Flash Point: Perhaps use a walk in freezer where you can vary the temperature and do the flamethrower thing with a lighter and the aerosol.

You'd set up a pressurised capillary for the viscosity and perhaps again at atmospheric pressure but then it's not as interesting.
Flashpoint is not of the gas but of the liquid, pressurised vessel at aerosol pressure with the liquid subcooled and then heated until it flashes off. The experiment would have to be repeated for different pressures.
