The pedometer is a portable device that measures a person’s physical activity level throughout the day. Pedometers are affordable, reliable, and can be used as a motivational tool. Though they are designed to be worn at the waist, they can also be worn in other locations, such as the arm or ankle.These early pedometers all looked remarkably like pocket watches, so close were they in design to the time-keeping devices. In the 1980s, promotion in Japan of a manpo-kei, or 10,000 steps meter, gained national popularity, and a wave of digital pedometers came flowing out of Japan and onto the world market.

No one firee a flare gun into water, literally no one, unless you’re in a sea, ocean, and a submarine is looking for you and they have someone who can see heat signature,
Just vullshit
to any one wondering petarda is basically a ukrainian/polish world for firecracker/firework
It would be reasonable to suggest an idea that in one of the previous videos a gentleman who has irradiated himself from the Metal Claw is now doing not very well. The translating staff member or the channel manager would rather prefer to keep it secret. A strategy to upload older footage is not bad at all.
I hope those previous statements are incorrect, and that this is not the end for those humans or even the channel.
Hello I’m new In the beautiful channel of yours
asking you a 3g 4g gun succeed in North Africa??
Internet expensive Here
Maybe not a great idea to make Big Bang and explosion near war zone��
U cannot use flare gun at water as gun won’t come into hands ��
Такое дерьмовое видео я бы даже не выкладывал,а другим людям походу всё равно что смотреть,херею с этого народа
Good Show and Fascinating! But don’t try it too much, it is polluting the environment.
Don’t think that you cocked the hammer on the second attempt
Wait but the Sonic game I played let me hold my breath for 10 seconds but I didn’t have to go up for hair I had to get underwater bubbles wat sense does that make
I would like to see some of them launched above the ice, to see if it will glide across the top of the ice.
Bruh u are supposed to fire in the sky and wait for your super air drop
Yes it will fire that is what you use to light a welder under water
would anyone be able to explain how this relates to chemical equilibrium?
You need to get some condoms to put on fireworks to stop them getting wet, that’s if you know how to put them on hahaha
3:50 everything’s impossible. Me: calls mom I can’t make tacos anymore
It is supposed to monitor you while swimming. OF COURSE it is water resistant…
Sooo cooool, I didnt know that they still burn underwater! I Learned something
today! �� ��
When I was a kid I did this with two garden hoses attached to a snorkel mouthpiece with a y valve. One for breathing in, one for breathing out, taking out the issue if CO2. They were floated by some bottles attached to a milk basket. It was a ton of fun!
Please, if you want to dive, go to a diving course, and listen to what your instructor says. Dont do something because you saw it online
Hydrogen and oxygen under pressure? Better hope nobody lights a cigarette near that tank.
WHY is the amount of oxygen in our lungs 5 times higher at 5 times higher pressure? How does external pressure INCREASE the intake of oxygen? I can’t understand.
Get bottle,one of those plastic pipe thingys,glue,swimming tube
Cut off a part from the swimmming tube then glue the plastic pipe to the bottle wait until the glue dryies and tadaa
You have a great talent for neatly fitting lots of information into a short amount of time without overloading the viewer
Too many informative video challenges fail to strike this balance. Many tend to barrage the viewer with far too much information far too quickly, or they take too long to say what they want to say. Many more can have a 5 minute+ videos that don’t say much at all.
Keep up the good work.
Your smile makes me laugh ������✊��✊��✊������������������������
This is the most dangerous idea I have ever seen if anyone thinks it’s smart go ahead and try these thinks
It’s natural selection after all
Very well explained but i didn’t understand a thing, i suck at Science
Coronavirus first thing I thought when I heard that cough LMAO just kidding
then do they swap tanks as they come up to the surface? Or is hydrox good for all depth? thank you.
Keep destroying the resources of nature & natural life & do this experiment at ur house room doors should be remain close when u do so.
take a look at all this trash,,, matter of those guys:D….. looking like some real super neard freaks
If we could take in more oxygen our body’s would work a little better but to much oxygen is bad epically in large intakes
Small mistake nevertheless impactfull….at 50m under sea level the ambient pressure is 6 bar, 1 bar atmospheric pressure at sea level and 5 bar hydrostatic pressure, means 6x surface pressure…basic scuba knowledge…��
I wish we were up to actual date not 4-6 months behind the normal channel
Oh my goshiness! Can you guys lose that dork translating laughter and killing the videos. All developed countries use subtitles.
