We hooked up the bladder to a stove to melt honeycomb; although the weight helped pressurize the system, the rods on the corners were too thick, prohibiting the bag from sliding naturally; someone had to manually push the frame down every few minutes. The honeycomb melted quickly and started to boil in close to an hour's time. However, we know the bag can last for a long time. 

The adjustments for further tests;

• Reduce the diameter of the rods

• Test how far the gas can be from the stove and the side effects.

• Test exactly how long the bag can last with one with the cooker on vs two.
