look at that it’s soaked the wall that
was like 25 feet away from me hey guys
welcome back thanks for joining us today
on the king of random recently we got to
show you our flamethrower which shoots
flame up to 50 feet that was pretty
amazing but it’s a fairly expensive
project we’re going to do today is show
you how to make a smaller version of a
flamethrower that can be built for a lot
cheaper and just to give it an ironic
twist we’re going to be building it out
of a fire extinguisher this is actually
a pretty simple build here’s the
materials we’ll be using to make it a
fire extinguisher a Schrader valve a
hose clamp
a 1/4 inch brass hose adapter a
wind-resistant barbecue lighter and two
types of fuel we’ll be trying out some
lamp oil and some lighter fluid with all
of our parts gathered we’re ready to
start building our flamethrower and the
first step is to empty out the fire
extinguisher of what’s currently in it
this thing just pops right off these
chemical fire extinguishers are usually
full of a yellowish powder and I don’t
want to spray it inside because it’ll
fill the room and get on everything so
I’m going to take it outside I’m gonna
try and spray it into a plastic bag to
contain the mess
seems to be working alright alright that
is empty you can see our pressure meter
is now showing that this is empty
nothing left in it see what comes out
into this plastic bag I don’t really
want to breathe this anything there you
go that’s yellow powder now I know this
cap is something that screws on I’m just
not sure how hard it is to get it off oh
there we go not that hard apparently a
little bit of brute force and this will
just twist right off there you go we
have the nozzle that controls the flow
we’ve got threads that attach it to the
bottle and we have this pipe that will
feed whatever is in the bottom of the
tank up through into the nozzle before
we proceed let’s empty this out and wash
it a little bit so we have a clean tank
to work with oh wow there was a lot of
powder still in that hmm yellow dust
with the tank cleaned out it’s time to
attach the tire valve first I’m going to
screw this back on about as tightly as I
can to figure out which direction it’s
going to point when I’m using it all
right that’s on there pretty tight but I
want to add my tire valve on the
opposite side of where it’s pointing now
let’s take this back off so it doesn’t
get in the way while we’re drilling a
hole into our tank since this is a round
metal container it’s gonna be pretty
hard to drill right into the side so I’m
going to use a nail to give an
indentation that will help guide the
drill bit all right hopefully that
little dent will make it easier for my
drill bit to stay in place we need a
drill bit that is slightly smaller than
the widest portion of the rubber on the
valve I’m using a 1/2 inch drill bit
now we need to get the tire valve out
through the hole we just drilled since I
can’t reach my hand inside the bottle
I’m going to pass a string inside the
hole and out the neck of the bottle tie
that to the top of the tire valve and
try and pull it through
yeah there we go Bell is now attached
through the hole in place and hopefully
that’ll give us a nice tight seal that
will hold against any pressure we put in
at this point I want to test really
quick if the whole setup is going to
work so I’m going to fill it about
halfway with water install the valve
back on fill it up with some pressure
and try spraying it to see if it’s
working
all right that’s installed all right
that’s just about 80 psi right there
let’s try that out all right here goes
oh there you go that is a nice spray oh
and with less pressure it’s a less nice
spray that seems to be working so let’s
add on the other parts to turn this into
a flamethrower as you saw the water is
spraying out in kind of a cone shape
which i think is the intention with
these extinguishers they’re supposed to
put out fire over a larger area so it’s
better if the powder sprays out in a
sort of a cone however what we want is
more like a squirt gun for the water or
the fuel to spray out in a stream that
will then light on fire instead of just
going everywhere that’s the point of our
little brass connection here we’re going
to thread this into the nozzle to try
and narrow down the stream of water so
it doesn’t spray out as much now I’ve
seen these fire extinguishers where this
nozzle is plastic and in that case we
would probably be able to just drive our
little brass fitting down into it using
a pair of pliers
however this one’s made of metal so
first we’re going to have to tap it to
add some threads put a little bit of
thread tape on our brass fitting
with the brass fitting attached let’s do
one more test with water to see how the
spray has changed
