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.
