Its the same with propane a bucketful of the stuff wont burn if you throw a lit match into it they did it on the training course I did Was it a very cold day? Hmmm I reckon a bucketful of propane at UK room temperature will go up like a good'un but I guess it depends what sort of bucket it is. |

Liquid propane turns to vapour so rapidly in air at atmospheric pressure and at anything above freezing that the gas to oxygen (air) ratio immediately above an open container of liquified gas would be too rich (ie. too much gas) to burn. Petrol, which vapourizes less readily than LPG at lower temperatures, could well attain a combustible mixture ratio immediately above an open container given sufficient air movement (ie. wind/breeze) over the top of the container on a very cold day. From the above, it's a fair assumption that MM used to confine his petrol-bomb manufacturing to the inside of a closed and only slightly draughty shed on warmish days ! |

We used to fill coke cans with petrol and light them then throw them. Quite boring really. It wasn't a real Molotov cocktail to be fair as this was petrol I was authorised to buy and that I had doped with 2 stroke oil. It was for the Evinrude outboard but a friend and I found some external combustion uses for it. We never got round to pure petrol as the main aim was to go out in the boat. |

The gas is heavier than air so it sits in the bucket and excludes oxygen so when the lighted match goes in it just goes out, however if its on the floor its a different kettle of fish altogether |
