We had a great night on Saturday with our fireworks.
One particular large, very large,
large rocket blew up on the launch pad rendering me partially blind from the flash for about 5 minutes. 
After the smoke, sparks and the rest of the explosion died down my pal was also floundering around partially deaf and seemingly somewhat incoherent. The blast had blown the out house door in and my pal was in a fit of panic asking if was on fire, but alas, I couldn't see him properly, finding the whole experience quite amusing.
It happened so unbelievably quickly, though after few minutes later we dragged him inside stripping off his melted jacket, and found the explosion to have burnt through his sleeve melting the skin on his forearm as well as creating significant burns all down his chest.
Rather than prizing the moulten plastic jacket off the burns round his neck with a rusty old pair of pliers, we took him to hospital where he was promptly treated.......
It was an experience, and shows the clear dangers of intentionally igniting small explosive devices in your back garden.
The worst part was it really put me off me pie & pea's.....
He's a lucky man, it could have been a lot worse for the pair of us.
