      Yes – see the picture on my profile. I’m exploding flour, to demonstrate that there is a lot of energy in food.

      I did some work a long time ago trying to improve the protective clothing for bomb disposal men. For this we needed to make lots of small explosions without using explosives (too dangerous, too expensive and too variable), so we had a explosion simulator using compressed nitrogen.
