Sae,
Stats 101 was taught to me and they used marshmallows vs. rocks to describe sample variation as well as what could cause variation from other sources so I used it too; jello works also
. If you think to the molecular level, everything is composed more of space than of substance and, unless the temperature is zero Kelvin, everything is jiggling around. Metal oxides form at a certain rate so that would cause a difference in weight. Moisture is either being released or absorbed by the handle so that would also cause a difference in weight. Am I splitting hairs? yeah, sorta, but I have done a bunch of measuring and statistical analysis and have been surprised at how much the sample actually changes. We can eliminate sources of variation using statistical analysis methods. My opinion of how static reality is has been greatly affected.
