This is a typical introductory experiment to the topic of hygiene, as well as to the topics of solutions and emulsions. The experiment itself can deal only superficially with the topic in question. The teacher will have to provide more detailed information depending on the age group of the students. The materials supplied allow eight groups of students to conduct the experiments simultaneously.

The experiment comprises two subexperiments:
• What happens when you wash your hands?
• The pH value of skin

Notes:
• Observe the safety information in the instructions as well as the applicable safety guidelines for your school.
• All materials mentioned in the instructions will have to be purchased directly from commercial sources.
