in today’s video we’re going to take a
look at a few different methods for how
to fill bubbles with fuel so you can
light them on fire in the past we’ve
shown you a fun way to make bubbles that
you can hold on your hand and light on
fire this is just a little bit of bubble
soap diluted with some water and a can
of butane that I’m just turning upside
down and pressing onto the bottom of the
bowl that releases the butane it forms
bubbles in the soap and then scoop them
up onto your hand and light them on fire
it’s a cool trick that when you do it
correctly is not all that dangerous
although of course you still need to be
very sure that you’re being careful but
it’s not quite what you might imagine if
you think of fire bubbles it is bubbles
and they can be lit on fire but we
wanted to see if we could do something a
little bit different I was hoping that I
could take an actual bubble machine and
modify it so that instead of just
blowing normal bubbles it blew bubbles
full of a fuel so you could then light
the bubbles on fire I’m going to walk
you through the process I went through
as I explored whether or not this was a
viable project on the back of the bubble
machine there’s a small fan that blows
air through the machine until it comes
out the front a little circle of bubble
wands dips down into some soap rotates
around and ends up right in front of the
fan that’s where the bubbles are all
blown out so my thought was that if we
could isolate the air intake and flood
that with fuel it would just start
blowing fuel filled bubbles out of the
front like with the bath of bubbles the
plan was to use butane as a fuel a
butane canister is cheap and we know
that it doesn’t just destroy bubbles on
contact with them there’s probably
several types of fuel that are like that
but we already know that mutate works so
that’s the one I wanted to try so how to
direct the butane from our little
canister onto the back of our bubble
machine well what I came up with was it
was gloves I decided to try using one of
these rubber gloves to see if I could
attach it onto the back of the fan and
then to just use one of the fingers as a
fill point for the butane here so first
step is use some tape and tape it down
that’s a glove just tape down over the
entire air intake of this bubble
dispenser and now at this point if I hit
this button it will actually suck some
of the air out of the glove and it on so
we know that the air intake is trying to
pull air from out of the glove that’s
what we want and now we need to attach
the other end of this glove to our
butane container to do that I’m just
gonna stab or cut a very small hole in
the tip of one of the fingers and then
I’m gonna just attach it around the
nozzle okay we now have our nozzle
attached to a finger of a glove and the
rest of the glove is attached to the air
intake of the fan see if we can I need
to elevate this a little bit more
alright for my workshop I have one of
these just sitting there so I’m gonna
use this the goal is to elevate the
bubble machine just enough that I’m not
pinging the connection between the glove
in the butene so it has a better chance
of filling correctly and not just
getting trapped in there alright let’s
see what happens if I grab the nozzle
and press down on it the glove seems to
inflate just a tiny tiny bit you see the
but most of the glove doesn’t and I’m
pretty sure that’s actually just because
it’s going all the way through the glove
through the fan and coming out in the
front of the bubble machine I have a I
think an effective if somewhat dumb way
to test that set this right oh I think
that’s test confirmed right there enough
butane had just settled around here that
it lit on fire but you can see that it
becomes flammable when I press down on
here butane is traveling through so now
the test is to see what happens if we
turn on the machine while we’re pushing
down on the butane nozzle will we get
well it was definitely flammable it was
definitely taking the fuel from the
canister and blowing it out in the air
but you probably noticed they didn’t
actually successfully make any bubbles
see the bubble machine works by just
blowing a fan constantly and then the
circular bubble wand moves the different
bubble wand heads in front of the fan
and that’s where all the bubbles come
out but it doesn’t only blow the air
when the wand is right in front of the
fan it’s constantly blowing it out in
between every one of these bubble wands
there’s a lot of space if you try and
let the bubbles anywhere close to the
machine you have a very real chance of
just hitting the stoichiometry where the
fuel and the air are mixed together just
right to go up in a big old fireball I
think it would need to be something a
lot more precise to be a fully automated
machine something that dips a bubble
wand into bubbles puts in front of a
nozzle a carefully shaped small volume
nozzle that’s just gonna blow the fuel
right into the bubble one instead of
just blanket spraying fuel everywhere
and hoping it catches some bubbles as
they move by so moving on from using the
pre-made bubble machine I still liked
the idea of getting bubbles blown
through a bubble wand of some sort so I
wanted to try a slightly different
method that did not use the bubble
machine this bubble soap came with this
gnarly bubble wand that does a pretty
good job of making some good sized
bubbles so I thought maybe I could
modify a butane canister so if we just
