Aerosol can in a fire can be fun...
hmmm, body odour spray is the best, spray perfume stinks too much, bit like the old Brut33...
Paint cans can be fun but place them in hot tube, the correct way up and you get pretty patterns for 10 _+ metres...
Aerostart goes bang, but not as good as body spray...
CRC, WD40, etc, is just a waste...
Never tried a butane can tho... Maybe my son will... oh and half empty to empty is better except full body odour spray...
Do not hang around if you haven't seen the results before, they will send all sorts in all directions, but they wont leave a huge hole in the ground, have to be a fairly large tank for that...
Gas bottles/tanks have burn off(pressure relief) valves, once the heat creates x amount of pressure it releases its contents, this will happen on and off while the heat continues, once the container gets below about 10% it will explode.. The idea is to get the heat down before it loses the contents to the 10% level... Most gas containers only hold 80% content levels...ps, Bulk transport requires a vehicle to load below 20% or above 80%, the same as liquids... That reduces movement and weight transfer... If you see any bulk carriers, ie fuel tankers, gas tankers, cement tankers or agitators, remember they may be in between those points between deliveries, you cut them off, they'll leave a mess...
LPG is liquified under pressure, the bottle standing up is the only way to use as the liquid releases gas to the upper part... If you invert the bottle you will release the liquid, which will expand but not burn til its diluted enough to do so...But inverted, you can fill you smaller bottles, ie from 45kg to 9kg/4kg/0.8kg bottles(there are bottles designed for decanting, they are used upright but no good for connecting to an appliance)... you need a filling kit and I think most states require you to be licensed in some form....
Many years ago, at a place called Sandfire, there was an Oxygen bottle near the bowsers, it had peeled open after falling off a truck(Ithink about 5 fell off), this particular bottle had blown the side out, another the nozzle came off and over took the truck... Pretty volatile is oxygen but not as bad as Hydrogen...
Now onto the butane stoves, I wouldnt leave home with out it, and when I forget to buy lpg for home, its my life saver... I can tell you that a complete stove, with bottle still in and place in the plastic container it came in, does not explode when run over by Roadtrain weighing 96.5 tonne, in fact 11 sets of duals can go over it and it just appears from last axle about 10mm high, no bang... I was following a friend out of a bin and he forgot his stove, well it was a bit of a flat day after that...[happycry]
Sadly they had recalled all the stoves only a day before hand, poor fellow was devastated, so I gave him my backup one... He treasures, but he is on a policy to ensure a photo if he forgets it when driving off...
