This has definitely been one of the most violent things I've done in a while. It seemed simple enough. Just get some liquid butane into a piece of silicone tubing with some salt and make a safe-ish bubble tube that can be shaped round bends.
The main issue here is that butane is a vapour at room temperature, and to keep it liquid requires a pressure of around 50 PSI.
It follows that the main issue was keeping the end stops in place, especially when trying to put them into a pre-filled tube.
On more than one occasion it let rip explosively and spewed the entire contents of the tube as a highly combustible vapour out in a single blast that hit the other side of the room.
The second version based on a butane filling valve from a lighter was marginally more successful, but the butane still leaked out gradually.
An interesting note is that the silicone tube went hard and reduced in diameter slightly after being exposed to high pressure butane.

Beware of the dangers, of the beautiful things that man creates. They can, quite literally, take your breath away.

As a truly ignorant viewer, hose clamp vs heat shrink?
Diethyl ether might work better. It'll need a little more heat but you can just pour it out of a bottle/can.
Does RoSPA still exist in the UK, or have they just wandered away, blank-eyed and muttering "yeah….whatever….what's the bloody point……." ?

Needed a check valve…
I know this is six years old and BC is still alive, but FUCK ME, the amount of risks he just casually reeled off in the first five minutes alone gave me the sweats.
OH my god this is why i worry about young minds and you tube and tiktok. Love your content I have watched quite few. A fellow did somthing similar making a petrol fuelled gas stove lol he burnt his house down……
More health less safety good man
Schrader Valve…Schrader…Hank Schrader…I have a sudden urge to watch Breaking Bad.
You have a LOT of faith in shrink tubing… 😂🤣
I got here from watching bho extractions. Hmm
Did the pressure hold? I don’t see an update in the description?
