Mum saw me trying to buy needles, razor blades and salt. I said I was doing science and now we're having a intervention for "my drug problem".... Thanks Roman

now show us how to make a mini hydrogen bomb please

I have been looking for similar videos and finally found it, thank you so much

A few thoughts. Thought 1, is if the blades were vertical, the bubbles would flow to the top faster. By separating from your plates, your plates once again come in contact with your electrolyte and can begin making the next bubble. Second thought is about voltage efficiency. The ideal voltage is between 2 and 2.5 volts, as you drop down below that voltage the production drops off. As you raise above ideal, you still get more bubbles, but, in addition, more heat is produced. The further away from ideal, give you less and less efficiency. If you have 5 volt source, you should use a neutral plate (plenty of google explanations). So, plate 1 is positive, plate 2 is not attached to anything, plate 3 is negative, then repeat. The 5 volt total difference is broken down to two separate segments of 2.5 volts. Obviously your goal is not to make the most effective industrial grade tool, but, with very minor tweaks to your design you can improve efficiency. Since there are fewer connections, its actually slightly less work as a side benefit.

this project also produce a gass called cl or chloride and is a toxic gass used in the cleaning industry. so if you would make this project use it ONLY outside

You should NEVER do that using a glass container: you'll end up with an explosive mixture of hydrogen and oxygen in that container, so you have quite an important likelihood of a backfire that will make the container explode. If it is made of glass, the explosion will cause glass shrapnel, which can be deadly. (a colleague of mine took a glass shrapnel to the throat a few months ago, and almost died of what was otherwise a very minor explosion) Plastic is much safer for this.

Your videos are so cool roman. Keep up the good work. :)

Thanks man! That was an interesting project! Im subscribed :)

Mum saw me trying to buy needles, razor blades and salt. I said I was doing science and now we're having a interv

Roman let's go bowling

You my friend are my current favorite mad Scientist! Cheers and nice work on the video. Thanks for the tips and idea! Rock on!

I love watching your videos Roman and I do this kind of stuff in my electronics lab at my parents home.

I would make it to generate the hydrogen and oxygen to separate sections to be mixed at the tip. - Just like a real oxy/acetylene torch. Sodium carbonate might be better electrolyte. I thought of making a setup with the carbons from batteries such that the container would float and when certain amount of gas is generated the carbons would be lifted out of the electrolyte. The weight of the containers would provide pressure .... etc. Your setup could blow up pretty easily.

The use of untrue photos in the thumbnail is getting a bit annoying.

Gostei do vídeo e da extrema criatividade com simplicidade. Me inscrevi antes de terminar de ver o vídeo. Parabéns. I liked the video and extreme creativity with simplicity. I signed up before you finish watching the video. Congratulations.

Thanks man. I've been looking for a good scaled down model of this to build. It's a weird science because technically, you could have stuck the metal rod at the end directly into the power supply to make it glow red. It's making large amounts that we need. Can you now use a 12 volt bicycle pump to compress the hydrogen into a container, for use say, on in small motors or explosions ?

Me- carrying the whole thing in my backpack Friend- got a light dude? Me- yeah, wait a sec

1. What you are generating is a mixtureo use of H2 + 02 in a 2:1 voluminar ratio. 2.For pure Hydrogen gas, you have to use a bottle with caustic soda solution into which aluminium pieces are added. This arrangement will work giving good volumes of gas at low pressure. However, be careful to avoid flame. Once I had an explosion, when I was experimenting as a kid. The bottle burst and corrosive alkali was splattered around the house. The Aluminium gets converted into a highly viscous gelatinous salt called sodium-meta-aluminate. 3. I wish you come up with a design that separates the cathode and anode using some membrane that can withstand temperatures of 100 degrees + because at higher currents the water heats up as well. 4. You must not put a great deal of salt in the water. A pinch of salt in 1 litre is more than sufficient for conduction. If you use more salt, you are actually generating Hydrogen along with chlorine at the anode. The water will turn alkaline as the sodium ions will react with water to form NaOH. The chlorine will generate at anode and corrode the electrode. So you have to use carbon electrodes.

i like the idea, the realisation, and the style the video is made. thanks, subscribed

"and some salt" **holds up massive container of salt**

Very cool project! But I have to mention, it is a HHO-generator, not a hydrogen generator. Thank you!

razer blades! super idea!! so mini and so effectful! great! thnx for your inspiration!

