Super soaker flame thrower Answered

I know that if u put gasoline or alcohal in a super soaker, and attach a lighter to the front u can use it as a flame thrower, i heard u need a metal nosel through

Dose any one have any pics or any thing of how do do this?

PLEASE USE CAUTION WHEN PLAYING WITH FIRE THIS CAN EASLY CASUE DEATH TO USER

It won't explode because there is not enough oxygen in the tank to burn. There has to be the correct air:fuel ratio for there to be ignition, which is why the gas itself doesn't burn, the fumes do. There has to be more oxygen than there is able to be able to burn when it is in a liquid form.

I have attempted something like this before. I used a spray bottle filled with a 20/80 alchol/lighter fluid (naptha) mix. It is essential that you get a good spray, right between a mist and a stream to provide the right size of droplet for your fuel (just experimeent and find out). The alchol, which is quick to vaporize and has a low flash point, acts as an accelerator for the naptha, which is a petroleum distillate and relativly non-corrosive. The naptha is the main fuel and way not ignite until it lands on something (things totallyburst into flames if you do it right). The major problem is that after several hours of use, the alchol begins to mess up the spray mechanism on the bottle. Instead of using a Super-Soaker or other pressurized water gun, try using a regular pump/trigger model. Check out Tetranitrate's instructable on fire breathing to giv you a good idea on this sort of thing.

So whats different between a super soaker and a plastic gas can?

i think its the chemical make up gas can designd to hold gass and not leak a super soaker tank is made cheeply and only needs to hold water i think thats the only differance but im not sure.

Common plastics and their uses

Polyethylene (PE)
- Wide range of inexpensive uses including supermarket bags, plastic bottles.
Polypropylene (PP)
-Food containers, appliances, car fenders (bumpers).
Polystyrene (PS)
- Packaging foam, food containers, disposable cups, plates, cutlery, CD and cassette boxes.
High impact polystyrene (HIPS)
-fridge liners, food packaging, vending cups.
Acrylonitrile butadiene styrene (ABS)
-Electronic equipment cases (e.g., computer monitors, printers, keyboards).
Poly(ethylene terephthalate) (PET)
-carbonated drinks bottles, jars, plastic film, micro-wavable packaging.
Polyester (PES)
-Fibers, textiles.
Polyamides (PA) (Nylons)
-Fibers, toothbrush bristles, fishing line, under-the-hood car engine mouldings.
Poly(vinyl chloride) (PVC)
-Plumbing pipes and guttering, shower curtains, window frames,flooring,erotic clothing.
Polyurethanes (PU)
-cushioning foams, thermal insulation foams, surface coatings, printing rollers. (Currently 6th or 7th most commonly used plastic material, for instance the most commonly used plastic found in cars).
Polycarbonate (PC)
-Compact discs, eyeglasses, riot shields, security windows.
Poly(vinylidene chloride) (PVDC) (Saran)
- Food packaging.
Bayblend (PC/ABS)
-a blend of PC and ABS that creates a stronger plastic. :Car Interior and exterior parts

Special-purpose plastics

Poly(methyl methacrylate) (PMMA)
-contact lenses, glazing (best known in this form by its various trade names around the world, e.g "Perspex", "Oroglas", "Plexiglas"), fluorescent light diffusers, rear light covers for vehicles.
Polytetrafluoroethylene (PTFE) (trade name Teflon)
-Heat-resistant, low-friction coatings, used in things like "non-stick" surfaces for frying pans, plumber's tape and water slides.
Polyetheretherketone (PEEK) (Polyketone)
-Strong, chemical- and heat-resistant thermoplastic, biocompatibility allows for use in medical implant applications, aerospace mouldings. One of the most expensive commercial polymers.
Polyetherimide (PEI) (Ultem)
- A General Electric product, similar to PEEK.
Phenolics (PF) or (phenol formaldehydes)
-high modulus, relatively heat resistant, and excellent fire resistant polymer. Used for insulating parts in electrical fixtures, paper laminated products (e.g. "Formica"), thermally insulation foams. It is a thermosetting plastic, with the familar trade name "Bakelite", that can be moulded by heat and pressure when mixed with a filler-like wood flour or can be cast in its unfilled liquid form or cast as foam, e.g. "Oasis". Problems include the probability of mouldings naturally being dark colurs (red, green, brown), and as thermoset difficult to recycle.
Urea formaldehyde (UF), one of the aminoplasts and used as multi-colorable alternative to Phenolics. Used as a wood adhesive (for plywood, chipboard, hardboard) and electrical switch housings.
Melamine formaldehyde (MF), one of the aminoplasts, and used a multi-colorable alternative to phenolics, for instance in mouldings (e.g. break-resistance alternatives to ceramic cups, plates and bowls for children) and the decorated top surface layer of the paper laminates (e.g. "Formica").
Polylactic acid
-a biodegradable, thermoplastic, found converted into a variety of aliphatic polyesters derived from lactic acid which in turn can be made by fermentation of various agricultural products such as corn starch, once made from diary products.
Plastarch Material
-biodegradable and heat resistant, thermoplastic composed of modified corn starch.

which is why you have to know what you are dealing with.

