Introduction: Making Magic Flaming Bubbles...

Ever felt the need to burn bubbles? Found it wasn't as satisfying as it could be?

Now when you burn bubbles, they burn you...

Please note that the metacafe usage is likely short term, I'm not mad keen on them but I'm sick of youtube's insane compression amounts and Revver are still reviewing, metacafe come fast...

Step 1: Things You'll Need.

Picture of Things You'll Need.

Very little in reality...

- A glue gun or some such, any glue that'll stand up to water.
- A pencil/screwdriver, something to poke a hole in the container...

- A can, I suggest a fizzy drink can since they're thin, a red bull or tall can would be good.
- A lighter reservoir, nothing as fancy as the one here needed, that was the first I found
- A few little bits to attach the two together
- Some shower gel or washing up liquid (I used shower gel since the washing up liquid was downstairs, fairy liquid is one of the best things for this little project)

Step 2: Attaching It Together.

Picture of Attaching It Together.

This is relatively simple, poke a hole in the can, make it slightly smaller than the injector nozzle.

For putting it in I used part of a jet lighter nozzle (the bit that the tubing attaches to) screwed in to an adapter from a swan lighter refill can.

Slowly push the nozzle like object in to the hole while twisting it round, this will make a nice hole that fits quite tightly.

Fire up the glue gun or whip out your glue...

Put the nozzle about half way in to the hole and run a bead of glue around it then push it all the way in, gently.

Allow the glue to cool or dry and continue.

Step 3: Fill 'er Up.

Picture of Fill 'er Up.

First attach all the parts together, so the water doesn't flow back out the nozzle bit, I forgot to do this and it made things a little awkward and a tad messy.

Drop in a little shower gel or other soapy liquid.

Now slowly fill with water, if it doesn't foam up at all then add a bit more soap, we're not trying to foam it up loads but we want to know it will foam up.

Step 4: Bubbling of Doom.

Start adding gas to the can, just keep it flowing until the bubbles have reached a desirable size, I'd suggest watching the video first, a small amount of bubbles can have quite a considerable flame burst...

If I had a higher ceiling I'd possibly let it go for longer.

Soon you'll see a bigger one that auto ignites the bubbles periodically...

I actually got this idea from the way you spray butane in to a cup to make flaming water, I wondered about bubbles and discovered that Mythbusters had already done it when I showed my little brother... What's more worrying is I haven't seen that episode...

you could also do it by splitting h2o instead of wasting gas

MrPyro1010 (author)omkar_hummer2009-07-21

ya but then you have to go through making the whole setup .... it's easier just to use toilet cleaner and tinfoil, put a balloon over top and you get the hindenburg. (anarchists cookbook reference) :D

ilpug (author)MrPyro10102011-03-09

That is a felony in most states, don't do it.

Kiteman (author)2008-07-17

Sweet. I do this occasionally with mains-gas methane and a washing-up bowl full of suds - bubble in the gas (from a bunsen tap on the lab bench), make a big mound of bubbles, throw in a match. It gives a very satisfying column of fire.

killerjackalope (author)Kiteman2008-07-17

Aye, I'm tempted to use the outdoor gas line we have in the garden I have a hose for it somewhere, natural gas is pretty light, I could probably get floating cloud of bubbles, flick matches at them...

Kiteman (author)killerjackalope2008-07-17

Oh! I think that was in a Mythbuster episode - they filled a dustbin with soapy water, bubbled gas through it to make a bubble tower, several feet tall, and then lit it. They were trying to prove something, but I forget what.

Kiteman (author)Kiteman2008-07-17


I just thought - if you fed air in at the bottom, with the gas, and lit the mixed bubbles, there's be a much more satisfying flame, possibly a bang.

killerjackalope (author)Kiteman2008-07-17

I was thinking about using an oxy acetylene torch then using a flaming arrow from a crossbow to light it, I imagine the detonation of bubbles would be in the unholy class...

I will give it a go, I have a decent venturi for a torch here, If I use less water I should be able to make it work...

