Ban em!
Displays only. The public use stuff is pathetic. Go to a proper display imo. Cheaper, less irritating to neighbours. Safer. And you get a better experience.
Agreed,but that said when I was younger and more foolish we had a hell of a laugh with a jape me and my mates did. we where in a cow field armed with bangers called booms which where lather large ( and because of that to the best of my memory where subsequently banned) There was four of us that came across a freshly deposited cow pat which was still steaming

me and my mate held down another of the gang face down with his arms and legs spread out whist the other of the team inserted three of the fore mentioned bangers into the cow pooh he lit the fuses and we held the victim until the last second when we "legged it"

however the the poor guy did not have the time to stand up and run from the area that would be covered by dispersed cow pooh

It was like a morter shell on the battle of the Somme it went every where, and he was covered in cow sh*t. That said he took in good heart and is still a good mate
