dry ice 'explosions'?
When I read of these 'explosions' at LAX caused by dry ice, is this simply a case of the vapor expanding to a volume the soda container can't cope with? (like overfilling a balloon?)....
yeah, dry ice is solid carbon dioxide which warms, turns into gas, that expands inside a sealed container. the container can only withstand so much pressure then explodes. usually a plastic bottle with 1/3 water and dry ice chunks put inside and sealed tightly.
We make these every year at 4th of July..
Take a 2 liter bottle, break up some dry-ice and put it in said bottle (about a half-a-cup works), then pour some water in - about 2 cups - then QUICKLY cap the bottle (screw top) and RUN AWAY. They blow in a couple of minutes - but occasionally the blow VERY quickly. Big BOOOM. No fiery explosions.. Good times to be had by all..
But the physics works the way you described. The CO2 expands and pushes out on the walls of the bottle until the bottle can no longer maintain the volume of the rapidly expanding gas.
What is my joy if all hands, even the unclean, can reach into it? What is my wisdom, if even the fools can dictate to me? What is my freedom, if all creatures, even the botched and impotent, are my masters? What is my life, if I am but to bow, to agree and to obey?

Loud as hell with great force. 2 liter bottles are the best.
can take a while for it to burst, so don't go walking up to it thinking it won't blow. If you want it to blow before it does it on its own, just shoot it w a BB gun.

There was a Mythbusters episode where they covered this.
A little bit of a solid turned into a very large amount of gas.
