Help Helium tank nozzle relies on pressing down on it, what do I do?

[sivvie]

So I bought a helium tank (photo for reference) a few weeks ago and I was planning on doing the exit bag method, but I found out only afterwards that I need to hold down the nozzle for helium to come out. The tank is still here and pretty full, but I just wanted to know if there was a way I could keep consistent flow without holding down the nozzle. I also bought an oxygen mask with it and covered my mouth/nose area with a plastic bag. I tried contacting a few sellers who sold gas regulators and they told me they wouldn't work with this type of gas/tank. So what do I do now?

I could do the SN method but I'll have to wait for a few weeks/months till I have enough money for the other meds or drugs. Is the helium tank worth trying again for?

I'm pretty sure there's oxygen in it and it won't work. You would probably find it's a mixture of helium and air on the package, unless it was manufactured a couple years ago.

You could try making a box and putting the whole thing in upside down, the weight of the tank would hold the nozzle and it wouldn't tip over. However helium tanks now contain oxygen to cut costs and prevent deaths with this method.

It says it's 99.9% helium, and i tried inhaling some of it and it made my voice higher. would that still mean there's a possibility of it having too much oxygen?

hmm could you draw a low effort drawing just to demonstrate what you mean? hahah sorry, you don't have to! but i'm just trying to imagine what that would look like

They changed the content to include up to 20% air back in 2015. It's interesting that you could get one with 99.9% helium... The voice change is the property of helium, nothing to do with oxygen.
There's insturction on constructing the flow control in old versions of pph.
