was that bloody drummer! you get the tops taken off a pop bottle so it can't be used as a weapon, yet you can bring a great honking drum in
Shhhhhhhhhhhhh...... you don't want a response like this http://www.barnsleyfc.org.uk/bbs/forums/thread-view.asp?tid=87273&mid=560823#M560823
I don't think it's so much throwing a bottle top I think it's more that you could fill the bottle up, put top back on, and throw it.
if you were really that set on doin that i think you could easily sneak a top in in your pocket its such a rediculus rule
