Home made Aspergillus Flavus

The wash basins near the guest room are always washed and sanitized with disinfectants & bleach; it even smells like a medical clinic.

This made them a candidate for my daughter's experiment:

• Placed a petri dish near the wash basin for three hours.
• Closed the dish and sealed it.
• Placed in an incubator for one week.
• Sectioned a part of it, stained, and examined under a microscope.

Due to time constrains, only the green part was examined, and it was a fungus named Aspergillus Flavus.

This has really gotten us thinking, what should one do to keep their homes clean?
