Introduction: Pyro Glove/ Wrist Mounted Flamethrower

Picture of Pyro Glove/ Wrist Mounted Flamethrower

For this instructable I am going to teach you how to make a Pyro glove/wrist mounted flamethrower. It is very simple and super fun to use. I got the idea to make this from Pyro/John from X-men the last stand. I this will not make it possible for you to manipulate fire it just throw it. Warning this instructable deals with high voltage electricity and fire, and I can't be held responsible for any destroyed property or if you hurt yourself or anyone else in the process of making or using to device. So now that we got that take care of let's get started.

Step 1: What You Need...

1. Butane refills (I used 18 ml. canisters)

2. Fuel line

3. A glove

4. Some thick string

5. A straight metal bracket

6. Some stiff wire

7. Something that can hold the butane canister (I used an old pocket knife holster)

8. A small piece of tube.

9. A metal nut (like a nut and bolt not like a peanut) it needs to be big enough that the piece of tube can fit inside the hole.

10. Some cardboard(you can use a wrist brace in place of the glove and cardboard).

11. A few bracelets or some thin rope

The next few things are optional you only need them if you want to make the igniting mechanism (I would suggest that you just use a Bic lighter because the igniting mechanism doesn't work well)

12. An electric flyswatter

13. Some electrical wire

14. A wire connector

Step 2: Tools...

1. Hot Glue Sticks/Hot Glue Gun

2.Solder/Soldering Iron (Optional)

3. Multi Tool

4. Drill

Step 3: The Glove.....

Picture of The Glove.....

The first thing you need to do it get your glove. You are going to want to cut a hole in the center of your palm (Tip: I always burn the edges when I make a cut in the glove.). Now, set the glove aside and take your fuel line, the small piece of tube, and the metal nut. Take the plastic tube and use hot glue to close off the one end. Now drill a hole in the side of the small tube just big enough for the fuel line to fit in. Stick the tip of the fuel line into the hole that we just drilled and use hot glue to hold it in place. Now, take you metal nut and glue it on the open end of the plastic tube. Now, put all the stuff that you just glued together into the glove and push the nut through the hole you cut in the palm. When you look at the glove, all you should see is the nut sticking through. (Optional: You can use a needle and thread to hold it firmly in place.) Put hot glue around the nut on the outside of the glove to prevent the nut from falling over in mid use. Now, set the glove aside.

Step 4: The Butane Canister Holder...

In this step you will need to cut piece of cardboard the appropriate size for your forearm. We are going to be using the cardboard to mount the Butane canister on your arm. In this step, you may have to improvise with the materials. I used an old pocket knife holster. But, you can use zip-ties or anything you have lying around that will hold the Butane canister tightly in place. If you are using zip-ties, you will want to cut slits on one side for the straps to go through. (Refer to pictures for more details.)

Step 5: The Butane Releasing Device...

For this step you will need the stiff wire, thick string, and the straight metal bracket. Use the stiff wire to make two loops that can fit loosely over your fingers. Now take the straight metal bracket and drill a hole in the center of the bracket just big enough to fit the tip of the nozzle of the Butane canister. Then drill two more holes on the straight metal bracket on each side. Those holes just have to be big enough to put the thick string through it. Take your thick string and cut two pieces the length of your finger tips to your elbow. Tie one to one of the stiff wire loops you made and tie the other string to the second loop. Take the cardboard with the butane canister in its holder and stick the straight metal bracket over the nozzle with the hole you made earlier. Then, secure it firmly on your arm at the appropriate place. Then, take the two loops with the string tied to them and place them over your middle and index fingers. Put the stings firmly down to the straight metal bracket that is placed over the butane canister and tie them tightly in the hole that you made on the sides. It is important the you have your hand flat while measuring this distance.

Step 6: The Igniting Device (the Optional Step) ...

Picture of The Igniting Device (the Optional Step) ...

