I think this is a really good research idea. I think a balloon is not a good idea, car exhaust is hot! [Also, the exhaust pipe isreally hot, you could burn yourself badly by touching it] Could you test particles of different sizes that aren't necessarily pollutants. For example, flour. Charcoal is carbon-could you grind it finely enough? (Check with your folks !before! you grind up charcoal in the blender. ) Don't use the stuff with lighter fluid. These some examples... maybe you can come up with more.sammhy wrote:Hi. I investigated more in aerosols and partculates. I found out that all aerosol both absorb and scatter radiation. There is a Single Scattering Albedo (SSA) that measures the light absorption of light. For example, a major atmospheric abosrber that has a SSA of 0.23 is Black Carbon, which arises from combustion of fossil fuel.
I am wondering if I can probably collect this particulate matter with a baloon from the car exhaustion tube, while the car engine is on. Is this method feasible and safe? I would also like to vary and test some other particulate matters through frequencies of light.
Thank you very much.

Decide what it is you want to test and then think how you could model that.
