 ==== Test Balloons ====
-The 36” Qualatex balloons to be used have a mass of 37g and have a measured volume of approx. 0.10 (measured by helium lift) to 0.11cu m (measured by water fill) when nicely "full" (i.e. not stretched).  Two balloons have been pressure tested - the first with a manometer the second with a pressure sensor MPX5010.  The results were burst at about 4.7Kpa (0.7PSI) and 5.4Kpa (0.8PSI) respectively.