all right let’s see if our flow is any
better now oh that’s way better got a
lot more distance it’s a much tighter
stream that’s what we’re looking for
right there with the bike valve
installed in the brass fitting on the
nozzle we have an excellent sprayer
let’s add a source of heat so that when
we fill it with fuel and spray it it’ll
turn into a flamethrower I’m going to
try to attach our wind resistant
barbecue lighter to the side of the tank
so that the flame is in the path of the
fuel will use our hose clamp around the
tank and the lighter and try and secure
it in place to make it easier to get the
hose clamp in place without also trying
to hold the lighter I’m gonna use the
little electrical tape to hold it in
place just for a second while I clamp it
down
at this point our spray should go right
through our flame so if we use some
flammable liquid hopefully we’ll get a
flamethrower we’re going to try two
different types of flammable liquid in
our flamethrower the first is lamp oil
and the second is lighter fluid the lamp
oil isn’t quite as flammable as the
lighter fluid but it’s a popular liquid
for using and breathing fire since I
think we’re gonna have a similar spray
from our flamethrower I want to try it
out I don’t want to try anything more
flammable than these I could put
gasoline in here and it would almost
certainly light on fire since we’re
using compressed air to power our
flamethrower here I don’t want to risk
an explosion by mixing it with gasoline
let’s test out our miniature
flamethrower some of you might recognize
this is the same spot where we test it
out our larger flamethrower I thought
it’d be a good idea to test out our mini
one in the same spot because it’s really
fireproof first we’ll try it with the
lamp oil which as I said is the same
stuff used for breathing fire most of
the time
perfect now we add pressure right just
over 80 psi so I’ll light the lighter
and then while the flame is going I’ll
press the trigger and see what happens
Oh a little hmm well I think this type
of flame doesn’t have enough heat and
fire coming off of it consistently to
light the oil so let’s try one more try
using lighter fluid and see if that’s a
little bit more flammable hopefully the
lighter fluid is a little bit more
flammable and we’ll work with our
lighter so I tried firing I got a little
bit of it to light and then it went out
I think that even though this is
supposed to be a windproof lighter just
the gentle breeze out there is blowing
it out watch this the amount I’m blowing
wouldn’t even come close to putting out
a birthday candle this is kind of sad
here goes
shooting right through the flame
well that was mediocre well as you saw
using our lighter as a heat source
didn’t work very well I think the
pressure from the oil flying out of the
fire extinguisher was enough to just
blow out the flame I have another method
that I want to try that I think will
hold up to the pressure of the oil a lot
better than the lighter instead of the
lighter we’re going to try using a lamp
wick I picked up a few of them at Hobby
Lobby for just a couple bucks to hold
our wick I have what’s called a faucet
supply tube it’s a small piece of
chromed copper tubing and since it’s
made of copper it’s very flexible we’re
going to use that to attach to the front
of our tank add a wick in front of it
and light that on fire this tube is a
little bit too long so let’s use a
hacksaw to cut it short I’m going to cut
this one so it’s about seven inches long
now I’m going to put the bottom two
inches of this pipe in a vise and
flatten them out
clearly if I leave the pipe straight the
flame is going to be in entirely the
wrong place but fortunately since this
is copper it does Bend very easily we
want the pipe straight in front of the
nozzle about an inch and a half in front
of it and maybe an inch below it now we
use our hose clamp again to secure that
in place all right that feels pretty
secure and just as a safety measure so
don’t scratch myself on it I’m going to
bend the end of the hose clamp over into
a bit of a loop now that we have our
tube attached to the fire extinguisher
let’s cut off about three inches of one
of our wicks take one end of your wick
and roll it up you want to fit this
rolled end into the copper pipe try to
fit one and a half to two inches of the
wick down inside the pipe leaving at
least an inch of it exposed now we’re
ready to test our flamethrower we’ll
soak the wick in either our oil or our
lighter fluid and that will be the
source of ignition for the flamethrower
we now have our new wick attached to our
fire extinguisher flamethrower so let’s
test it out again
we had better results in our first test
with the lighter fluid than with the
lamp oil so I think we’re gonna skip
