This Mini Scuba Tank Fits In Your Pocket V2 Twice The Air Lights Lasers 007 Star Wars

So you guys really seemed to like my last James Bond mini scuba tank. We read your comments and it looks like we need a version two. Speaking of comments though, definitely type your ideas for what I should build next. Also, we're gonna be going pretty hard with this video. So if you wanna toss a like and subscribe, that'd be great. So if you caught my last video, we kinda teased we were gonna do this. Along with some other vlog stuff, which you guys really seemed to like, so we're probably gonna do more of that. But this like small mini breather is actually more popular than I thought. I know it from James Bond, but I got a lot of comments saying they know it from Star Wars and a bunch of other places. So just a quick recap for those of you who didn't see the last version of this. First of all, just go watch it. But basically I built a mini scuba tank originally from Thunderball. It's made of two CO2 air cartridges. We emptied out, that part's important, and filled with just regular air. And we used some CO2 bike adapters to do this. Now before you say this is super dangerous and to never try this, you're absolutely right. Obviously scuba diving is dangerous, especially if you're using like DIY stuff like this. I actually went through like 100 reasons in my last video for why you shouldn't try this. Some of the main points include lane expansion while surfacing, nitrogen buildup in the blood, and potential contaminants from the gas. So like why am I doing this? Well first I'm gonna be taking every safety precaution we can, but like also because it's just an extremely cool project. Are you kidding me? This stuff doesn't exist. Also it's a little less dangerous when you consider the fact that we're not diving very deep, no more than 10 feet, and only down there for a very short period of time. This means low nitrogen buildup and less air expansion when you surface. Point is, don't try this. I'm doing it so you don't have to. And like I really just would hate for anyone to get hurt as a result of this video. So you know, that's not what we're trying to do here. We're trying to put out positive energy. Try to inspire people to get creative because that's something I really value a lot. But you gotta do it safely and know the risks. That being said, to give a little of that creative inspiration, here's some projects that you guys built and sent to me on Instagram. Definitely keep this up guys. I love seeing what you're building. Take videos and send them to me at jlazervideo on Instagram or email works. All right, so this gadget's actually kind of hard to make practically. Like entire companies have tried and failed. The main reason being the huge amount of air required to fit in these tiny little cylinders right next to your face. Like they are literally CO2 cartridges according to the prop team from James Bond. Did the calculations in the last video and it turns out the pressure required to fit enough air for what they did in the movies would need to be about 150,000 PSI. Not easy. Like if we actually use standard CO2 cartridges, their rating's about 800 PSI. So with that, we only really get a couple of breaths. Like with the last version, I was able to get around I think four or five breaths with two cartridges. And when I was really trying to conserve air, I was able to stay under for around four minutes. So in this version, we're gonna try and do some upgrades. Try and get a bit more time underwater while still keeping the design relatively small and cool looking. Also, I'll try and add some other spy features like lights and lasers because you know, that's kind of what I do here. So for this new design, we should be able to increase the time underwater by just adding more tanks. Like we should be able to fit two more tanks on top without it taking up too much extra room. And it should still look pretty cool too. So I hopped on SolidWorks and did some remodeling to accommodate for the extra tanks. Then I ordered a few more of the smallest CO2 bike pumps I could find. I went with the metal ones because hopefully they're gonna be a little more durable and hopefully handle more pressure. So the threads in these CO2 bike adapters can handle CO2 cartridges that range from about eight grams to 25 grams. You can interchange cartridge sizes depending on how much air you want underwater. First, the actual size of this thing. And we could in theory go even bigger. Like they make cartridges that go up to 72 grams or even higher. But honestly, at that point, you could just get a mini scuba tank, like spare air or something. So it kind of defeats the purpose. So I think a good sweet spot is sticking with four 25 gram CO2 cartridges. That gives us a total volume of 120 cubic centimeters. So if we do some rough calculations at around 800 PSI, the air tanks can hold around 1 1⁄4 of a cubic foot of air. It should be good for around 12 to 15 breaths on land. So that'll be a little less when we're underwater. But that's twice as much air as we had last time. So in the James Bond movies, I think he was able to stay under for around five minutes, but he was moving around. He was using up oxygen. Looked like he was kind of deep down actually. So with this device, I think we can crack the same five