How to Tell If A Geode Is Hollow?
In this video, I learn a lot about the density of rocks! Like a lot of people, I adored science at a kid but lost interest over time. This really brought me back to the little science experiments I would do as a kid with my mom’s rickety kitchen scale and, of course, a huge mess that hopefully someone else would clean up.
All you need for this experiment is a kitchen scale and a transparent cup. I used paint measuring cups thinking that the lines would be helpful, but they really weren’t necessary. Any cup that will hold your suspected geode will do!
