Steve any ideas where I can get Napalm? I've not seen it in any supermarkets. I'll try the Hardware shops this weekend.
Sodium Chlorate weedkiller is a pretty effective "propellant" when mixed with sugar.
Now clearly I don't want to be prosecuted here for encouraging the missuse of gardening products, but surely we all had a good old play with this stuff when we were kids? Who could forget the joy of bending over the end of a steel pipe, packing it with the compound, hammering over the other end and chucking it onto a bonfire. Then running away like fu ck before the hiroshima style mushroom cloud and ashy fallout rained down on your bonce!
Those were the days before PC ruinned our lives.
I don't know if you can still get SoCh4(or is that salt?) but I'm fairly sure I saw it in a garden centre last week at £3.99 for a liter tub. Don't buy any let alone take it to LM.
