tin foil to use as pot to boil water

[malente]

Does it work?

I've yet to try it out.

I'm thinking that one could use copper wire to make a pot structure (weave or more primitive) and then cover it with tin foil (from the inside, so that the water would effectively hold it in place). It should be watertight and resistant to heat, no?

Would the copper melt or the tin foil warp (I think the aluminium melts at over 2000 degrees or something, so I would stick to smaller fires )?

Also, would there be any problems with the copper or tinfoil emitting nasty stuff into the water or would it be safe to drink afterwards?

I had a search but could find nothing. Cheers for any pointers or replies. Pics very welcome, I like to visualise things

I tried it once with general household tin foil, the first burn went okay but after that the foil became very fragile and broke up when I refilled it. I only tried it with two layers but maybe multile layers would work better.

I'd be interested to hear how you get on

I think the foil (aluminium) gets fragile because it oxidises.

I also think two layers may not work any better. There will inevitably be an air gap between the layers, which will insulate the outer layer from the cooling influence of the water, allowing it to reach melting point temperatures.

Chinese take away type tubs from Asda work ok. I use them filled with beer or water in my kettle barbecue & that gets really hot, One lasts me ages
They fold up & are very light too.

Calculon - I've got to ask....

Do I understand that you're heating beer? Does that make it better? (I'd love to know if I'm missing some sophisticated cocktail)

Hi PB, We use it to flavour the meat & keep it moist, some people use cider, wine or even whisky mixed with water. Keep the tray in the cooler area of the BBQ & close the lid.

OR - soft drinks such as Coca Cola are used as a quick marinade in some African countries, ideal for overnight soaking prior to cooking

Thanks, guys - I didn't really get it! Apologies for wandering off-topic..

[malente]

Great info, didn't know that either. Gotta try that... So no prob potboiler.

So what are alternatives, given that tin foil is no good for boiling water?

[Bushwhacker]

You can boil water in a plastice drinks bottle.
It has to filled right to brim with the cap on tightly so there's no air space.

I'm just not too sure if any chemicals from the plastic get into the water though.

Tin foil works but your are looking at a one shot item.......

The question is, having boiled your water, what are you going to do with it, make tea? then why not just use a metal mug and boil the water in that?

Hi Smoggy.

It's a survival type question. For normal camping/ bushcrafting use, I have my titanium pot & mug anyway.

In list for PSKs (Personal Survival Kits) there's sometimes tin foil included, and I try to ascertain the different uses.

One potential use is to use it to make a pot. Here, it would just make the water safer to drink or food stuffs like insects or fish or meat safer to eat (kill pathogens). I guess that's why many PSKs come in tins (like tobacco tins) that can be used to boil/ cook. I might scrap the tin foil then. Though I could still make a tin foil hat

Does this not result in the bottle rupturing when it does eventually boil?

Good old Bear Grylls was doing this on the telly the other night! He had the bottle suspended over the fire and kept it swinging gently so it didn't get the direct heat and it seemed to be OK. He did mention the noxious chemicals bit, but suggested this was true 'survival' technique and not the sort of thing one would normally do. I must say it's not the sort of thing I'd fancy doing...

[Minotaur]

Thing to watch is make sure you get aluminium foil.

Just because they call it that does not make it so.

One of the big problems we had trying to cook a fish once was the foil, only two of us attually had metal foil.

[8thsinner]

I have not tried this, but heres another suggestion.
Somewhere online there is a place selling extremely thin sheets of titanium for the initial use of cooker making, if these are thin enough to fold and you buy something large enough, I don't see why you cant keep a roll of it and fold in like a birch bark pot, pin it with pegs,and create a very solid pot with more than a one time use.

For something more space saving, some places now are selling the special crush able rubber bowls which can be used to boil water right on over the coals.

[malente]

nice suggestion, thanks! will look out for it.

[dwardo]

I would imagine hot rocks placed into a makeshift foil container should work. I have also heard about boiling water in a plastic bottle and i can imagine Bear doing it but i personally wouldnt want to risk it blowing up.

[sandbender]

I think that being aware that one 'can' use tin foil to boil water is useful info. However if a person is going to put together a survival kit and carry one around then a proper can is such a useful and multipurpose item that it would be daft to rely on tin foil to do the job.

An old coffee tin or baby food can makes a good container for your 'kit' and will be a godsend if you find yourself lost in the wilderness for a bit.

[malente]

Cheers sandbender, I agree. I'm gonna see if I can find a suitable container...

I'll post an update when I get round to taking pictures.

MMMMMmmmmm. Hot beer!

I can help on that one; had it quite a few times in Poland. Fantastic in the mountains in winter and most bars seem to do it. Big favourite with the ladies as well.

Take the beer of choice Tyskie, Zywiec, Lech (pretty good with Stella or Kronenburg)

2 x 500ml cans or as you want into a sausepan, a few cloves (8 maybe), and slowly heat up, stirring regularly.

Once nice and hot, pour into glass of your choice. There's a cordial mixer out there (you can find it here) called 'Mallina' (Raspberry flavour, like you can get concentated orange squash over here) A dash of that so it changes colour. DONE!

Trial and error will get you your favourite taste, and bladdered.

Happy days.....Na zdrowia!

PS I wouldn't try it with Debowe Mocna.

Shall we try that at Swift Valley???

Ah ha, then you're actually asking a different question......

Given that it may well have a number of potential uses in a survival kit then maybe you should keep it, but yes you can boil water in it.......or use it as a signalling reflector, or use it together with a piece of chocolate to polish the bottom of a beverage can to make a concaved mirror for signaling or fire lighting, or use it as a scouring pad for those burn on nettle stalks, use it to collect pine resin for fire lighting, or just for keeping food clean or cooking with.......etc......

I find the BCB mess-tin useful as a small container, too small to use as a regular cooking pot though

This ebayer looks to be able to mail to Germany (Boops has no links to this commercial seller!):

Tin foil would not be a good thing to rely on to boil water more than once I'm sure.
Now the thick metal tin type containers foldable containers that come with some ready meals I would think are another matter. Though I've never personally used one, they do seem to regularly come in the PSK packs, so I guess they can be used multipal time.
JMO, but I will try it out sometime, it would be much lighter than a cooking pot.....

Also not sure about the copper wire (My guess it would melt), but welding rod would work very well, would not melt, and can be bent to shape fairly easy.

[brancho]

You can also use foil as a wind sheild when cooking in a pot as in wild conditions it can be difficult to get a pot to boil wrap some foil round and teh heat gets to the pot and it boils

[thebeatmeister]

If you can fill a paper container with water and boil it over a bunsen burner (remember your science lessons?) then i'm sure you can do it using tin foil??!!.....Truth is i've never tried it so i don't speak with the voice of experience BUT i do carry tin foil for many reasons; other than to signal and potentially wrap food i would consider using it to line a natural rock depression which then gets filled with water to be boiled by a super heated stone from a fire. That i HAVE done and it works. It all seems a little mute though because like a previous postee mentioned - i nearly always carry an aluminium non-stick '58 mug underneath one of my bokkles.....Failsafe......

Have a look at this web page, although it is specifically about US brands of foil

hmmm , I'm getting water to boil with heavy-duty US foil, no leaks. The thin stuff does leak(pinholes at wrinkles/creases) but my neatly folded, heavy-duty foil, square-pot has boiled a pint of water 3 times so far without leaking one drop. Now on boil #4 and it's starting to leak. Don't think I would trust a piece of foil that has been folded up and stored for this purpose though, don't think foil crudely shaped into a cup(many wrinkles) is going to work very well.
