Kid's Astronomy: Planets 2

Creating Saturn's rings and shepherd moons
This was this week's class, the outer solar system.  The original of this class was blogged here, I'm just adding current pictures and noting anything I did differently.

Building the comet

The big thing I did differently was to get extra dry ice (note to self, 5 pounds was plenty).

We put it colored water and chemistry glassware to look like mad scientists.

And we put it into juice for the kids to drink!

I also showed them why proper ventilation is needed.  I lowered a candle into the CO2 filled ice chest, then poured it from one of their bubbling flasks.

A marvelous time was had by all!
