Dynamik

Way cool. Many years ago I was involved in assessing the acid that comes out of the exhaust of the space shuttle SRBs. The pH of the exhaust is something akin to battery acid. IIRC it comes from when they flood the launch pad with water so the reflected heat doesn't melt the space shuttle. A lot of the times they abort launch, IIRC are due to potential public exposure to downwind drift of the acid mist.
