Back in the dark ages, when I was in school, we used human hair to construct a hygrometer for measuring the humidity in the air. Since hair counts as "human tissue", many schools are not able to make hair hygrometers, but you can build a nice hygrometer using a pinecone instead of a hair.
The idea for this experiment comes from my wife, Nancy. I was sitting here at the computer, trying to decide what to write about when Nancy made a comment about how good the flowers on the table smelled. Nancy loves flowers, and always has lots of them around the house. That one whiff and this activity practically wrote itself.
