---+ Pasadena Unified School District Science Fair We'll have two tables at the PUSD science fair doing science demos for the day. One table will be focused on solar observation and the Sun with an H-alpha solar telescope, a white-light solar telescope, and igniting marshmallows with a parabolic reflector. The other table will be focused on "building a comet" using dry ice and other household materials.