Awesome work. This is inspirational for me to make something like that. Would be great to make a soldering iron for using in soldering microchips or as a hot air gun that does not directly connect to electricity. Adding too much salt will make your flash-arrestor (clean water bottle) build up HCl eventually. There is clearly Sodium colloidals that would be making NaOH on your electrolysis jar. A drop of lime or vinegar instead would also help the electrolysis while slowing any discoloration due to waste chemical build up - since those are organic acids; which are slow to react since they are large molecules. Just my two cents.. Simply, I think you have put a little too much salt to the jar.

hot glue ia going to melt when it heats in use... use epoxy...

Отличная задумка, хороший канал как и на рускоязычном сегменте твой))))

I like this design. Did you try using a drying agent toward the end so you have less dampening by water vapor?

Bom vídeo, e bom experimento. Parabéns! Rio de Janeiro Brasil.

I think I learned more about chemistry in this comment section than I did at school.

Probably a fair amount of chlorine in the gas as well, so your bubbler is making hydrochloric acid.

Which liquid do you drop at the edge of te blades before blunting them?

خیلی ساده و پرکاربردند،عـــــــــــالــــیترین ویدئوهای آموزشی👍👍👍👍👍

This is not a safe setup. It generates hydrogen & oxygen together. In the wrong concentration hydrogen & oxygen together is extremely explosive. Fair enough if you want to generate hydrogen, but you need to do it with an apparatus that separates the hydrogen & oxygen. Mixing the two is stupid in the extreme...

And some salt *HOLDS UP A WHOLE FUCKING JAR OF SALT*

....se tutto ciò è frutto di studi e preparazione autodidatta ...è veramente fantastico...altro che MCGIVER...Bravissimo .complimenti...

Roman, consider making a play list for the great music you play in your videos. It would be good exposure for the artists.

Next episode: How to cook Meth / Tutorial

*watches entire video even though I'll never make this

Really good. One thing though, if you use two double sided combs with the same size teeth that you cut down instead of the ruler, it's a lot easier. I'm still trying to find a blood extraction kit that doesn't cost $20. Any thoughts?

very nice, I also enjoyed the music too. Better then most music I run in to on youtube.

RUSSIAN razorblades! All other razors won't work! xD Oh man, where did you get them?)) But a very good video, greetings from Russia :-)

this is not safe as it also produces chlorine from the salt

love all your videos I'm going to try to make one my version from your plans thanks a lot for the video keep it up bud

I made something similar back in 2009-early 2010 for a junior high science project, the thing is that back in the day info about hydrogen plants, energy and generators was scarce, you can do the exact same thing with a plastic mayonnaise jar and cap instead of a glass and metal one (it's cheaper and decays slower), as a source of electrolysis I plugged a car battery into two graphite rods (carbon bars are better but also more expensive), in the case of the sealant I noticed that hot glue, wood glue and other silicone materials decay a lot faster (especially because of the salt), so my dad suggested a stronger compound that resist oxidation and exposure to salt, so we ended up using "scuba goo" a compound that resist salt, water, oxidation, pressure and even hydrocarbons like gasoline. in case you're wondering what we used as a pipe to acumulate the gas, we used a small cooper gas tubbing.

we need to hang out bro

correct me if im wrong but ist this not pure hydrogen?

hello and congratulations for the video ... very interesting! I have a question for you ... why you enter the tube (hydrogen + oxygen) in the second container that contains water ?? what good is this extra step? Thank you for your answer ;)

I come here to listen to the music. Oh, and the projects are cool too!

Lemme just whip my IV set out real quick

I only clicked here because I wanted to know, is this a generator, powered by hydrogen, or a generator OF hydrogen.

How long can you expect to use it?? Constant use and shorter sessions!?

Thanks Excelente muy muy Fácil de duplicar. éxito en tu canal .Insuperable.

Aaaaand then he slices his arm in 3

where to get glass jar anyone can tell plz i am not getting where i live

Muito bom,, parabéns bem explicado!!

Does the hypodermic IV needle have something to prevent the hydrogen from burning back into the line or does the constant outflow keep it from burning back into the line/bottle Just curious, id like to build one but don't want to risk making a really loud "bomb"

I have some questions: Why did he run the gas through water? The gas is oxygen and hydrogen or just hydrogen?

