Shucks, my brother collected the powder from all the fireworks that didn't go off one Fourth of July in an aluminum bowl. Sitting with his legs splayed out, he accidentally let the end of a "punk" drop into the bowl. Fortunately he only lost his eyebrows and the front part of his hair, but we had to clean up the porch afterwards. I think he was about 10 at the time....

And I can tell you from experience to never, ever, ever mix chlorine bleach and ammonia solution...in a car with the windows rolled up....
