Which of these science fair projects sounds the best?

Apr 30

My group and I chose this thing about soccer and pressure but I just realized that it was an elementary grade project so I had to change it. I don't know which one of these would be the best.
1. The objective of this project is to use paper chromatography to analyze ink components in permanent black markers.
2. The goal of this project is to investigate how added salt and added detergent affect the surface tension of water.
3. The goal of this project is to build a roller coaster for marbles using Foam Pipe Insulation and to investigate how much height is needed in order for the marble to run through a loop of fixed size.
4. The goal of this project is to create a colorful mini light show and shadow wall to learn about mixing and subtracting the primary colors of visible light.
5. The goal of this project is to use a homemade single-beam balance to directly measure the surface tension of a liquid.
6. How the color of an object affects how much heat it absorbs when exposed to light
I'm in 10th grade in an honors chem class, if that helps anyone.
PS Thanks for helping!

The marble coaster sounds like the most visual, interesting, easiest and most fun to do. At least to me

How to build a roller coaster?

    3 and 4 are my favorites, I actually did a somewhat more advanced version of number 3 in Physics last year, it was alright.
