is it possible to buy from him his kit ? you can watch him selling those kits to people on youtube
As you know, censorship around the world has been ramping up at an alarming pace. The UK and OFCOM has singled out this community and have been focusing its censorship efforts here. It takes a good amount of resources to maintain the infrastructure for our community and to resist this censorship. We would appreciate any and all donations.
do you think it is possible to contact mr Nitschke via internet ? do you have any instructions or pictures that might help me to build this kit on my own ?
what additional parts we need so that our kit is complete ? is the cylinder from video enough ?
Not impossible but you will most likely fail. I had to go to an industrial place and I paid cash. Told them it was for putting nitrogen into beer. They just want the sale and I didn't act nervous or anything.so even small amount of oxygen makes our purpose impossible ?
Industrial helium can be up to 99,999% pure. Balloon helium is not advised.so even small amount of oxygen makes our purpose impossible ? I read megathread about intert gas and the author recommended that you need 600 litres of gas which means you need pretty big cillinder. I saw cilinders that mr nitschke was selling to people and they looked pretty small . Why nitchke used pretty small canisters with probably pretty small amount of gas inside ?
Nitrogen can be used to brew beer as well. But no, it doesn't have to be 100%. In fact, I have yet to see a cylinder at 100%. I don't think that's even possible. The closest I could find for Argon is 99,9992%.so i should try to buy at welding shops ? for welding there must be 100 percent oxygen free nitrogen or argon. Is that correct ?

how to check if given baloon helium tank is pure helium or not ?Lmao as someone who had 2 tanks in my bedroom to ctb for a few years it made me lol.
There's different cylinders with different volumes. Probably best to look at the volume that youd need.
In contradiction to what a lot of people are saying, there are a lot of balloon helium tanks that are (practically) pure helium which is what you want.
The reason why there should be no oxygen in it when you use an exit bag, you will breathe it in and breath co2 out. Co2 will make you feel like you're suffocating and make your survival instinct kick in.
Also depending on how much oxygen it has, it can make you pass out but miss the bus.
It should say it on the tank/website.how to check if given baloon helium tank is pure helium or not ?
do you think baloon tanks can accomodate 600 litres of gas as we need ?It should say it on the tank/website.
If not, look for a different one. (I used to look at the pictures too which often mentioned it. At least if they dont use outdated pics.)
Don't trust balloon helium unless sold by a company that provides safety papers etc. As a test I bought a small balloon helium tank online. On the site it said 99%, but this is nowhere to be seen on the tank itself.how to check if given baloon helium tank is pure helium or not ?
That's not really the correct way to calculate it. It's simple: multiple the content (l) of a tank with the pressure (bar).A single 23 cm balloon needs 14 liters (0.014 m³) of helium.
For 50 balloons:
Most tanks i've seen are for 50 baloons or less.(there are some larger ones)
- 50 × 14 liters = 700 liters (0.7 m³) of helium
Back in the day i had 2 tanks just to be sure. All it needed was a gas pressure valve with 2 different inputs and 1 output.
i dont know how to do the test. as soon as you put your hand with oxygen meter inside plastic bag full of helium oxygen will get inside so even if 100% helium is inside the tank test results will show oxygenDon't trust balloon helium unless sold by a company that provides safety papers etc. As a test I bought a small balloon helium tank online. On the site it said 99%, but this is nowhere to be seen on the tank itself.
If you want to test it: buy an oxygen meter, fill a plastic bag with helium and check. This is the advice I got from a poster here.
Certainly in the US a lot of balloon helium tanks are mixed with 20% oxygen. The balloon still float, but not as long and they're no use to ctb.
That's not really the correct way to calculate it. It's simple: multiple the content (l) of a tank with the pressure (bar).
A 10 l tank at 200 bar will have 2.000 l of compressed helium/nitrogen.
10 l * 200 bar = 2.000 l (compressed)
For helium a flow of 15 l/min. is needed, so divide 2.000 by 15.
(10 l * 200 bar) / 15 l/min. = 133 minutes
This is the total time the tank will flow at 15 l/min.
It is possible to put the meter in an empty transparent bag and then fill it with Helium. The display could be read through the bag.i dont know how to do the test. as soon as you put your hand with oxygen meter inside plastic bag full of helium oxygen will get inside so even if 100% helium is inside the tank test results will show oxygen
