What have I learned??

I now have 3 1/2 weeks of school behind me now and I have learned a lot! Most recently I learned that you can boil water if you drop the pressure around it enough. Sounds simple since I live at 5,400' and water for me boils at 205 degrees F. But If you lower the pressure enough you can get it to boil at 40 degrees F. The water will still be cold to the touch but it will boil or turn into the next state, vapor (steam). Cool 'eh!

Also I started brazing in one of my classes and here is some of my work. I swaged a few pieces of 3/8" copper tube and then brazed them together. Remember this is the first time I have ever used a torch.
