Flying teabag

I think the 'flying teabag' would make a great name for a boat. (or an aeroplane, come to think of it). 

Anyway, this demo is about neither of these things, but is a neat demo of how to set up a convection current, with the heat from the burning teabag providing enough energy to set up a little thermal convection, which lifts the last, nearly-burnt pieces of teabag high into the air. 

These pieces then settle on Mr Bell's nice clean *cough* lab coat, and startle him, causing him to let out a little involuntary yelp of surprise, which is frankly a little un-manly, even for him. 

Skip to about 1:40 if you don't want any preamble. Otherwise, enjoy!
