compare a name brand to a generic brand. do they last all day? same ingredients? etc.

anyways...try which foundation last the longest, or which mascara has the least clumpage and why(i.e the brush type)
The effect of various substances when you drink them, huff the fumes, or smoke them.
There's been one done with Arbonne's anti-aging line. They have the before and after pics posted on the website.
my friend once did natural vs supermarket creams in skin care. she got a group of friends (including me) and asked us to each try a skin care routine for awhile. Some being home remidies, tea tree oil face washes or some products like clean and clear or neutrogena.


she then rated them.


You would have to have a few products tested and make sure you do it for over a period of weeks other wise you wont see the full result of the creams


Also, it may be too easy for 10th grade my friend did it when she was younger, but thats all i could think of to do with makeup/cosmetics.
you should compare a knock off brand of some kind of skin care product compared to the real thing, and see if one really is better
