CU Wizards to go with the flow

Making a classroom geyser from mints and soda will be among the experiments highlighting the University of Colorado's Dec. 23 CU Wizards show titled "Go With the Flow."

CU-Boulder faculty member Janet deGrazia of the chemical and biological engineering department will present the show at 9:30 a.m. in Cristol Chemistry and Biochemistry room 140 on the Boulder campus.

During the show, deGrazia will explore the properties of fluids. Guests will take part in experiments and learn why soap floats, how to keep the carbonation in soda and how to make "elephant snot."

The CU Wizards series runs from September to June and features presentations on astronomy, chemistry and physics. Though intended primarily for students in grades five through nine, the Saturday shows are educational and entertaining to people of any age.

Doggie Don't

Bacteria, viruses, and parasites! Doggy doo is a definite don't when left in parks, lawns, on trails, sidewalks, and streets. Pet waste carries some pretty ugly stuff that poses a definite health risk to humans and wildlife.

When pet waste is not properly disposed of, it can wash into our lakes and streams where it can become a significant source of water pollution. As pet waste decays in water, it uses oxygen and releases ammonia and releases nutrients that promote weed and algae growth. That can be toxic to fish and other aquatic wildlife.

Pet waste is as natural as the diseases it carries. Don't leave it lying around.
