Science Sunday - A Coffee Bean

This is a simple experiment that was initiated by Austyn. He noticed that a coffee bean floats when he puts it in water. He asked me if it will continue to float if he leaves it there overnight. So I told him to leave and and let's see what happens. The next morning we saw that it wasn't floating anymore and it had started to discolour the water. We discussed what may have happened to cause this outcome.
