This is what happens when you burn flour

Dr Graham Walker burning flour
At tonight's Canberra launch of National Science Week, Dr Graham Walker demonstrated what happens when you apply a kitchen blow torch to flour being sprayed in the air.

At the request of the gleeful audience, Dr Walker also showed what happens when you throw a keg's worth of liquid nitrogen into the Shine Dome moat.  Awesome stuff!