Holy shit. I scuba dive myself and never knew about much past nitrox. Breathing almost pure hydrogen seems crazy!
Hydrox Cookies? They breath cookies? I wanna scuba dive now.
Hey tamil friends…this is also good explanation..if u want see this
https://youtu.be/TC08zIAqPLM
0:47, 0:54, 1:20, 1:44, 2:10, 2:34, 3:07, 3:44, 4:00, 4:22, 4:48, 5:40, 6:14, 6:48, 6:57:???
6:14: Festival splash
Can you use these to scare off wolves? Like throw one outside
Wish that i dont need to breath:P ik its impossible bwat idk
So hardcore divers breathe fuel-rich rocket fuel? That’s even more hardcore!!
girlfriend: hes probably out cheating on me
boyfriend with the boi: throwing firing works in water.
I am indian and I look this video my doubt is clear��❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤��������������������
Hello from the future. Somewhere on that day somewhere in the world, seismometers were going crazy.:)
All I see are people that want to dry their phones in a microwave and eat lead paint chips so… swim in the shallow end of the gene pool!!
1:50 it takes balls to be in the water with a great white and shoot it with a spear gun
Why didnt you just find a swimming pool got in it and try it. Wouldve been easier than rigging sl that.
You are all in Russia & you are going to have a better 4th of July then we are, despite it’s not even Russian Holiday! Gr8 stuff. I love fireworks! God Bless y’all…
Thanks for sponsoring coke aka the company my dad is working in.
2:48.. dudes high as hell.. seen the most amazing of explosions of all time.
2:35 thought I was watching the Beverly Hillbillies again, up from the ground come a bubblin’ crude, oil that is, black gold, Texas tea
Seems like the kind of guy that lives with his mom and beats off with a puppet
you can get a used perfectly working diving gear for just a few bucks and with this equipment dive up to 120 minutes. Enough time to collect 2kg of gold nuggets
Ice was too thick shoot them along the shore not towards middle stay where its thinner maybe.
Please please fire it on a water level… So that after burning sometime it will come in contact of water and then… We can see what happens next
�� ����������������������������������������������������������������������������������������������
I love fireworks.. But do you think of the creatures in the water? You are selfish.. How can you be so merciless with the environment.. There are limits and you cross them by being ruthless to nature..
1.kill a fish
2.cut off there gills
3.glue the gills to ur face
4.boom now enjoy the same breathing time but now look like an Arabian/latino/asian/african/middle eastern/European gill fish
We dont discriminate here
uh this was much more complex than i initally thought thanks for making this! =)
The most amazing thing about this scuba is that it works
yeah that’s kinda necessary
its a death wish.. why do this when i can go in my pool and have no problems at all
There is ONE main reason why you have 8200 thumb downs.. have you figured that out yet?
I thought the video was gonna be about literally breathing under water, like breathing while submerged in water like fish. it’d be great to do a video about liquid breathing maybe
I want to learn and make one.
Can you please recommend any reliable source which I can refer for knowledge?
I think the flare gun will fire but there will be no red stuff on the flare piece of metal
What happened to the guy at the end when he came up for air?
1500 dots condom working properly underwater breathing successfully.������������
That is dangerous. You have to know atlest about the scuba danger.
Just hearing that 30 meters is “relatively shallow water” has only told me that diving isn’t gonna be my thing
3:45 everything is impossible don’t you mean everything is not impossible
Are you crazy?. in my country they send you to prison. You pollute the environment, and you kill fish ��
I always thought helium made people a bit high, i guess i was wrong. Great video though!
6:18 Nice reaction acting since like 1 sec before he had his arms flolded lol
OH MY GOLLY GOSH!!! CHILDREN LOVE TO PLAY WITH FIREWORKS, YOUR GETTING BORING NOW!!!!
Isnt Hydrox explosive? Wouldn’t it explode just because of pressureizimg? I know on Hydreliox the helium prevents the oxigen and hydrogen to react to water.
When your mom found a condom
Me:i was breathing underwater with it
he saidc he covinced the viewers every thing is impossible LOL
Wanted a video that explained depth vs gas mixes out of curiosity. Its crazy how much the game changes the deeper you go. Gases you consider harmless start to kill you. Nice video and channel man.
I’m not a hater of this guy, I loved his content.
But why this person often Laugh weirdly without reason, he fixed the pin of flare gun & tried firing it then laugh “does he have loose screw” btw that other guy behind the camera he is lovely “I’m Ready”
Guy: buys condoms
Pharmacist: having fun tonight?
