thanks for sharing! My thought has always been: even if the bottle was perfect and didn't fail, its design is to insulate which is the exact opposite of what you need when trying to boil water.
If the bottle was punctured then the myth thinks that the vacuum on the inside would suck a bunch of air towards the inside and cause an influx of oxygen to reach a flame. It still makes 0 sense because a flame won’t likely puncture a fast hole and cause an influx (hence no popping sound in the vid) and the vacuum would suck air away from the fire, not towards it. Myth busted lol.
People claiming that it would explode doesn't really make sense. If there's actually a vacuum inside the bottle, then there's no air to expand when the bottle heats up and therefore no pressure to blow the bottle apart. On the other hand, if the bottle had a leak in it and undid the vacuum property, then any heated expanding air could also escape through that leak. So either way people's claim of vacuum bottles exploding doesn't make any sense.
I think the advice not to use insulated bottles is because of materials that used to be used. I'm pretty sure old thermos bottles used to use a layer of glass. Glass will definitely break if it has a rapid temperature change and sometimes it can be fairly violent. I don't know for sure but I think that is where the advice comes from.
I had never heard of it or even thought of putting my vacuum bottles in a fire. Two out of three of mine have plastic parts, so no. Ron Hood recommended a coffee can with a bail attached. Now even cans are hard to come by. Just carry a can or a cook pot. You can pack other stuff inside it. I wear goggles if I break the teat off an old TV picture tube, in case any glass flies when I break it. It won't explode, air rushes to get inside it when you break it. Edward Abbey had worked out how long he could leave a can of beans in the fire without blowing up the can, and still get the beans hot. Maybe you can play with that one! I forget if that was in Desert Solitaire, or another of his books. The inside layer of old Thermos bottles was glass, later plastic. Kids at school liked to see if they could make you drop your lunch box, and thereby break your thermos bottle.
Its a vacuum insulated bottle. There is a vacuum in between the inner and outer wall not pressurised gas so when the bottle is heated there is no buildup in pressure because the whole point of being vacuum insulated is that there is virtually no air between the inner and outer wall.
I'm trying to make a hole in my insulated water bottle, I was wondering if it would explode or anything. I'm thinking what would happen is just the air coming in the vacuum chamber really fast. has anyone done this?
First of all I took out insulating shell from my plastic bottle and washed my bottle and kept plastic shell at one side and insulating shell at one side! After few minutes insulating Shell blasted and all glass and mirror shattered!! What was reason ??? I am scared 🙏🙏🙏🙏
@@Equip2Endure If you want to help, get your buddies to road march their bug out bags 20 miles and sleep in the dead of winter with whats in their bag... see what happens. How many won't make it because they are too fat, packed too much nonsense in their bag or didn't bring the right gear?
Surprised by the result?

You're thinking about it exactly right, thenextarcher! Thanks for watching. -Rusty
If its vacuum insulated, then there is no air to heat and build pressure. Not sure why people think it'll explode.
It's an old tale that people in the survival community tell each other but don't really test apparently. Thanks for chiming in, Rmartin689! -Rusty
Exactly what I was going to print!😂

I thought the reason was the timing. You proved it... I never thought about it popping! Thx!
You bet, Dave! Thanks for watching. We were curious ourselves. Now we know. -Rusty

Honest question, there have been news and videos of vacuum bottles exploding, what actually caused it then?

That could very well be it, Jeff King! Thanks for watching. -Rusty
I wonder if it became unsealed or unvacuumed so the water did boil. So maybe re test the same bottle and see if the boil time has changed
I also wonder what happens with a ferro rod if it fells in the camp fire...
Hey guys glad to see this channel back making videos... may I ask what happened to adam? Keep up the great work 👍
We provide a video explanation in a Facebook Video posted several weeks back. -Rusty

Thanks for chiming in, Daniel! There are definitely lots of options our there. Thought we would put this old opinion to the test. -Rusty

Thanks for this. I've been wondering!
You bet. Thanks for watching, C j! -Rusty
Some of them have a solder plug maybe you melted it. For it to explode you need to have the lid on it and boil it then it will definitely explode.

Hope it was helpful. Thanks for watching, concrete cowboy! -Rusty
The time to achieve a boil is nuts. I wasn’t expecting that.
Was definitely an interesting experiment. We did it so you didn't have to! Thanks for watching, Mark. -Rusty
That time isn't that surprising I don't think, given it's a pretty weak fire and it's a tall bottle. It's not a camp stove after all
I was never a hippie either! Lol
IT WONT EXPLODE IF ITS NOT SEALED.
Minutes afterwards BOOM
Nope. But we should have thrown a soda can in there to at least get some satisfaction, right? -Rusty
Vacuums don't explode, its not recommended because of the poor transmission of heat.
Thanks for watching, 3vil3lvis. We did it so other people wouldn't have to waste their money and they could see what happens. -Rusty

@@3vil3lvis That is sound advice that we have considered. May do a video on something like that. -Rusty
Try letting the water boil out and leave it
If it has water inside after the test it would probably explode the next time you use it.
Should we try it? 😆 Thanks for watching, jchiliw! -Rusty
Anti-climactic, but informative. Thank you for braving the potential.
You got it, DP. Thanks for watching and glad you got some use out of it. At least it got us out in the woods, right? -Rusty
@@Equip2Endure A bad day in the woods, is still a good day!

What you're hearing is probably the foam liner having melted and contracted into a small mass at the bottom of the space between the double walls.
