So we did it..
It worked! So we put the steel wool in the test tube and waited 3 days. This is the last day! We expected the water to go up in the 3 little measuring cups and we had the 3 test tubes to put the wool in, while the tubes were upside down for the water to go up! The wool rusted each day more and more. It turned into a black and brown mess! So the water is still rising surprisingly. Our hypothesis was correct from the water rising. So we expected the wool to rust (which it did) and we got rusted wool.