Guy: yes I’m gonna learn how to breathe underwater
10 thousent ����������������������������������������������������������������������������������������������������
2:56 Having hydrogen and oxygen in the same mixture doesn’t sound like a good idea.
Please make more Pripyat videos I miss your beautiful apartment. I hope Anton is well.
The fireworks in the uk are crap thesedays. back whe i was a kid though they were like the ones you guys have. they ban everything thats any fun here.
I was browsing YouTube for a good video that can explain this, and this is the only video that I got with good explanation
Next time try to throw an atomic bomb in the river to see what it does.
Just kill the illusion version of the corrupted monk and get the mibu breathing technique smh
2 ways to breath underwater
1. grow gills
2. get a fucking suit you turd
Speak slowly..
This is not an advice but a request…
Informative..
People should check out “TheOftler” here on YouTube if you like to see stuff like this.
when i was a kid every time i went to the swimming pool if just go to the deep end and float under water until i ran out of breath and came back up. scared my parents half to death every time haha, but now i can breathe pretty long underwater
Who’s idea was it to mix high pressure hydrogen and oxygen? I feel whoever did is now exploded.
no wonder there is no fish with so much trash in there. good job russia
Moral of the story Humans weren’t meant to be sea creatures.
Just a suggestion, If you try so try it in your own pool, if so pollute the environment
Is it me or does he sound like the guy off of fnaf sister’s location
Tittle 5 ways to breath under water
Talks about world records.
Is it legal to shoot firework in russia under the year? In Austria is jt. But there are every time people get angry, everywhere.
There actually is a liquid you can breath in because it has enough oxygen

Before like 6month ago so I tried to hold my breath by going in the water but I think wait there is oxygen in water right so when I under water I try to inhale the water and exhale it ok ok I’m not that smart
The ones that have pumps aren’t scuba they are hookah scuba is self contained underwater breathing apparatus
3:47 he convinces the viewers that everything is impossible
Sorry, i don’t like this, because you are polluting water, and it is ver harmful to living things under water��������
I heard they invented that liquid that you fill your lungs with and you can breathe underwater this was back in like 2000 something. well its like a gel you fill your lungs with. Gives me anxiety just thinking about it
Man I wish I could get you guys to get me some of all you used in this vid I’d love to try the same but I can’t get them where I live but would love to have some fun at my lake
If we can breathe in water then tsunami will be fucked up cyclone
Greetings from Pripyat, today we will restore this flat as new. an they did, modernized even.
Just when you thought an air type is good, there comes a problem with it ��
I just know these two have never had a girlfriend and never will, oh my gooshhh
This is one of the applications of henry’s law I couldn’t understand thanks for explaining.
Man, after all the reading this short video explained it all and I finally get it… awesome
I stopped the video and I think it actually fires. It have to be waterproof.
How to breathe under water forever
1. Kill a fish
2. Cut their gills
3. Apply it to your face or replace your lungs with gills
4. Enjoy
I told my class about heliox nitrox trimix and none of them knew what I was saying
you should go to chernobyl and renovate more places.. maybe try making security systems? like paint traps or smoke bombs
Hey I love the video and love how you put it in English I thank you for that
teacher: why are you laughing?
me: nothhhingg
my head: 2:13 oh my goshy!
Best video I’ve ever seen capturing the aspects of Rec and Tec diving straight to the point. Brilliant… well done! <3
What if you cant afford a tank ThEn dOnT Do It well why do you thank they would have asked for anything like that oh yes CAUSE THEY WANT TO this is easy ways to do that also this was probebly made beacause people were bourd and COULDN’T AFFORD IT like come on aswell as sintce
( 3:46) “…and with his feet on land later, he convinces the viewers that everything is impossible”?
Eh?
What?
That makes no sense whatsoever.

Add 50m ambient pressure is not 5 times, it is 6 times the atmospheric pressure. Please correct that.
Done same when I was kid around 11-12 but we used to put under 30-40cm ice. The most impressive one was which left the ice cracked of around 3meter radius. Although the ice was still okay to walk on. Great memories!
Very interesting video. I watched a video recently about a driver who had was at the blue hole. He had a pure oxygen tank and drowned at the bottom of the ocean floor. The video narrator briefly explained narcosis and oxygen toxicity and I was intrigued but also thoroughly confused. Thank you for this information! The one thing I’m still not getting is why the amount of oxygen and nitrogen increase as we go down deeper in pressure. Do our lungs shrink down there??