很捧的想法！不过从点燃气体的火焰颜色来看，那不是纯氢气！纯氢点燃应该是蓝色火焰，温度2800度以上，视频火焰是黄色的，气体中应该含有大量钠元素！这哥们水中加入的是盐，正确姿势应该加入氢氧化钠或氢氧化钾！这样氢气才会被电解出来！加入盐的话电解会产生氯气（有毒），看下面留言内容，有些老外讨论用交流代替直流能不能行？好多人回答必须用直流！其实我觉的我们不用将氢氧分开输岀，所以交流电应该效果更好！第二个瓶子的作用：观察出气量大小丶过滤气体丶防止点燃回火！另外氢气和空气混合点燃会爆炸，尽量将其燃烧，不要直接排入室内，或戸外进行！

what is that paste that you had used while soldering pls say the name of it

Using graphite is a much better option that razor blades and likely cheaper if yo know how to split pencils. Set in a nice group with epoxy or locktite vertically and wired at the top would make more hydrogen too.

Thats´s fucking amazing :D Thumbs up, Roman :) You are awesome mate :D

whats the name of the first song? i want to know. I like it

Great video! Thank you!

may i ask, you don't need a flashback arrestor with this setup? or if I'm not mistaken, the bubbler serves as arrestor itself? please enlighten me.regards and good work.

DIY hydrogen at home. Sealed with hot glue. What could possibly go wrong...

I give you a big like even I really dont understand how this works.

been diddlin with HHO for some time, just curious, why razor blades and no washers ? also- do you have a vid for a 'dry cell' ?

Very impressive and thanks so much for this... Think I am gonna try it on my ATV to power it instead of using GAS

Next video how to make a hydrogen bomb

noone will ever cut his fingers in redoing that.

the razors as you connect them, behaves like a pF/ tens of pF capacitor in open air ;). with a coil, a big wire antenna and a diode one can obtain a small radio. :)

Is this cost effective or not? since you need a power source to start, I am not sure if the heat generated with this thing will be better than just use the battery power.

Thats actually not a Hydrogen generator, it generates only Hydroxy (a mixture Hydrogen-Oxygen)

I think it needs a little more hot glue ... -.-

Cool video, I'd like to point out the second bottle is important for safety. Without it a flame could flashback into the actual generator and explode.

could you have used a fine comb as a spacer for the blades in the early part of the video rather than a ruler?

now make a rocket to the moon

whats the song @ 1:19???

Nice vid dudde, what did you use as a power supply??how many volts?

Thanks for the video it's interesting.I'm just wondering if anyone know to produce hydrogen gas using this or similar method on a large scale production is worth the amount of gas produced, compared to the amount of energy used to produce it.

i keep wondering, did you hurt your finger during in anyway during the making of this?? XD

use solar power source and ya got something here.

What would you be able to use for the power supply? Like a regulated power supply from a computer or whatever? Or?

Классный "бульбулятор" собрал. Жаль, когда служил, не было "подручного" инструмента для такой штуки. Делали из 2-х лезвий, а иногда даже из алюминиевых ложек/вилок. В последнем исполнении была проблема в поиске проводов алюминиевых. Но работало "на ура" 2 провода в розетку и через 30-60 секунд кипяток.

THIS IS NOT HYDROGEN IT IS HHO hydrogen by itself explodes

Or you can just buy a can of propane from walmart for 2 dollars. And have a more controlled, safer, hotter, more portable, useful torch.

very nice ,simple very good thanks

Good project. I use soda for this. The minus is that when I shut down power supply, sometimes fire goes in bottle and bang happens)) make with plastic bottle it is safer if something will happen. Do you know how to avoid explosions in plastic bottle? I think to add one hole in bottle that closes and opens. When I will finish my work, I will just open it and air will go inside bottle what will itself shut down fire... What do you think?

Made one of these for my highschool science fair about six years ago. It worked, yes. However my principle wasn't too fond of the idea of having a hydrogen bomb in his cafeteria.......I was almost expelled to say the least >.< I made another one for a county fair demonstration two years ago. At the end, I explained why you shouldn't make one and engaged a pre-created short in the system and it exploded violently enough that the metal shed it was in exploded and the windows on a minivan 100ft away shattered. Don't make one unless you want to die or know EXACTLY what you're doing.

where do i get those stolen hospital stuff??

I have a question and would be glad if someone answers or guides me. i was looking at this project and wanted to make one to be used in some of my projects. Will the hydrogen not backfire in to the container exploding it?

you only need voltage on the outer 2 blades, the rest get voltage thru the salt water. go ahead, pull the wires off the middle ones, then power em up while in the water and test the voltage.

Why did you use the second bottle? To cool it down or to purify it?

Were tf do you get all these sirings from

So cool and useful. thx bro.

Made one of these about 5 years ago! Should have filmed it and made a fortune in YT

How to slash your wrists multiple ways 4:00

ممتاز

a question? What happens if we put a load higher than 12 volts or more

instead of ruler you can use two identical plastic combs. It will allow equally space razors at no time.
