 Again, when you crack that valve on that can, you have no clue what's coming out. Is it an ounce a minute? Is it an ounce five minutes? Is it an ounce in ten seconds? I mean, you just don't know what's coming into the system. And it also depends on which side of your system you're charging it from. You hook that can up to the high side, you actually can blow the can up in your hand. And I have actually seen that happen. I remember a day, I was working at Farmer Heights.
