How To Make A Comet

This is sort of a "trip report" of the 2009 Open House at Indiana University's Physics and Astronomy Dept. It sounds like a fun event, including an instruction on how to make a comet!

In the hands-on astronomy exhibit, my oldest son devoted about ten minutes to making a comet. Ingredients include: water, ammonia, dirt, corn syrup, and dry ice … plus some sarcasm and melodrama. A couple hours later, the comet didn’t look as pretty, but it retained enough mass to make it to our freezer. I fear this may be a summer snow ball accident waiting to happen.

Definitely a fun Fall event for those who can make it next year.
