Bubbles are easier than smoke

Waited in all day to get boiler fixed so I could wash without the aid of a kettle! Decided to have a go at taking a pic of smoke (however I don't have a flashgun or lighting or anything else recommended).
Got the joss sticks out (thank you mum for bringing me some back from the Far East, the last time I had joss sticks was at the one year I lasted at uni) and promptly made the house smell like student digs.
Photographing smoke is a lot harder than the bubbles were (and they were challenging) and all my efforts are, quite frankly, pants!
So here is a match!
