Cooking With A Double Wall Titanium Mug | Will It Explode?!

[@shootermcmillan]

Well.....you managed to prove how effective at insulating a double wall mug is. It should be obvious that something intended for the opposite of cooking would not work out so well. Thankfully it was well made and did not explode.

[@BackcountryExposure]

shootermcmillan yeah I feel like the results aren't mind blowing by any means, but having never really seen real evidence of what happens, it was worth the time to see. Thanks for watching!

[@brianwest2775]

If there's a vacuum between the walls, then there's nothing to explode. If the metal was heated enough to lose it's strength, then it would collapse inwards like you see in the experiments of heating a metal jug or barrel and then rapidly cooling it. If there's air in the gap, then the air will heat and expand but the air pressure is probably small compared to the strength of the cup. It's possible that the bottom curved down because the air expanded and pushed out the weak bottom but I suspect that it's simply the metal expanding as it get very hot, so it has to bow up or down and gravity dictates down, plus already curved downwards at the edges.

[@greenspiraldragon]

It heated enough to bulge so something could happen. If there was a small amount of moisture inside the double wall it could actually explode.

[@justsayin899]

I probably wouldn't of done that on an above the cannister stove and a timber veranda but I'm glad that you did! Very cool experiment. Thanks.

[@gordonmurdoch3811]

Why would you want to try and boil water in a cup that is designed to insulate against heat transfer? Can we expect a future video on fire lighting with a fire extinguisher?

[@alex_8025]

To see if it would explode...

[@pozsmith8207]

Shit happens. What if you're in the woods and all you have is your double walled water bottle.

[@cascaderetriever7618]

Curiosity 😊

[@Chungustav]

Thanks for the visual demo! Most heat transfer occurs through the neck and opening of the flask, where there is no vacuum, so a different shape such as a bottle would react differently. Not surprised it took long for the water to boil as by definition: A vacuum flask (also known as a Dewar flask, Dewar bottle or thermos) is an insulating storage vessel that greatly lengthens the time over which its contents remain hotter or cooler than the flask's surroundings.

[@brianwest2775]

Probably not. Heat transfers by three possible modes: Conduction, Convection and Radiation. Double-wall cuts out the direct conduction. If there's a vacuum, it cuts out convection but it doesn't block radiation. I bet that the heat transfer from radiation far outweighs the heat transfer via conduction at the lip because heat transfer is directly proportional to the area. The lip has a very small cross-section whereas the rest of the cup has a much much larger area and the bottom of the cup is essentially at the temperature of the flame, so it's radiating a significant amount of heat. I don't think that you could maintain boiling with the heat transfer through the lip.

[@marshalraylangivens4996]

When I seen the bottom swelling out, I thought you was fixin to get a face full of titanium fragments. Glad it didn't blow on you.

[@BackcountryExposure]

ha ha. Yeah this could have gone wrong real fast. But worth the experiment.

[@danielholtz1066]

i was thinking the double wall would be good for baking muffins or biscuits now since its deformed. i like that someone tried this, thanks!

[@bloodseedrums]

Daniel holtz hmm mm you just got me thinking, (I just started into trail baking) I wonder how well the mug would withstand repetitive cycling

[@deniznarin]

Like the way you are thinking, people don't think differently,i was looking for this because i want a minimalist setup, thank you very much!

[@aspringjeo8075]

thanks testing! and i wanna buy a single wall mug to boiling water,so i want to know the mug can change the color?

[@TimWatsonOutdoors]

Lol, the best videos are the "what the heck would happen if...." 😂

[@BackcountryExposure]

Tim Watson bingo!

[@northcountryadventures7619]

cool experiment. I was recently looking at different cups/mugs and was wondering if you could or should cook with the ones with double walls. I didn't think you should and I believe that your test proved it's not the best idea. Thanks for sharing

[@BackcountryExposure]

North Country Adventures thanks for the watch!

[@jarikinnunen1718]

It have no gas in it to transfering heat. That is its big idea. If you go to Siperia and in -55 Cold and stand perfectly still, you not feel that cold because you have warm air next to skin but if you move yourself it gone.

[@jeromebullard6123]

I have that mug and love it. Keeps my coffee hot for a long time. I thought it was a vacuum inside but apparently not since obviously there was enough gas/air inside to expand and push the bottom out.

[@brianwest2775]

I'm not sure. it's possible that the bottom curved down because the air expanded and pushed out the weak bottom but I suspect that it's simply the metal expanding as it get very hot, so it has to bow up or down and gravity dictates down, plus already curved downwards at the edges.

[@OUTDOORS55]

I think the pressure pushed the bottom out. I would assume the rounded parts of the mug add strength and the flat spot is the weak point, but who knows lol. Im impressed by that stove. Thats definitely faster than the pocket rocket. Pretty cool👍

[@philiporlando616]

Pro trick: you can watch movies on Flixzone. Me and my gf have been using it for watching a lot of movies recently.

[@cairomitchell3552]

@Philip Orlando definitely, I've been using Flixzone} for since december myself :)

[@lennoxroger4151]

@Philip Orlando definitely, I've been using flixzone} for years myself =)

[@victorethan1041]

@Philip Orlando definitely, have been using flixzone} for months myself :)

[@MrDecennia]

Would there be a way to fix the bottom to get it flat again?

[@craftycamping5355]

Good video. Guess it does show that it's insulating properties work reasonably well.

[@defel1]

Performance--failure--depends on the quality of construction, I suppose. And I would guess the distortion of the bottom had something to do with the expansion of the air between the walls. I wonder what the manufacturer says about the effects of cooking with their product.

[@72daystar]

But does it blend?