So this would be a realy bad idea to try... maybe i could rig a servo up to it so i just pump it up walk away push the button and watch it shoot fire then exsplode or w.e happens when its outa presser-gass-working parts.

mabe a thick ziplock bag with the little tube that normaly sucks up water leading into the bag or a similar system...

if a super soaker had a water pump, this would make it safer-but not by much. get away from the idea that pre-made plastic items are going to be safe. at best, you need an auto store or junkyard for gas-safe plastics. remember-if you can get wet using it, you might as well be dead.

A) The plastic you are looking for is called "HDPE" (plastic gas cans)
B) Super-Soakers are commonly made from "PETE" and "LDPE".
C) Neither are particularly vulnerable to gasoline as they are to acetone.
D) Flame cannot possibly even get sucked into a nozzle that small.
E) Learn your plastics: http://tinyurl.com/2ctgfu
F) Making a watergun shoot flammables is never safe anyway, so don't even try it unless you are going for the Darwin Award!

Here you go.
I happened to find this link while searching for an explanation for why flamethrowers don't explode. Is this because it automatically shoots the fuel in streams so the flame doesn't go into the fuel container? Or the fuel shoots out so fast the flame doesn't have enough time to reach the end.

None of the above. There is not only a flame-screen at the end of the tube, but also the valve itself aslo prevents flame from traveling through it. Remeber that gasoline does not burn. There is no way to make gasoline burn within the reaches of human technology. Gas FUMES burn. Those who know what "quech-threshold" is know why flamethrowers don't explode, and it has absoluteny nothing to do with how fast it comes out, since once you stop, you have stopped the flow but not the combustion...

Even "real" flamethrowers are unpopular with their users, due to the risk of burn-back and blow-back (where the wind brings the flame right back at you).

Flame-throwers don't explode because they pump fuel out faster than the flame burns back along the stream. The fuel tanks need to be pressurised, which is why Supersoakers are so tempting to turn into flamethrowers. Unfortunately, most easily-obtainable fuels will dissolve the plastic of the gun (plastic dissolved in petrol = napalm), and the pressure drops off so quickly when you fire that the flame can easily burn back towards the gun.

Consider this: your supersoaker is slung from your shoulder, tucked under your arm. When it eventually explodes into a ball of fire an napalm, you won't be able to drop it, and it will be burning through major arteries.

Enjoy yourself.

"you won't be able to drop it, and it will be burning through major arteries." Lol I'm not trying this. Maybe if I set it up so the trigger could be pulled remotely, but I definitely wouldn't hold it myself.

yes, just add gasoline to a Super Soaker™ and incorporate a metal nozzle to it and you will have a basic hand-pump flame thrower. To add, this is a Darwin-award-winner if you dare to try it, as this can explode if done without proper pyrotechnics experience.....I would not recommmend it as it can be dangerous for the non-stunt-trained.....

Yeah, like if it floods or something and then goes BOOM!

If the stream that it lets out is constant enough...it will explode. So the tip has to be made right so that the drops of gasoline aren't one stream.

try again? the edge of the liquid is what vaporizes and burns.

If theres a mist, all the droplets are apart and wont feed back into the tank to explode. If its a steady stream, it will. Its this same concept that doesnt make you get electrocuted if you pee on the third rail of a subway. It's also why fire breathers have to get their blowing into the perfect mist before they actually use fire and flammable liquid.

ok, um, that's two very different things. electricity is conducted by touch-a broken stream of droplets won't conduct (but may be close enough to reduce resistance enough that sparks can bridge, so don't test your theory. accidentaly peeing on an electric fence is one thing, third rail is in a different class). fire needs air (or at least an oxidizer). fire breathers need to have a mist to maximize the surface area so that all the fluid burns quickly. if they don't exhale fast enough, the flame travels back into their mouth (flame propagation rate-basicaly how fast something burns). in this case, IF your supersoaker doesn't explode (gas softens many plastics) or dribble all over your shoes, the last shot is going to be air with a significant amount of gas vapor-an explosive mix that will travel into the tanks and explode. to try to say it a different way, a glass full of gas will burn only at the surface-pritty, smoky, hot, but not to dangerous. a room filled with gas vapor will explode as all the molicules and droplets burst into flame at (nearly) the same time.

more like a self immolation device. it might squirt burning gas, it might leak gas all over you, it might fail under pressure covering you with gas while you are holding a flame, it might just have the nearly empty tanks explode near your face. there's what, 4 or more types of plastic in a super soaker that could fail (tanks, seals, valve/trigger group, tubing, nozzle...), the joints could leak, plus things like filling and emptying it (under pressure or not), spills, bad gust of wind, splash effects... you can make a safe flamethrower, but not out of a water toy.

think plastic think solvent think pressurized container think flammible think open flame think Darwin Award Winner make sure to have someone on hand taking pictures. be sure it's a good friend, one that won't run for the phone, or freak out and drop the camera. better make it a tripod instead of a friend. web camera preferably. yes, i've seen how someone did it. they thought about it first.
