I don't know what kind of oil I should use to simulate crude oil. (If I could get crude oil, that would be great, but I wouldn't know where to buy it. Do they sell that stuff to the general public, in small amounts?) Do you have any suggestions on this? Maybe a bi-product of crude oil, that's somewhat similar? It would have to be sold somewhere accessable, and not be too pricey. Would motor oil be a good substitue?
Also, the feathers would be a problem. Where could I get feathers? What kind of bird should they be from, or does it even matter? Is eBay reliable, or would shipping take too long? Also, how much should I spend on feathers?
Finally, the control group. I'm thinking about using warm water and soap to wash the feathers, not just the soap. Does this mean my control group should be washed in just warm water, or stay covered in oil? And should I wash each feather under a certain time limit, or just until I get the feather clean? How much of each kind of soap should I use? And should I use a set amount?
Do you know how I could measure my results? Would it be possible to make a scale, or chart? Or would it just be observations?
Overall, do you think my idea is doable? Would it be a useful project? This is just an idea, after all. I could talk to my teacher and modify it, if you have any suggestions. And sorry for all the questions, but if you could answer them, it would really help me out.
