Re: comet in the classroom: Also, you will notice over an hour or two that the nucleus will fizz and pop as dry ice sublimates and CO2 bubbles break through the comet crust and form small craters. As this continues, the nucleus begins to look very much like the surface of an asteroid. The black dirt gives it the necessary coloring. Otherwise it just becomes another snowball. It's neat for children (or anyone else) to see this nucleus "evolve". Be careful, though when letting your comet out of the bag or it will start to fly around the room in a highly elliptical orbit, using the makers head for the focus. :=)