blow bubbles through here those good
bubbles
I like those bubbles so I wanted a way
to direct the butane sideways but by
leaving the canister straight up and
down and that kind of made me think of a
can of spray-paint cans of spray paint
or up and down the nozzles on the top
paint comes out sideways how perfect
that’s just a really important I do have
an extra spray paint nozzle from an
empty can of spray paint this obviously
it was black spray paint and it fits
fairly closely on top of our butane
canister it’s kind of loose still it
spins but even with it spinning and
loose like that if I press down on the
nozzle I can feel the butane coming out
the front I think there’s also quite a
bit leaking out the bottom because as I
said it’s not a perfect seal so what we
want to do is attach this nozzle onto
the butane canister a little bit more
permanently and to do that we’re going
to use some two-part epoxy we’re gonna
mix up a little bit of this apply it on
the little
the nozzle here and then put our cap on
and really try and make sure that we get
a nice tight seal so there won’t be any
gaps and no leaking fuel except out the
front make our epoxy and start applying
it and of course we want to make sure
that it doesn’t go all the way up onto
the top of the nozzle because that would
block it up and we do not want to block
it up we just want to stop it from
coming out the sides so we choose where
it comes out put that in and I’m just
going to twist it back and forth to try
and get that epoxy to bond on everywhere
in a circle but now it’s making contact
all the way around so now I’m going to
flip it back right side up because I
don’t want to have any epoxy
accidentally running down the nozzle and
just filling and blocking it all up so
right now that should be in a spot where
we’ll be attacked and form a seal all
the way around but it should leave the
nozzle open to spraying once the epoxy
is cured it’s been a few minutes and the
epoxy is cured so we have a nozzle on
top of our butane canister and I believe
we have butane only coming out of the
nozzle and not leaking out the bottom
plenty of butane coming out the front
but I don’t see anything spraying out
the gap here I’d call that a success
let’s see if we can use this butane
those are bubbles blown with the butane
canister so one of the main questions is
whether or not we can get enough butane
into these bubbles for them to actually
be flammable it could be that the
Bernoulli effect is causing there to be
so much air inside the bubbles that it
no longer is a flammable level of fuel
here’s a little bit of the science
behind what might be happening the
Bernoulli effect is something that
occurs with high velocity fluids when
something like a stream of air or
gaseous fuel is moving really quickly it
creates a low-pressure area pressure
always tries to move from high to low
and so all of the air outside of the
low-pressure zone will try and rush in
to fill the low-pressure zone which
means that air would get pulled through
the bubble wand into the bubble along
with the fuel seems logical to me that
the best way to test if there’s enough
butane is to try and light them on fire
let’s give it a shot
ideally this isn’t a one-person activity
but I’m gonna try and make it work
anyway I have here a little party
sparkler I’m going to light the party
sparkler I’m going to blow some bubbles
using the butane canister set that down
quickly try and grab the sparkler and
see if I can ignite the bubbles before
we need to stop changing come back oh
some of those worked it might have been
really hard to see on camera cause it’s
daylight and it’s just a small little
flame but those ignited the sparklers
have been lighting off some of the
bubbles but they don’t do as good of a
job as I think just using the torch
might do so I’m gonna try just lighting
the torch and blowing some bubbles and
trying to light it off with that might
work a little bit better
whoo yeah what I think I’m getting the
hang of what does work if I don’t press
down quite as much letting out the
butane in a slower stream it doesn’t pop
the bubble as often plus the pressure
difference between inside the bubble and
outside the bubble is lower so we get
less air and more butane which is more
flammable this is working okay actually
a little better than I thought it would
but it’s really hard to see in the
daylight I think we need to go to night
okay there we go that’s better we should
now be able to see if things are
actually lighting on fire
let’s give it another try ooh I saw a
little flame
ooh that was exciting all right since I
only have two hands I got my friend
Keith to fill in he’s got an extra hand
he’s gonna hold the torch I’m gonna make
the bubbles hopefully we won’t light
each other on fire we’ll see it’s like
whack-a-mole
packing them all not so close I will
[Applause]
he’s in his 30s folks I’m an adult well
I’m the one blowing bubbles so you know
dancing with a sparkler blowing bubbles
we’re both adults it didn’t work out so
well to make a bubble machine that had
flammable bubbles but just blowing gas
into the bubble soap worked out quite
nicely I really like that effect it’s
something that I think I would like to
revisit maybe trying to make bigger
bubbles with more gaseous fireball
flames in them or maybe just using some
cooler footage of doing this same thing
both of those would be really neat what
would you like to see us try guys that’s
not all there’s still more for you to
