OK. I'VE THOUGHT ABOUT IT AGAIN.

OK.. so basically I'm just clarifying what i said before cause yeah, i was a bit confused myself.
SO, I'm gonna use like a piece of cheesecloth or like a coffee filter thing to act as the skin.
Then, I'm gonna like spread a certain amount of moisturiser on top. To compare results, I will, use different brands, and leave one filter bare. i will place the filter on top of a jar of a certain amount of water and I'll make sure the jar of water is sealed tight by the filter so like the water can pass only through the filter. (if you get what i mean cause i seriously can't word it differently D:) I'm gonna like check how much water there is left in the jar every hour or so and record observations ladida.

independent variable: time, weather?
dependent variable: brand of moisturiser
controlled variable: amount of moisturiser used, amount of water in jar, size of jar, filter, place it is set

ALRIGHT. AM I DONE YET?
