expanding the molecules, huh? Thermal expansion yes, but I thought the purpose of annealing was to recrystallize strained metallic crystals caused by the introduction of dislocations.
Hell if I know. I just watched some guy beat a piece of sheet metal into a tank and this was one of the steps necessary.
Well, let's think about this. You can get a 5 gallon BIB (bag in a box) of soda syrup for about $27 (ypmv). That 5 gallons will yield approx 3800 oz of finished product. So, the answer is, approx 21 oz., but, you can also add approx 20 oz of ice, so, break out that 44oz cup, put some ice in it and fill 'er to the brim!
