Briefly describe how to anneal copper tubing

Great question! Are you useing copper frige tubing if so>

Explanation:

if you are makeing a heater for a fire you are on the right path. Just slowly undo the tubbing. It hint here is slow. I have sometimes used a heat gun to slowly get it apart. Just heat it till in is soft enought to get un done. Then you can use it on a fire to heat water or what ever else you had in mind.
