I tried water. Bashed the end of the copper closed both ends and filled with water fully. It still kinked. It must have expanded the walls of the copper along its entire length just enough to allow it to kink. I ended up doing salt, it came out eventually.
Freezing sounds worth a go. As long as it doesnt split the walls when your trying to work with it.

Sand/salt will move with the pipe and keep it filled uniformly.

My freezer (my garage or anywhere on my property outside my house) is expected to be well below freezing temps most of the week. I won't have to take my frozen copper tubing out of my freezer to work with it. I won't have to worry about it thawing and going soft. I'll let yawl know how it works.
