Used to tape a small medicine bottle full of petrol to a firecracker then attach to model mounted to run down a wire from a height - light wick and let go! Also made flame throwers by filling water pistols with metho - squeeze trigger while holding lit match under muzzle.
Of course there was always sulphur/potassium chlorate mix.
Marvellous how kids 12000 miles apart came up with similar fun ideas.
What do the kids of today do now that none of the above is pc? Shoot up heroin I suppose.
