The Silent Killer In Your Backpack

[@kevinhodgson2085]

I use the can opener on a swiss army kmife to put loads of holes in my empty canisters, so they aren't just empty, but are visibly holed, so everyone knows they're safe.

[@whitefrog2]

Haven't had to cook in my tent yet, I think I'll be able to do it in my vestibule partially open. Great info as always! Thank you!

[@grimgranite]

That’s a great idea, stay safe! Thank you!

[@baan6981]

I love off grid and learned that cooking in my camper is kinda hard and still doesn't have the best airflow, I live in an area where when it snows, I mean Jack frost is literally jacking off right outside. So opening my windows isn't an option. So I made a outdoor kitchen. Just gotta keep snow from piling up about 3 feet.

IMPORTANT WARNING WHEN USING FLIPFUEL OR EQUIVALENT REFILLERS. You should only use one if you have a kitchen scale to weigh your cans and can confidently verify that you are not overfilling your can. This also means you have to know what your empty can's gross weight was when full, not all fuel cans have the gross weight printed. An overfilled fuel can CAN explode as ambient temperature and atmospheric pressures change. Where my refilling procedure deviates from yours is I weigh the empty can so I know how much needs to be added, and then I fill the empty can for maybe ~15 seconds at a time, disconnect and re-weigh, and continue topping off as needed. If you accidentally overfill, it's ok to drain some back into your "feeder" can.

[@kevinm1734]

That being said, I think it's a fantastic tool and I haven't bought a 4oz fuel can in like 2 years

[@mortenlunde1625]

Also, don't mix cans that are for butane only, with butane/propane cans, as they are designed for different pressures.

[@DarkMetaOFFICIAL]

when you said it sucked the tent was reaching equilibrium, it sounds so demonic 😂 BABE we need more CO in here, it's leaking out the tent walls 🤣💀

[@BackcountryExposure]

My heart hurts for the gear that suffered in the name of science. SCIENCE!!!!!!!!! This was awesome, Gordon!

[@grimgranite]

Thanks so much, Devin! Science indeed, haha! It was a torture test for sure. 😭😅

[@Matt61702]

The main thing I learned in this video is how good Grim Granite is at lighting. Look at the reflection of the light hitting his glasses frames and the reflection of the light in his pupils. Yet no reflection in the lenses of the glasses? Also no visual distortion of the background where you'd expect to see around his temple while looking through the lens. Are there even lenses in the glasses? If not... WHAT ELSE IS HE HIDING?

[@ak983625]

This why I would never own a home with gas range. CO, particulates, radon, NOx, other toxic emissions. Maybe ok for restaurants with massive fans.

[@alexpervanoglu7420]

If they end up in landfill in the US then they are not being recycled are they !

[@AlexHatlevig]

Great vid! Very interesting and informing. Ive always been aware of the dangers of CO poisoning but never have known what would actually be the point where I’d be in danger

[@grimgranite]

Thanks for watching! I read a study that said as long as you have about 2’x2’ square area of combined ventilation in your tent, it should remain safe. Sooo… just keep a door open. 😅

[@AlexHatlevig]

@@grimgranite makes sense! Good idea haha

[@RainerGolden]

This video is awesome!

[@grimgranite]

Thank you, Rainer! Means a lot coming from you.

Would love to hear some ideas on puncturing those canisters without using a $25 tool. I have not cooked in my tent and I hope to not have to do it. Good job pointing out the dangers even if you had to sacrifice your Jetboil and tent.

[@jonsanford2515]

Jetboil sells a tool called the Crunchit for $10 specifically for puncturing the canisters so they can be recycled. It screws to the threads and has a hinge and sharp point that allows you to easily puncture the can. You could also use a sharp tool you already own and a hammer. But, the surface of the cans are slick, and It takes a decent amount of force to puncture them. Pretty easy to have the tool slip. If you go through enough fuel cans it’s worth $10 for the convenience.

[@grimgranite]

Thanks for watching! There are lots of ways to pierce those cans… perhaps a video on that topic might be good!

[@memathews]

Great video! Probably the most dangerous part of cooking in your tent/vestibule is when the critters come visiting because of the aroma. It's really best to cook and eat 100 feet of more from your tent. Either that or make room for small furry night visitors.😂

[@grimgranite]

This is absolutely correct! I sense a follow up video. 🤔 Thanks for being here!

[@UGA.D]

Great video! With regard to the FlipFuel, is there a concern regarding overfilling? Seems like I remember reading something about constantly weighing the receiving canister to make sure it isn't overfilled. I don't have a FlipFuel, though, so I hoped you could weigh in on this one (no pun intended.)

[@jmash41]

I understand you wanted to do a thorough test. But you went to the extreme.😂 If some people cook in their tents, its probably for brief cook times. Thanks for the tests!

[@mikehikes710]

I dab in my tent using a propane torch. There no way a tent is air tight enough to have enough carbon monoxide to hurt us. Unless your wrapping your tent in saran wrap or something. Just keep the window open if anyone is worried lol

[@drytool]

Think of alpine expeditions.

[@roxrequiem2935]

I don't think its these cookers that are the issue. I think its those gas operated portable heaters. I'm not sure, I'm from the tropics so correct me if I'm wrong. But those things has to have some sort of combustion and exhaust, and in turn suck up the air, heck maybe a combination of a gas powered heater and a jetboil is the culprit to the lack of oxygen and buildup of monoxide.

[@danieljones2183]

excellent PSA

[@rogercrum7339]

Great video and tests. Sorry about your tent though.

[@joewinfree9814]

*DISCLAIMER* Pandas were sacrificed in this video

[@Sanji-TG]

YEAH

[@bernielamont825]

I'm not a rocket scientist from MIT, but I know enough not to cook inside a tent. Kinda don't feel sorry for someone getting sick that way.

[@grimgranite]

The curse of knowledge! Not everyone knows these things.

[@drytool]

You clearly aren't a mountain climber either. Thanks for displaying your ignorance.

[@LuisDiaz-i7l]

Who cooks inside their tent.🤔

[@grimgranite]

Quite a lot of people, as it turns out. 😅

[@drytool]

Mountain climbers, quite a bit.

[@LuisDiaz-i7l]

@@drytool oh, that makes since. Thanks

[@OwenM476]

Who cooks for 30 minutes on a gas stove in a tent? Not a realistic test.

[@grimgranite]

Most people probably wouldn’t cook for 30 min in their tent, correct. The rest was about finding out what it would take to have lethal concentration of CO gas in a tent. As you can see, it takes quite a long time and blocking off a large area with snow, etc.
