I'm thinking about getting confetti for our guests to throw so we can have the 'confetti shot' photos. I remember hearing that you're only allowed to use certain types as some can explode pigeons or something?? any truth in that and what should I avoid? I quite fancy having bubbles, but the guns are too expensiveto buy many and I can probably pinch 2 from my niece and nephew for the day. Would this be too much having both? I just don't want to give the guns to, say, best man and bridesmaid, and not have anything else for anybody else to do/throw x
