Spooky pumpkin

This photo was sent in by Allan Van Brunschot from Kitchener-Waterloo C & VS, Kitchener. The Halloween demo is simple fog production. Hot water in a beaker is placed into a foam pumpkin and then dry ice is added. Cooled water vapour in the air condenses into tiny water droplets visualized as fog.
