Sure, as with many of the experiments that we do at science centers.
There just isn't enough time to write the entire script and operational procedures for someone's question. I briefly listed a few experiments to answer the person's question about what types of demos to do. I made sure to emphasize the distance and safety buzzwords. Many of the other people who replied that they do this demo emphasized those as well (Kudos Max Sharfenberger and Michelle Nichols).
For more information on how to do this demo, or the others that I listed, which also have potential dangers and operational issues, I also made sure to provide my contact information on the original email for more one-on-one directions. In fact, many of the answers provided to the questions on this listserv are also brief and I would imagine that any of the answerers would be more than willing to be contacted for add'l info. I know that I have contacted folks (Max - I owe you at least 2 or 3 drinks!), and been contacted, to get more details many times.
Sincerely,
Martin

I love a good kaboom as much as the next guy (ok, more than the next guy),
but I must ask: isn't the demo below pushing the envelope of safety?

3) A little liquid N2 poured into a small plastic container, screw-on the
cap, toss it into a strong metal bin filled w/ water. The nitrogen changes
into a gas, pressure increases and the bottle will explode. Move way and
make sure that you're not near the audience. Small bottles (shampoo bottles
from hotels) work well. The bigger the bottle (soda bottles), the bigger the
explosion and the danger. Wear gloves, goggles and ear muffs.