using the lamp oil and just go straight
to the lighter fluid in this one however
before I do that there is another thing
I want to test and that’s using coffee
creamer this is a corn syrup a powder
that’s actually pretty flammable when
it’s separated out I’m gonna see what
happens if I put it into the fire
extinguisher and see if the pressure is
enough to drive the powder through the
nozzle coffee creamer torch in three two
one
that’s actually working pretty good all
right it’s already out of pressure but
that work that worked all right when it
was blowing full pressure it did sort of
seem to have so much pressure that the
coffee creamer was flying past the flame
so fast it couldn’t heat up but as the
pressure dropped and even if I just sort
of halfway pressed the trigger to lower
the pressure it was lighting up pretty
good and I think this might be a good
relatively safe way to do this since it
really doesn’t have a light flammable
liquid getting everywhere it’s probably
a little safer than lighter fluid all
right we had sort of mixed results using
the coffee creamer now let’s move on to
the lighter fluid and see if that works
any better all right three two one ha ha
I’ll work for a second then it worked
for another second that part in the
middle I’m not really sure what was
going on there but the beginning and end
worked pretty good I think what caused
the gap in the middle is that there was
too nice of a stream when it was first
starting there was enough high pressure
that it sort of aerosolized a little bit
and that caught on fire and then as the
pressure got lower it had just a nice
little stream and that wasn’t broken up
enough for it to really light on fire
and then as the liquid got low it
started getting air and liquid into the
tube again and once again it was air
sliced and was able to light alright
let’s try this with lighter fluid again
see if we can get some good distance on
it three two one
look at that it’s soaked the wall that
was like 25 feet away from me
oh that was beautiful
there we go all the pressure almost all
the liquid gone that was the wall is
still on fire it’s still got lighter
fluid soaking on it that’s pretty great
that is how you want it to work that was
a great little just spurt of fire that
went 25 30 feet away stuck to the wall
burning the whole time
that was beautiful it’s on fire put it
out
I caught the ceiling on fire that made a
really cool noise too
yeah there you have it that is how you
can make your very own flamethrower out
of a fire extinguisher which seems a
little ironic but it works really well
if you use the right fuel this thing can
shoot pretty good and it lights on fire
beautifully we tried using coffee
creamer and got mixed results I think
the biggest problem is that we switched
between using oil and lighter fluid and
then the powdered coffee creamer and I
think it kind of got gummed up so if
you’re gonna use coffee creamer just use
coffee creamer don’t switch between the
two unless you have a very good way to
clean and dry it completely lighter
fluid worked great as a fuel this whole
bottle cost about four bucks at Walmart
and when you only fill a fire
extinguisher halfway which I found works
very well you can get four or five
different firings out of this thing it’s
all pressure just by using a bike pump
and I got best results when I pumped it
as high as 95 psi I got a really good
distance and I got a really good spray
of the droplets that still traveled
quite a ways this thing fired almost as
far as the full-sized flamethrower once
again if you’re going to build yourself
a flamethrower
don’t be stupid about it make sure
you’re wearing protective clothing don’t
point it at anything that’s alive don’t
point it at anything that’s gonna light
on fire unless it’s in a carefully
controlled location always make sure you
have the proper equipment to put out any
fires that you start while you’re using
it even if those fires are exactly where
you want them to be you want to be sure
you can put them out in a moment’s
notice if you need to there’s been a
really fun project that’s easy to do and
doesn’t take much time at all this
doesn’t have quite the same flame output
as the full-sized flamethrower but it’s
a lot easier and much cheaper to build
if you’ve got any great ideas if
something that really needs to be shot
out with a flamethrower let us know down
in the comments thanks for joining us
for this project today and we’ll see you
in the next one talk to you then I did
say it’s used for breathing fire
hey guys I hope you’re enjoying these
new videos with Nate as much as I am
he’s got some phenomenal talent when it
comes to building and crafting and he
really loves what he does
give him some validation if you agree
and I’ll see you the next video
