My students is experimenting on the effect of different kind of milk on the skin... Controlled variables: exposue to sunlight and the food eaten and the age as well...
we have the difficulty on controlling it though...
my students ask me if they can use tomato fruit instead to avoid using animal.
i dont know the answer my self ( i am not hypocrite... ha!ha!ha!). I let them try it though... how would we know if i'll not take the possibility...
what do you think? would it be possible?
