it was before but
it’s acting pretty much how you would
expect silly putty to act I would say it
looks like you can melt and re solidify
silly putty as much as it ever gets
I didn’t work and it smells bad mmm
burning plasticky smell so not all of
this silly putty is ruined but I don’t
think I can separate the Unruh and silly
putty from the ruined silly putty so for
that reason this might all just be blind
casting metal into silly putty thank you
for your suggestion Kermit on weed as
you can see it did not work we tried
gallium which is like the coolest
casting we can do and it still took so
long to completely solidify that it just
smooshed all the silly putty out and ran
and I do think this is probably the
worst casting we have ever got of
anything no one would ever be able to
look at that and guess that it was even
supposed to be a cast of a small person
like a bust or anything like that the
aluminum also bad but I think many
people would at least look at that and
say like oh that kind of looks like a
deformed outline of a human bust shape
like you you can see there’s a head and
the shoulders in a little bit of the
chest whereas with the gallium there’s
just three puddles and some geometric
shapes that have formed in them none of
which look anything like little plastic
me thank you guys for sending in your
questions now it’s time to give you some
answers alright we’ve got a question
here from at Seth burrow who is asking
does Nate have his own Twitter handle or
does use the king of random Twitter
handle the real answer to this one Seth
is that I don’t have Twitter I don’t use
Twitter
I don’t tweet I rarely read tweets and
it’s something that I probably should
get into but I think I tried it once
about four or five years ago and I
realized I did not have anything worth
tweeting about so I just I tweeted like
once and I was like well I don’t know
why I’m doing this this is just like
screaming off the edge of a cliff and no
one’s listening and I didn’t really see
much point in continuing to tweet in
that situation maybe now I’m in a
position where more people would be
interested in what I’m doing what I’m
saying and especially if I were giving
commentary on some of the videos or some
of the projects or some of my ideas or
if I wanted to get more ideas so I
should probably jump back on Twitter but
at the moment I have no Twitter sorry
guys thanks for watching but that’s not
all that box up at the top will take you
directly to our last video you should go
check that one out the other box to show
you what YouTube thinks you should be
watching next and if you haven’t
subscribed yet just hit this bomb to get
in the clubs and that way you’ll never
miss out on the fun don’t forget to ring
that Bell and we will see you next one talk to you then
