I need to find a good science fair and need an idea what i should do. I don't want you to like give it to me, just give me ideas on what i can experiment with. I am in high school so I don't want any stupid ones or too easy ones. Thank you for feedback. I am leaning towards microbiology or engineering, but anything works. I am not stupid, and this science fair is not required, but i just need a little boost on what I should start on. Thanks.
