Spectral Challenge ideas
This wiki page will collect great ideas that have been expressed on the mailing lists or in person at barnraisings that could inspire a Spectral Challenge entry:
- can i do my own soil testing? Usually i send away for a mineral profile.
- how can i know what is being released in a smokestack plume?
- can i tell how much (and of what kind of) smog is in the atmosphere over a city?
- is this gunky stuff in the soil / on the beach just mud or is it a petrochemical?
- add your own here!
