Although it is true that various pressure and temperature differentials can be recreated in a laboratory, not all laboratories have the necessary
equipment, and not all researchers have access to a laboratory at all times. If this was independent, non-funded research, then it could be that the
researcher was forced to use a balloon by the cost pressures involved with renting lab space.
It could also be that the experiment was designed to be run in as close to actual conditions as physically possible, and that the variables involved
were more than the pressure and temperature of the tested substance or article, but also the actual altitude. Gravity is tricky stuff.
