After setting up my test, I had had my balloon standing up nicely at mid-afternoon but by the time I left the shop that evening the balloon had collapsed! I left the shop in disgust! To my surprise, when I went out to the shop (an unheated garage) at noon the next day the balloon was again standing at attention! Don't forget in addition to changes in atmospheric pressure, changes in temperature also effects the pressure in the tank. When the shop warmed to the previous day's temperature the balloon had returned to its original size! No leaks......YIPPEE! It followed this pattern for the next several days.