Kiteman (author)killerjackalope2008-07-17


killerjackalope (author)Kiteman2008-07-17

initial tests show air plus gas mix is a bit scarier...

How about a much bigger one with toilet....

hmmmmm i see java injection in the near future ............ time for some pentesting :D

Damnit, I hate metacafe... It works... And I love revver it lets you have a logo and lots of toys...

killerjackalope (author)Kiteman2008-07-17

It's actually not great, it made a much smaller burst of yellowish burning flames, similar to when a boiling pot of water drips in to the flames on a gas oven... I suspect the mix wasn't good though, it's not easy to keep the venturi from backing up... I'll get a few straws or something...

killerjackalope (author)Kiteman2008-07-17

Will do, I'll drop by the mechanics as well, they let me weld once or twice, maybe they'll let me blow them up...

pyro PJ (author)killerjackalope2009-06-12

Do be careful... A friend of mine filled a garbage bag with acetylene and lit it with a very long visco fuse...and it blew out three windows in his barn. But it was IMPRESSIVE!

firemanfu (author)Kiteman2008-07-18

the mythbusters used methane i think

i thought it was propane...

propane sinks.

ya know, i didnt really think about that! so much for taking chemistry. it really helped lol.

im pretty sure it was methane, i don't know for sure though

now tha ti think about it, i think you are right

where do you get a lighter reservoir?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!!?!?!?!

A lighter, refillable... Not something like a clipper though simply because they go directly to the valve and you cant separate and attach the pipe easily. The one in the picture came from a random jet lighter, the pipe is common to most lighters, the nozzle is from another jet lighter...

Actually, you can get a reservoir with a tube and everything from a long stem, barbecue lighter. It also comes with a tiny piezoelectric sparker!

softairdude (author)technodude922009-07-06

I use those for everything. They also make great mini potato guns. think about that.

mettaurlover (author)2009-02-19

are you insane? you can't have an instructable like this without teaching us how to make it make a fireball :(

You just keep making bubbles and touch a lighter to it...

yep. that's about how you do that. even more fun is putting a little fan behind the can, holding the lighter in front of the can, and shooting fireballs at stuff!

craniumofuranium (author)2008-09-17

My physics teacher is so cool, he uses mains gas and washing up liquid, the he picks up the bubbles and gets someone to light it in his hands.

that is awsome!

how do you make it bubble?

Turn on the gas after putting soapy water in...

Xander da gr8 (author)2008-07-20

does it have to be a lighter? All you neeed is something with a small flame.

Umm I realized you could just shove a disposable in to the side of a can and hot glue around it, then push the valve...

GorillazMiko (author)2008-07-18

I like it. +5/5 stars.

Thanks GM....

pyro13 (author)2008-07-16

What kind of lighter is that you used to light the bubbles? it looks neat!

killerjackalope (author)pyro132008-07-17

It's an old Dunhill Rollalite.

pyro13 (author)killerjackalope2008-07-17

Alright thanks! Good quality?

killerjackalope (author)pyro132008-07-17

Yeah lovely, that one's made out of silver, I have a pewter one some where, along with that a gold plated varaflame which is very similar but is made by ronson, it's nice aswell though a later one with gas instead...

pyro13 (author)killerjackalope2008-07-17

I looked around, and i could only seem to find antique ones? where could i find a newer cheaper one?

killerjackalope (author)pyro132008-07-17

Not very hopeful, have a look in a few antique shops for ones going cheap maybe a high quality tobacconists... The new one's mightn't be any cheaper.... If you have no luck at all you could buy a broken one and fix it, petrol lighters are very simple or even send it to me and I'd do the fixing...

pyro13 (author)killerjackalope2008-07-18

Ok, thank you for the help =D

killerjackalope (author)pyro132008-07-18

I fyou do find a bust one on the cheap PM me with the problems, I can always walk you through fixing them...

Spectrace (author)2008-07-16

That Mythbusters episode was just on last week. i think it was tuesday or wednesday. I waswitha friend at his beach house and watched it. I think they use nitrogen or hydrogen for the gas though. Or helium. i forget which
