Creative and unique science fair ideas? ISEF?

I was required to do an ISEF science fair for this summer, and I only have 2 days left. Lmao.

Is there anything I could do that is unique and creative that hasn't been done a million times?

I wanted to program a simple program that could solve a math problem.

But, I'm only a 9th grader with no basic knowledge.

But, I've played a game where a script can control what your control does, like cast magic or attack to kill a monster while you're away.

If not, could I do a " Which product would help protect my skin from UV radiation and my skin cells ? " Tomato Scrub or Egg whites/yolk.