This step deals with high voltage electricity so be careful!!! This stepis optional, in place of the igniting device you can use a lighter it is much smaller and easier to use. But just in case you want to make it here are the instructions. The first thing you need to do is pull out the batteries (if you are using rechargeable one and you can't pull the batteries then just be extra careful because you can give yourself a nasty shock) You need to do is take the electric fly swatter, unscrew all of the exterior screws. When all of the screws are out pull off the outer plastic casing (be really careful what you touch to make sure you don't shock yourself). When the plastic casing is off the part that zaps the bugs should be connected to the circuit board by three wires, cut the wires in such a way that there is as much wire left attached to the circuit board as possible. Two of the wires attached to the circuit board lead to the same solder point cut off ONE of them. Now solder the remaining two wires to the two leads of the female piece of the wire connector(you don't need to use a wire connector but it makes it easier to put on and take off). Now take the stiff wire bend them into two L shapes. Now take the L shaped wires and glue them to the side of the nut that is attached to the glove (make sure the wires don't touch the nut). Make sure the ends of the L shaped wires that you glued to the nut almost touch in the center of the nut (right over the hole) so the spark will jump across the gap and ignite the butane gas. Now take about three inches of electrical wire and strip both ends of both of the three inch wires. Now take one of the wires we just striped and solder one end to one of the L shaped wires and the other end to one of the leads the other piece of the mail piece of the wire connector. Now take the other piece of three inch wire and solder one end of it to the other L shaped wire and the other end to the other lead of the male wire connector. And your done!!!

Step 7:

All you need to do to use it is put it on, put everything together bend your wrist back to release the butane and ignite it with a lighter or with the igniting device by pressing the button on the handle. The farther back you bend your wrist the bigger the flame. Have fun and be very careful!!! Your votes would be very much appreciated!!!

nice project it will work oneday fo ma protection lol thanks for sharing

Himers (author)King Cyber 2016-01-29

I'm glad you like it!!!

YourLightbearer (author)2016-01-10

Where did you find/get the fuel tube/line thingee?

Himers (author)YourLightbearer2016-01-10

You can buy it online or you might even have something laying around the house.

YourLightbearer (author)Himers2016-01-11

Ok, thanks!

itsthatsguy (author)2014-11-09

I do like the idea, and i theorized building a device like this once, I asume it could be done safely, but id use some kind of kiln or crucible style gloves for the glove you mount it on, there flameproof and withstanding massive temperatures without burning your skin. Furthermore no tubing exists that is both butane safe and see through, in your instructable you mention fuel line, which is also wrong as gas, diesel, and alcohol will not dissolve what butane can. it looks like you using vinyl which will dissolve until it ruptures and expends butane. There are basically 3 types of rubber that are butane safe, BUNA-N (nitrile or NBR), Viton (FKM), and extruded ptfe (which requires a steel braid to operate over 20 psi), Please do some chemical compatibility research and design your ideas to be safe before releasing a guide on how to build these. Your asking for permeant burns on about 20-30% of your body from that canister, Butane is a hell of a flammable gas, and just as importantly a solvent.

If you think im wrong then feel free to goto: and look for yourself, Cole parmer is a lab supply company whose nie enough to supply us with a neat little chart allowing you to check any material vs any solvent, its an excellent resource.

Barbeque lighters use a clear, vinyl-like (if not just straight vinyl) for the deliverance of butane to the ignition point. Might wanna check your facts again

Himers (author)itsthatsguy2014-11-10

Itsthatsguy, I don't know how accurate your source is but I have seen many people on internet using this kind of fuel line and nothing has happened. And also I have been using this fuel line for weeks and I just went to check the fuel line and I see no signs of it dissolving. Now don't get me wrong I am not saying you are wrong... but maybe that is the case only if you are using it for long periods of time. Again I am not saying you are wrong and so for that reason I am going to pay close attention and if I see anything happening I will post something on my instructable telling my viewers to switch out the tube. Thanks for expressing your concerns!!!

a2e (author)Himers2014-11-11

Rad work!

