    For reasons, I’ve borne witness to portable propane tanks punctured in high velocity impacts. Sadly, unless there’s an ignition source or substantial friction/heat, the propane will just vaporize into gas and vent away [citation needed]. From what I observed, the tank made a great big impact noise and lots of wooshing, but no flames or explosion.

    We then tried it again with a small tea candle nearby and the results were more spectacular.

      Wouldn’t there be sparks that could cause ignition?

        It’s not quite like that. It’s such high pressure that it needs a strong flame to become lit otherwise the pressure of expansion overwhelms the ignition source. Aka it blows itself out.

        You can make sure there are …
