Submerged for 24 hours, in a Submarine I Built. Will I live?!

We finally took on our biggest video yet and raised the stakes! To celebrate reaching 135K subscribers, I’m attempting a 24 hour challenge - staying underwater in my homemade submarine. If I can’t do it, I have to give Chris and Nicole $10,000!

What is sad is that this video only has 20K views 1 month after posting. This is like a Mr.Beast challenge but in a literal homemade submarine. AWESOME video. DESERVES WAY MORE VIEWS. W-t-h Youtube!

Babe the cartel called they want their engineer back

[A.C.Lawrence]

I cant believe you brought that thing here all the way from North Korea.

8:56 bro builds a literal submarine but has to stop and think about what diamonds are made of

It's fun and all until you hear "Warning: Detecting multiple leviathan class organisms in the region"

[DanRedReddington]

is there a way to open the hatch from the outside? i cant seem to see a way to do so. i hope you thought of a way to rescue you instead of having to rescue yourself. 🤔

You've broken 100k subs so you obviously have a basic idea what you're doing on YouTube. This is also the only video of yours I've seen. However, I personally gravitate towards technical and documentary content, and don't care about a bunch of silly "challenges". I am actually really interested in how you got where you did with the sub, as well as where you're going. Similar project channels might be "Robot Cantina" or "Alex Hibbert" when he was working on his life raft Alan. Even if you're not actively working on the sub, but using it / practicing with it, there are ways to show that off.

Personally, I'm a lot more interested in your plans for dealing with condensation and battery life than you opening up the valve for no reason.

Either way, I'll give you a like and a sub and hope things go well!

I can tell you put a lot of effort to the submarine, others use cardboard or plastic but you actually put the gear needed to survive

[easygurps]

Watching you throw food up and catching it in your mouth gave me a mild panic attack at the thought of it getting caught in your throat and choking to death, while alone, underwater, in a DIY submarine. I love your adventurous spirit!

0:53 "do not try this at home", first of all how the heck do we get a submarine and second nice video bro

[Wofel]

This guy needs way more attention! Love this video🎉

when the harpoon anchor was thrown I nearly had a heart attack🤣

Given the limited space and resources inside a small, one-person submarine, a practical waste management solution could involve a gallon jug with a hose and funnel to create a sealable urinal. For solid waste, a composting system using a 5-gallon bucket with a toilet seat, combined with peat moss or sawdust, would provide a sustainable and odor-controlled method for waste disposal in confined quarters. This setup ensures efficiency and minimal environmental impact, essential in the constrained environment of a submarine

As an ex-submarine sailor I'm curious how he removed the carbon dioxide from the air. Normal nuclear submarines have devices called CO2 scrubbers which is a chemical called Ameine(sp). Call Amin has the property of a absorbing CO2 and then it is put in the boiler and compressed overboard through a diffuser.

The water that you let in...
Do you pump it out with a water pump? Increase the inside air pressure to push it out? Or leave the water inside and adjust the buoyancy to compensate?
Did the battery voltage become low because of pumping that water out with an electric pump or for some other reason?
How much water could you allow in and still have enough buoyancy to surface?

Cosmetic addition idea: add a system that will announce certain things as there happening, sort of like the cyclops from subnautica, with it announcing “diving” or “surfacing” or “welcome aboard captain, all systems online” when you open the hatch

You could have made it if you had John Ball outside. I once saw him carry 6 x 80 cu ft tanks. Holding two in each hand by their K-valves, and one under each arm. Dude carried them nearly a mile, uphill to our mountain lake dive site. He wouldn't even accept a tip!

Interesting! Congrats on outlasting Nicole and Chris:) The nerdy in me will have to ask a few questions. Do you have provisions for pumping water overboard from the living space? I'm guessing you are using lead acid batteries so do you have a backup electrical system? An IP65 or IP68 rated LiFePO4 power station could easily handle all the subsystems for 24 hours or more without affecting the main battery bank. As you are using O2 (I agree with using medical or HP grade O2 BTW), do you also have an O2 meter in addition to the CO2 meter? With an O2 meter and a bleed valve, you can maintain the O2 levels close to 20.68% to ensure you aren't increasing the odds of a fire. An lastly, maybe a nice addition would be a way to dehumidify as all that extra humidity is coming from you. Yes, power hungry but you don't have to run it all the time. Hope to see more adventures next year and upgrades that you might add along the way!

I saw the "RIP SCUBA STEVE" sign and started welling up. I had a good friend, a festival buddy from Nelson Ledges Quarry Park that was legendary and known as "Scuba Steve". I miss that man, and would like to imagine this was meant for him. Much love everyone!

Круто, дуже класно побудувати таку річ самостійно!
