Inflated Steel


Inflated steel things, having a go at the Elizabeth Brim method.

And inflated with compressed air. This was abut 1 bar.

Obviously, it can be dangerous to put high-pressure air into a thin red-hot steel container. Especially when it's as badly welded as this one was. Please take all the appropriate precautions