Having gills would solve this problem completely as you get oxygen through water. If that doesn’t work than I guess we would either have to genetically modify ourself to tolerate high amounts of oxygen or nitrogen or have gills but also carry some oxygen tanks around.
Oh and also collapsible lungs, so it wouldn’t matter if they implode and also regeneration if any damage do occur.
So I’ve got a question. “at 50m the ambient pressure is about 5 times as great as the surface pressure, this means thr lungs will contain five times more oxygen than they normally would”
Now we’re talking about the hydrostatic pressure, right? The pressure acting on the outside of the diver, not on the lungs? At least that’s how I imagined it. I thought we have really high pressure air in the tank on our back, that we then convert the air through some clever plumbing and valves into the same gas at lower pressure, which we can then breathe in.
The hydrostatic pressure can only compress us from outside, making it harder to increase lung volume by inhaling
I think I’m terribly wrong now
Small correction: At 50m below the water surface the pressure is ca. 6 bar (atmospheric pressure + pressure from the water column). (Around 1:32)
Tip Fire the flare gun towards the sky to make sure it is seen by planes
����������������
The clip of the guy running underwater is from “runnin” by beyoncé
I loved this video! I’m taking my nitrox speciality soon! If you fancy a good laugh, google saturation divers on helium singing, they sound like Alvin and the chipmunks! ��������������
And then, the fire brigade is called to extinguish fire created by two ‘tards.
5 ways to breathe underwater
a bunch of pro athletes who practice not breathing
Holy crap, and here I thought divers just used tanks of oxygen… this is so much more complicated that it makes me wonder how we got to understand all this in the first place!
and i used the think that oxygen tanks contained only oxygen…
Yeah, few of these are actually SCUBA: That stands for self contained underwater breathing apparatus: If its connected to the surface, requires another person, basically if you can’t wear it on your back its not SCUBA
Love your videos, and especially your eloquent delivery. Always learning something new. Keep it up!
Very cool video, and the fact that an ad about learning to dive came on before hand really has once again awakened my interest in becoming a SCUBA diver: an idea which pops in my head every couple years.
At around the 2:30 mark, I couldn’t help but feel this had become an ad for some new drug on the market. I guess it was the combination of a disorder, distilled down to an acronym, the tone of your voice, the background music, and the, “we still don’t know the cause but (insert brand name sounding word) can help.”
I had to go back a couple times afterwards, and rewatch the end, before I could get past that point without my brain switching into, “ignore the ad,” mode. Haha.
Fun science project kids: Take a Hydrox tank, open the valve, light it on fire and you have a Rocket!
That’s pretty wild that someone can breath a mix of mostly helium with just a touch of oxygen. I guess the important part is that the necessary percent of oxygen is there.
I always look forward to your next video. Can you do one with Kerbal space program you have not made a video with it in a while
Actually we have made breathable liquid, the US Navy has made it, it’s called a rebreather
Could you put the dates of the original videos? Sometimes it’s confusing that they are in the wrong order
The flare gun was aimed at cabron when you flung the string. Careful my friend. Tio is the main character for me no offense and I want him around
Well that’s five minutes of my life waisted that I won’t get back, talk about anaemic,
Why not use oxygen tubes put on end in yiur mouth the other end attatched to an open ended container that floats and the other end of the tube sticks up out of the water in the floating piece so you can constantly breath as long as the other end is above water kinda like an extended snorkal
So the first thing I notice is that you are putting trash into that creek…. Great job… You are polluting the water with your trash and not only that, but you are probably damaging the wildlife that live in that area. Its people like this that make our world a crappy place…. I hope you went back and cleaned up all that you threw in there… Probably not… So sad.
If we are gonna be fish thats gonna be fishy
Get it?
Ok no
Ok stahp
STAHP
Thanks Randy, you are legit the only one who explained this concept so well! Thanks mate, now I don’t feel like an idiot
Why do you doing all these stupidness all of the things that we we said is natural disaster it is man kind do that,
The world record dive is 2300m. Not 300m. Its important to mention this…scuba isnt the only form of Diving
If you were to open a Hydrox container at surface level, wouldn’t some of the oxygen and hydrogen combine to form water?
Does the high pressure when diving prevent this reaction?
4:50 This was an epic explosion and everyone is an arsonist and likes a good boom boom!
I’ve done this. Used a plastic pipe to launch under edge of ice.
Happy I stumbled across this channel. You got cool videos, man.
