Too bad she didn't make a dry-ice bomb. I think a lot of states don't categorize it properly as an explosive device because it is caused by a phase-change and not a chemical reaction. Oh and response to the officials that said this: >Their response: kids should learn that "there are consequences to their actions." That is a disingenuous response that could be used for any punishment. Kids can learn about consequences without needing a draconian punishment. No one every suggested not punishing her.

My high school had a dry ice fogger in the theatre department for making the close to the ground fog effect for productions. Basically, it was an 80 gallon drum with a heating element in it, a basket that could be lowered and tubes for the fog to escape. You heated the water, then put the dry ice in the basket, clamped the top down tight, then plunged the dry ice into the water. Makes great fog that is mostly CO2 gas. Well, if you don't clamp the top down tight enough, it'll go flying off, throwing hot water everywhere. This happened during one production and did quite a bit of set damage. Thankfully nobody was scalded badly. Note, don't use this if you're doing a musical with an orchestra, or the fog flowing into the orchestra pit can result in woozy, oxygen deprived musicians.

  Well, it's not out of the question that the pit orchestra might appreciate that effect. What was the necessity of clamping down the top, given that there were open tubes for the fog (and pressure) to escape?

    The gas expansion is extremely fast - you're basically turning a few pounds of dry ice from solid to gas + water vapor in a matter of seconds. With the pressures involved, if the top isn't on securely, shooting the top off is the path of least resistance.

  We used to use a different method of piping standard dog machine fog through ice to make the same effect. Slightly messy but probably without the danger of suffocating people.

Heck, my high school science teacher brought dry ice and a bunch of little plastic bottles to the last-day-of-school party! My dad is the headmaster of a K-8 school (that's 5-13ish years old) and the graduating class bought him a .22 rifle which they presented during graduation in the school building. He said "Well, you can tell this isn't a public school!" :)

"No one every suggested not punishing her." Ok, I suggest not punishing her. Now it's not "no one".

Second. This is not teaching anyone anything or modifying behavior constructively. This is destroying her life.
