I LOVE those Thai whirlygig rockets! The happily anarchic atmosphere, the occasional explosions and the spectators running for cover, along with the dense clouds of white smoke put me in mind of my and my brother's experiments in the garden with various kinds of tight containers and mixtures of sugar and sodium chlorate weedkiller! I could never understand why my Dad didn't notice that the weedkiller was disappearing or my Mum, the sugar being used up rather fast.
Our problem was always in creating a satisfactory ignition system, but our greatest success was a Maxwell House coffee jar lid, which we launched a good 100 feet into the air with a loud bang.
