Algernon said:What's a sparkler?
Clearly not what I thought of at first - I must say I was initially surprised to hear of beer being served with a sparkler - usually they reserve little indoor fireworks for hideous over-priced cocktails on the Costa del Sleaze...

Plastic adapters that fit on the end of a beer tap. They add a bit of head to a pint but many drinkers, myself included, do not like them. They're almost impossible to avoid in Wales and in the North of England, which is kind of odd when you think about it: you're trying to charge a Yorkshireman over £1.50 for a pint which isn't even filled to the top!
