They never saw it coming...

It's not a volcano, it's a limnic eruption, with lots of dead animals below the carbon dioxide emitting crater lake in Africa.

(Year 6 "natural disaster" science project. It looks better in real life as the mist flows down over the huts. Dry ice is fun.)

Actually, I never knew that those cases of deadly lake out-gassing in Africa in the 1980's were called "limnic eruptions". My son found out about them on the net, and it's a more interesting thing to make than a plain volcano. I suspect he'll be the only limnic eruption in class.
