Ok, so i am thinking of building a flamethrower, not exguast like the other thread but similar at the back of my buggy. I am a little bit worried that a fuel source such as a deodorant (probably Ax) might explode when the fuel reaches the nozzle (the opening for fuel expulsion). Would you say that is a valid concern or is the opening small enough not to let oxygen go through and not combust the insides of the can?
This question is for everyone who has ever tried making the deodorant flamethrowers! This is a fragile subject since it can cause a lot of property damage

. How would I secure the flame???
