'''Aerosol''' propellants come in cans, you can buy them at any grocery or department store, and they do not need any auxillary hardware (like a [[fuel meter]]) to use. As such, they are quite popular.

It is recommended that you avoid using hairspray, as it will leave an undesirable residue in the combustion chamber. Deoderant is much better - "Right Guard" in the brown can was the generally recommended aerosol fuel until recently, when the formula was changed to use a non-combustible propellant. Any spray with flammable propellants will work, look for compounds such as [[propane]], [[butane]], isobutane and/or [[starter fluid|ether]]).

Because the amount of fuel cannot be measured accurately (the usual procedure is timing the spray duration by feel), it does not yield the performance that [[fuel meter|metered propane]] does - the pressure generated during a [[closed chamber]] firing is estimated to about 30-40 [[psi]], as compared to 40-50.

If your cannon is not firing, or is firing weakly and you have a flammable fuel (verified by spraying over a flame): check the [[ignition source]]. If you are getting a spark, you are most likely spraying too much fuel in; experiment with varying amounts of fuel until successful results are achieved.  And always remember to [[venting|vent]] the combustion chamber between successful and unsuccessful ignitions.
