Good science fair project?

Question

Can people distinguish the difference in brands of soft drinks?

Answer 1

Umm what is the scientific principle or question??

And ... it's been done.

Answer 2

It sounds interesting but how exactly does this pertain to science. .

I guess you can talk about the different ingredients in each soda .. and how that changes taste, if in fact it does...

You'll have to do quite some research in order to make this sound more complicated than it realy is. You dont want to do a project thats too simply or too easy, that usually results in a lower grade..

well good luck :)
