To prove I'm a true Batman fan lets try branding...
Come on baby...
*skin sizzles*
So in our last video we showed how it's way
more effective to heat up a sword or a knife
red-hot by using a transformer by
resistive heating. That's where you put
tons of electricity tons of current
through metal and the metal actually
acts as a resistor which means it heats up
but did you know there's another way that
you could heat up a knife to red hot
it's something called induction heating
and it's completely wireless.
ho ho...
Woo!
Look how fast that is, that's way faster than
using any kind of propane torch.
Now resistive heating is way more efficient
because it is actually using all the
power turning that into heat in the
metal whereas there are some losses with
induction heater but induction heating
it's just really cool! So in order to
keep this video original for you guys
we're trying something new
have you guys ever seen a red-hot Batarang?
Now when we made these
batarangs last year we made them out of stainless steel, but unfortunately due to its
low ferrous content it doesn't heat well with
induction heating, so we made a new set out
of cold-rolled steel using our Tormach PCNC 440 milling machine.
But first I'm kind of hungry.
*sandwich making noises*
oh we just lost another inductive heater...
man these things are finicky and I didn't even short
time, it was literally just running by itself and
went up in smoke
unfortunately these induction heaters from
China are bit finicky and you can blow them
up pretty easily
we're not too sure why that one blew up
but we think it might have to do with
proximity to the steel table
we're not gonna yeah I think we're
actually heating the steel table
slightly with some of the inductive
field from the induction heater which is
why it overheated so we're gonna go back
to using a transformer for the rest of
experiment on the plus side this also
means we can use the stainless steel
batarangs!
*chuckles*
BATMANNNNN
Man we're gonna get a tan...
For anyone complaining that these videos aren't quite a
thousand degrees, ours definitely are...
thousand degrees can't really do the
experiment with half of batarang so
let's try that again but I'm gonna have
to remove the Batarang from the
transformer a bit quicker this time and
I'm going to keep this on this time one
molten batarang.
Annnnd... that's good!
Now it's probably safe to say that I'm the
first person on this planet to have
eaten marshmallow cooked by a batarang!
So in our last video we didn't have too
much luck popping popcorn so we're going to try
different this time, what the hell?
I'm not doing that...
Wow look at all the heat it's actually taking from it
There you have it guys, the most inefficient way
to cook popcorn!
slightly burnt...
so what a lot of these red-hot knife
videos lack is an actual temperature
measurement -- everyone says its 1000 degree
knife but no one actually shows like a
thermometer or anything, so we've actually
busted out the thermal camera, and we're going to
show exactly how hot these batarangs get.
hoooooo
that's probably going to melt soon -- oh yep, there it goes
So unfortunately, the thermal camera doesn't actually measure
up for that heat but judging by the fact
that we actually melted this batarang in
half and that steel has a melting point
of about 1,300 celsius that means these
batarangs are well over a thousand
degrees celsius and well over 2,000
degrees Fahrenheit, so this is a pretty
much double the red-hot knife videos.
Alright ready... and go... Alright, to prove I'm a true
Batman fan, let's try branding flesh.
Come on baby...
Enough of that let's try throwing this!
Two gloves this time!
How's my hair?
Irony!
This is proving to be rather challenging...
There we go!
Oh! It's going -- that's so cool!
Yes!!! Oh it's like molten on the other side...
How do we get it out...?
Hope you guys enjoyed that if you haven't been to the
Hacksmith channel before, we take fictional ideas
for movies, comics, and video games and
make real working prototypes -- just like
those batarangs we heated up.
