[terraform242]

would benefit from some appropriate music. instrumental, electronic, dreamy.

only 3 words: cool but crap

[RenegadeFury]

Lawl I wasi n that exact same spot your standing

Notice the smaller pieces move faster, that's cause the smaller the object the greater the ratio of surface area per volume, thus more sublimination per mass. You know what I'd like to see is a good video of something at the triple point, and a supercritical fluid.

ok thx for you answers

[reallygonecat]

It looks like little comets

[Grenadierer]

lal this is dry ice ? Looks like natrium or sopmething like that

[jlehtira]

It's already vaporising before hitting the pool. A metal would not do that.

Also, I remember we did an experiment about it at school - Na or K, I don't remember which - and it was FAR mor explosive.

This is also solid to begin with. Looks very much like dry ice to me.

Having built and maintained this exibit I can say with certainty that it is indeed dry ice.  It can be viewed in person at the Exploratorium in San Francisco.

[Mojosam]

Um....having ACTUALLY built this exhibit, I can say that you most certainly didn't. However, it is dry ice and the work can be viewed at the Exploratorium, the Chabot Planetarium, and 8 other science museums around the world.

just say this....freaking amazing.....iam an artist i would love to build a installation incorporating this.

my question is does the dry ice fumes need to vent, also is the dry ice pre crushed into the little pieces?...