[@polsonowal07]

Can I cook small pieces of chicken pieces in any camping titanium mug or pot ?

[@jamesreck8476]

drill a pinhole into the outer layer before heating...

[@RESTLESSOUTDOORS]

6 minutes to boil... wow! Amazing how well the double walled is insulated! Sucks about the warping but all in the name of science! Great video!

[@rootvalley2]

there should be a vacuum in between the two layers for insulation, heating it will not heat the inside.

[@guns4funcajanajustin]

Very cool experiment Devin!

[@BackcountryExposure]

Thanks Justin! I wasn't sure what would happen, but cool either way.

[@MonkeySpecs301]

good to know, i just bought the toaks pot and snow peak mug, thanks!!

[@hardwareful]

I shall eat ice cream from an insulating 300ml mug in summer so it actually gets some good use.

[@stalwart263]

Why not get a Soto thermostack? Cool ok the outer mug, poor to the inner and then join them into a double walled.

[@randomaccount9440]

So glad you made this...

[@korling99]

you can use that mug to melt chocolate now or cheese or stick it in a campfire for some awesome cheese dip

[@BackcountryExposure]

korling99 I've always wanted Backcountry fondu

[@MrDecennia]

Bought this exact mug with this effect. Any ideas on to how to fix or atleast have it stand flat?!

[@fish9468]

Lmao you fucked it

[@MrDecennia]

@@fish9468 I bought it for very cheap, so it’s not a big deal. Just want it to stand flat. Not using it for drinking.

[@vladimirjonas5516]

I am rather interested in: If I fall down and squeeze my single wall Ti mug between me and the rock, will it survive? No videos about it.

[@Syrup070]

“Please note: double-wall titanium cannot be used for cooking or placed over a heat source” Just like telling children to not look in the closet 😂. Thank you for doing the opposite!

[@BackcountryExposure]

@@Syrup070 just out here trying to win a Darwin Award!

[@TheWasatchGearReview]

I've never seen that done before! Good video Dev!

[@BackcountryExposure]

The Wasatch Gear Review thanks dude!

[@lucassutton5539]

Friends have had a Stanley stainless double wall mug on the fire one trip and it exploded but I think the titanium is such a strong metal that it could still hold the expanding pressure in the vacuum layer between walls (and a campfire is much hotter than a small stove and focused the heat underneath the mug not all around it). Your a brave man sir, lucky to not have been scalded by boiling water but I like the experiment, I would suggest some safety precautions for dangerous tests like these tho, but it is cool to see what happened to the titanium.

[@BackcountryExposure]

lucas sutton don't worry I wasn't a total idiot. I had glasses on and kept my distance.

[@jasonpetty3786]

The inherent design of an insulated mug (insulated being the key word) makes it a poor choice to cook with. With that said you are lucky. Some of these insulated type stainless and titanium mugs are filled with a gas to reduce thermal exchange. And they can easily explode and cause injury. If you do something like this again I would recommend some safety precautions. Distance being the first and keeping a potential explosion away from your house. Just my 2 cents. Keep the videos coming.

[@jasonpetty3786]

steppenwolf you had that mug sitting on top of a pressurized can of gas (Canister stove). Not really knowing what to expect as far as possible failure of the mug at a a minimum it could have knocked you stove over while still on. FYI the swelling of the bottom of the mug was due to pressure increase inside the insulated mug. I believe the only thing that kept it from failing was the water inside the mug. If you really want to see the mug fail heat it up without weather in it.

[@railwaystationmaster]

LOL

[@greenspiraldragon]

If it bulged the bottom enough to round it maybe it could explode.

[@kinpong720]

Anything can be done to restore to the original flat base?

[@MrDecennia]

Wondering this as well, anyone?

[@calmarcalmar]

You could make a very little hole into the outer-wall - or more. Then it would work at some point.. Still.. would take up long time until it heats up, as you figured out :)

[@adventureswithfrodo2721]

interesting​. do it a gain but get a infrared thermometer. did the inner cup bulged outward to match the outer cup. Need more investigation.

[@BackcountryExposure]

Adventures with Frodo no, the only visible deformity is the bottom of the mug. Otherwise it's totally normal.

[@live4wild968]

I was surprised that it didn't split the cup with the trapped air in the walls.

[@BackcountryExposure]

live4wild me too!

[@dougjohnsonbushcraftandbjj5561]

Vacuum sealed means there is NO air.

[@bloodseedrums]

Doug Johnson some people don't understand how insulated mugs work apparently

[@pozsmith8207]

At least you know it can be done in extremis.

[@thevideostump46239]

interesting..

[@camojoe83]

You come across as someone who would need to see this demonstrated to understand it.

[@BackcountryExposure]

Yeah I am kind of dumb.

[@steventhomas6831]

I am ashamed to admit the amount of anxiety that this video gave me lol. Cool patina… too bad the mug is useless now because of the bottom.

[@evilpoomonkie]

simple thermal dynamics

[@ngmui430]

which law? the zeroth?

[@eachday9538]

Basically what SpaceX is doing atm

[@franetoblues]

Thanks.

[@johnspaans1132]

Totaly pointless post, an insulated mug is definately not for cooking, so why would you?

[@TheWeekendHiker]

That is good to know. I've always used a single wall to boil with. Glad you weren't injured during the making of this video Devin. Take care. -ATB Adam 🐢

[@BackcountryExposure]

TheWeekendHiker thanks Adam!

[@spicecrop]

Nice experiment but an obvious total waste of fuel. I suppose it would work in a survival situation with a fire instead of fuel stove.

[@trg3761]

Guess why im here just wasted 80 bucks😩
