Po was weird. But in water, the number would vary drastically. The mass were the same. Density of object should not have changed. For example - Everett noticed that at the beginning of inserting a mass, the liquid would rise, but fall back down on its own.
Oil is thick and moves slowly.
Water is not. One weird observation. Oil's density seems very low. It seems apparently we got a very, very, very thin liquid. As I did this lab, I can't help but feel I'm missing something.