I totally agree with you.
There are people that build, and there are people that complain. BTW: Where you shot the vids? It's a nice place and I'm happy that you didn't burn your eyebrows at the end, although it is not as serious as everybody claim, I've seen it go wrong and it takes a short while to get fine again.

Himers (author)a2e2014-11-12

Thanks!!! And you are exactly rite... this isn't as dangerous as people make it sound... It isn't like I'm playing with a "bomb"!!!

eruger (author)itsthatsguy2014-11-12

Me too. Have you priced a nomex trench coat lately though?

CrayfishYAY (author)2014-12-18

With this device, I will FINALLY be able to master FIREBENDING!!!!

r0b0t14 (author)CrayfishYAY2015-05-13

i know right!!

Himers (author)CrayfishYAY2014-12-21

Have fun!!! But seriously be careful.

CrayfishYAY (author)Himers2014-12-23

Oh, I haven't even made it, yet. I was just making an Avatar reference.

Himers (author)2014-11-09

Bcavaciuti, thank you for expressing your concerns, but you aren't taking everything into account. 1. The melting problem you brought up shouldn't be a problem because the butane is pressurized so when it is released it is freezing cold so it is cooling the nut and the fuel tube. 2. The outflow is controlled by me throttling it by me bending my wrist. 3. I did some research and something that I found is butane is preferred for this kind of thing because it WON"T burn down into the canister and blowup(also many or all of the lighters you own use butane so the same thing would be true for those lighters). 4. electrical flyswatter is not going to do any anything serious.... I got shocked several times by it and the most serious thing that happened was I got a small dot burn mark. 5. Now for the cardboard... I see what you are saying but cardboard is much easier to pull off than allot of things in case it were to catch on fire(Also I suggested in the video that you use a wrist brace in place of the card board and the glove). 6. Now all that is left is the glove point one when I gave the list of materials I didn't say what kind of glove to use in fact I again suggested that you use a wrist brace. Again thank you for expressing your concerns but this isn't as dangerous as you think(Obviously there is some danger involved in using this because it is a fire glove.

bcavaciuti (author)Himers2014-11-13

Thank you for replying but I am going off what almost every cheap generic glove is made out of acrylic with elastic...even if it is wool it still not that safe compared to leather. Also looking more closely at your arm brace you still have to remove the straps which are tied on the get it off, which in

Half the reason I commented is that I don't want you to get hurt and lose the ability to use your hands. Why not revise the instructible with better materials and safety measures because things like this are not worth taking large chances with...Just small ones else nothing is fun.

Himers (author)bcavaciuti2014-11-13

I am planning to revise my instructable in the future. Also I said cardboard would be easier to pull off in the case of an emergency because it isn't secured to the straps... the straps are just tied around it and they won't catch on fire as easily. So when you pull on it the cardboard would bend and slip through the straps.

bcavaciuti (author)Himers2014-11-14

But the straps will keep the butane canister trapped too your arm if it somehow does heat up or start spewing flaming butane everywhere then it will be pretty difficult to remove in a panic.

The reason I am so concerned is that my brother was making an action film with his friends once...So they decided to get a close up of an explosion to edit into it. They made a fire and placed a hairspray canister into it and sprayed another into the fire to heat it brother was filming less than a metre away and was engulfed in a fireball.

He sustained severe 2nd/3rd degree burns to his hand and lost his long hair. He was extremely lucky to have escaped with only that.

Luckily we had the pool up which he cooled it in soon after which along with a helpful neighbour and living relatively near to an amazing burns centre and living in England(free NHS healthcare :D) he has no adverse affects now. This was during his exams which meant he had to have a scribe and thus affected his results.

But it could have been so much worse. The doctors warned that he could loose all feeling in his hand and have to have skin grafts and horrible scars that would impare movement and be affected by sunburn severely for the rest of his life.