minutes, but we're gonna be much shallower. And I'm gonna really try and conserve the air. But I think we can do it though. So on the top of this device, just like last time I included a one-way valve. Now this is super important because if too much air ever rushes in to the device from the tanks, it'll blow out the top instead of going right into your lungs and potentially popping them. So I printed that top part and then the bottom piece to hold the other two tanks. So if we wanted to use larger cartridges, all we'd have to do is print a wider spacer. Also in the last version, I didn't really do anything about a mouthpiece. It was small enough where I could just bite down on the thing. But in this version with the two extra tanks, it's too wide. So I 3D modeled and printed an adapter that has like a snorkel mouthpiece that just slides right on the front. Actually in the movies, they also made two versions of the 007 Mini Breather. One with a mouthpiece and one without. So you know, we're kind of keeping it authentic here. Now another idea I had is because now we have four tanks, it'd be cool if we could open all the four tanks with just one lever. So I modeled and printed some sort of like mini pulleys that would sit on the back of the tanks and take the rotation from one of the valves and disperse it to the other three. Now this did have some potential, but the problem is we have to fill each tank separately. So we need each valve to be independent for that. So it might end up being more trouble than it's worth. I also thought it'd be really cool if we put some underwater lights on this thing. I feel like that might be useful if a spy ever had to do like some night recon. I also had to build an underwater laser watch to go with this. So here it is. It is a bit bigger than the last version, but definitely still portable enough to fit in like a jacket pocket. Plus you can take it apart to make it really small if you ever needed to do that. But to pump up the tanks, we're using a super high pressure hand pump and an adapter so you don't need any other fancy equipment. Now this pump goes up to 3000 PSI. We're not gonna go that high, sticking around the 800 range because that's the CO2 cartridge's rating. So each tank takes about 20 pumps to fill up. So that means you can fill up the entire thing in a matter of minutes, which is at least one good thing about having these tanks be really small. Like if you tried to pump up like a regular scuba tank this way, you'd be there for days, honestly. Also we got the built-in lights and the laser watch to top it all off. Am I forgetting anything? Oh yeah, kids, don't try this at home. Go to a friend's house. I'm kidding. We are actually gonna go to a friend's house to test this. They have a pool, come on. So as you see, it only takes a few minutes to pump this up fully and you're good to go. And of course, we can't forget the lights and the lasers. Do it for the vibe. I also did an underwater test to see how long we could stay under. If you remember last time, I got around two minutes and some change with no assistance and four minutes with the last version of the tank. So let's see if we can break five minutes with this thing. So as it turns out, the mouthpiece did leak a little bit because in order to pump these up, we have to get to the valve so the mouthpiece has to be removable. So every time I tried to take a breath, a little bit of water would leak in. I'd, you know, inhale some water. That really throws off your concentration. So I bailed at like three minutes 30 without using all the tanks. But then I sealed it up better and gave it another try. And I ended up staying under for five and a half minutes, which is pretty sick. Like I was definitely breathing real slow, trying to conserve air, trying not to move at all. But we got it, so I'm happy with that. Well done. Plus the lights and the lasers just look so sick underwater. Like it literally felt like I was in a movie. All right, but being a spy, it ain't all fun and games. Like last time I had to escape some bad guys by doing a pretty sweet bridge jump. But the guys following me, they found me again. So this time I had to step it up a notch. Damn, son. Yay, laser video, I love it. Yes, let's go. How was it? I would very much do that again, dude. Just rode some jet skis. I think it went well. Dude, we were out there and you couldn't see anything. And it literally felt like you were in a video game because there's nothing around. It felt like some GTA type ----. It was like if you fell off, you felt like you're gonna regen like in a video game. Right as the guy was like, all right, we gotta go in. GTA got a big old dive. ------- tux with a drone chasing you, just ripping the jets, dude. But I'm gonna ride out these spy vibes a little longer. Put on the glasses, I don't know. All right, well there it is, guys. 007 Star Wars mini breather version two. Remember, don't try this at home. Like if you wanna learn to scuba dive, definitely get professional help. But really happy with how this one turned out. We're really upping the production value. So please hit that like button if you did enjoy this and also subscribe if you wanna see more stuff like this. And don't forget to let me know what I'm building next. So thank you for watching. Catch you in the next one. Peace.
