You can open and point the bottle rite at the flame from a cutting torch and noting would happen, xcept maybe blow it out if you got close enough. There is no way it can get mixed evenly in the correct ratio with gasoline on the gound to help it ignite. That is why you will see some nozzle designs that make more power with the same jet sizes cause they atomize the fuel better.
The only danger you should think about is what would happen if the burst disk failed to releive presure. The bottle would exlplode, the same way it would if you filled it up with 5000lbs of compressed air(if that even that would pop it). Prety sure all bottles have a burst disk in em, blow down tube only directs the force and N2O outside of the car when it goes.

You should really be worried about the bottle acting like a rocket...... It would probably explose just because if you heated it up its going to build pressure and then explode

Every nitrous bottle has a disc that's designed to give way in the event that bottle pressure rises too much. This isn't something optional that comes with the vent tube. The optional vent tube mounts OVER the existing disc and just vents the nitrous outside the car in the event of a rupture.
As already mentioned, if you are that concerned about the safety of a nitrous system don't use one. Just don't do something stupid like try to re-engineer the kit, which can cause it to malfunction.
There was a big story a while back about a guy with a squeezed Integra who blew the back half of his car off and took out a portion of his garage due to a nitrous bottle explosion. The guy had the N.E. bottle heater that monitors bottle pressure and adjusts the heater to maintain a set pressure. The pressure sensor is mounted after the valve bottle, and the guy kept leaving his heater on after closing the bottle valve. This had the effect of running the heater wide open trying to bring the bottle up to the pressure setting, but this pressure couldn't be measured by the system because the valve was closed. The guy kept blowing safety pressure discs and got fed up with replacing them, so he eventually added something like three more discs stacked on top of each other bringing the blowoff pressure up to 4-5x where it should have been. The pressure was finally enough to exceed the capacity of the bottle, and turned it into a "bomb" which exploded and caused a lot of damage.
It's stories like this that get spread around and give nitrous a bad name. It wasn't the nitrous system's fault that the owner of the car was a dumbass!
Here's some additional information from the Holley N.O.S. website:

Q: How does nitrous work?
A: Nitrous oxide is made up of 2 parts nitrogen and one part oxygen (36% oxygen by weight). During the combustion process in an engine, at about 572 degrees F, nitrous breaks down and releases oxygen. This extra oxygen creates additional power by allowing more fuel to be burned. Nitrogen acts to buffer, or dampen the increased cylinder pressures helping to control the combustion process. Nitrous also has a tremendous "intercooling" effect by reducing intake charge temperatures by 60 to 75 degrees F.

Q: Is nitrous oxide flammable?
A: No. Nitrous Oxide by itself is non-flammable. However, the oxygen present in nitrous oxide causes combustion of fuel to take place more rapidly.

i play with the nitrous because i know nothing will happen and everyone for some reason thinks it is flamible. so i play on their ignorance and scare the **** out of them.

It will not be be flamable itself but with a source of fuel it will accelerate it. It will keep the firing going hardcore if it's lit(fuel) and the the n20 is supplying the air. It'll accelerate the fire kinda like a cutting torch. You guys are so wrong. If it freezes everything and blows out the flame how would your cylinders in your car combust. Wouldn't they freeze and crack your piston?

This should help.

This is assuming of course you don't have a blow down tube. I could be way off with this since I am new to the nitrous scene. Just wondering, Fire would cause the gas inside the bottle to expand till it had now where else to go and if there is no relief valve then that bottle would have to blow right???