IT is not worth the risk for a small amount of fun when you can get the same fun without the risk.

Himers (author)bcavaciuti2014-11-14

You misunderstood me... the butane canister is mounted only to the cardboard(not to my arm)... the cardboard would be easy to pull off my arm if something were to go wrong.

treehog (author)2014-11-14

Be sure to post the video when you burn your house down.

Himers (author)treehog2014-11-14

I will tell you what I told someone else... if you are going to use or make you should be smart enough to use proper safety precautions!!! But thanks for expressing your concerns.

john henry (author)2014-11-12

I think it would be cool to make something like this but with far more safety involved.

sometimes being cheap isn't the best option.
I hope you will improve your design in the future.

Himers (author)john henry2014-11-12

Thanks for the suggestion!!! And I probably will make an improved design in the future.

Abhay Verma (author)2014-11-10

its good
I like'd it..

Himers (author)Abhay Verma2014-11-10

Thank you!!! Remember to vote!!! ;)

deadi (author)2014-11-10

It mighr work better if you used an arm like desighn intead of string. Like with thouse old spiderman web launcers. It would also be safer

Himers (author)deadi2014-11-10

Thanks for the tip!!!

nwlaurie (author)2014-11-10

One puff of wind in that last video and your hair would have caught fire. Which could blind you.

Remember: Dangerous chemicals and experimental bombs ('cos this IS a bomb) need SAFETY GOGGLES at the very least!!!!!!

Himers (author)nwlaurie2014-11-10

Yea!!! I realize how dangerous this can be. You just need to take the wind into account when you are using it.

TheAZAndyman (author)2014-11-09

I was hoping for the video. What about a welders glove a little more fire resistant than a glove that melts with fire.

Himers (author)TheAZAndyman2014-11-09

You didn't see the demonstration video in the last step. And also thanks for the tip!!!

TheAZAndyman (author)Himers2014-11-09

you are correct. I missed the file. I was looking for a embedded YouTube video,

Himers (author)TheAZAndyman2014-11-10

I am glad you found it!!! I know that it can be easy to miss.

Mooch07 (author)2014-11-09

Cool! pretty nice device there. Gotta watch that wind!

Himers (author)Mooch072014-11-09

Thanks Dude!!! And yea wind and fire are not a good combination.

woodNfish (author)2014-11-09

I was going to give you a high-five in this instructable, but I burned my hand off. Oh well....

Himers (author)woodNfish2014-11-09


LunaEros (author)2014-11-06

Can anyone else get the videos to play?

milesfromneihu (author)LunaEros2014-11-09

Played fine for me in Chrome Version 38.0.2125.111 m

oujo (author)LunaEros2014-11-09

The video played fine for me in 64 bit chrome 38.

Himers (author)LunaEros2014-11-06

I am not sure why the videos wont work... They are working fine for me.

Kiteman (author)LunaEros2014-11-06


@Himers, if you upload the videos to YouTube, then embed them, it makes life a lot easier for your readers.

burnerjack01 (author)2014-11-09

Could you please post a video of its use?

Himers (author)burnerjack012014-11-09

I already did post a video(in the last step).

deusprogrammer (author)2014-11-09

Can you post pictures from the burn ward once you are inevitably admitted after you soak the glove in butane and set your hand on fire? And then post it under "Step 8: This was a horrible idea".

Himers (author)deusprogrammer2014-11-09

Thanks for your concern, BUT I have done testing and I have had nothing of the sort happen. Also anyone that makes and uses one of these should know how dangerous it is and SHOULD use proper safety precautions. Again thanks for your concern and have a nice day!!!

chrslefty (author)2014-11-09

It would be way cooler if you had shown your glove in action.nice start and cool concept.

Himers (author)chrslefty2014-11-09

Thanks!!! Also I did make a video of the glove in action it is in the final step.

The Awesome Inventor (author)2014-11-08

Wow!! great instructable!!
