Whole Geode. A geode is a round rock which contains a hollow cavity lined with crystals. It is quite fun to break open a geode and see what the crystal formations look like inside. Children and adults love to open their own geodes. Home school parents, this is a unique science/geology project.
A very simple way to crack a geode is simply to place the geode inside of a sock or fabric bag to contain the soon to be broken pieces.
With the geode in a bag, gently striking the geode with a rock-hammer, sledgehammer, or even a harder rock should facture the geode just enough to crack it open.
