Hers's a conundrum for you...

You have a round cake with 7 (trick) candles on it. Your mission, should you choose to accept it, is to blow out ALL the candles in as few "blows" as possible!!

Sound simple? Well there are a few rules that you have to abide by (isnt there always??)

1. You start off with all candles lit
2. You can only blow out 1 candle at a time.
3. When you blow on a candle, the 2 candles on either side also change status
- If they are all lit, they all go out
- if they are all out, they all light up
- those lit go out, those out get lit
