How do I open large geodes?
Caution: Always wear eye protection when working with geodes. Check your geode for any hairline cracks. If you find one, take a flat tipped screwdriver or a small chisel (depending on the size of the geode) and carefully insert it into the crack. Twist the screwdriver/chisel tip and try to get the geode to separate, if it does not separate then try tapping the screwdriver/chisel lightly with a hammer or the palm of your hand, moving the screwdriver along the crack and hopefully it will open into two nice fitting pieces. Many of the Keokuk geodes will be hollow so you must use care when opening to avoid smashing the geode into numerous pieces. Pick up your geode and if it feels light for it's size it probably has a very thin shell and is mostly hollow ( a baseball size geode will normally weigh about one pound about the weight of a regular can of soup). While wearing gloves to protect your hand, hold the geode in the palm of your hand, strike it lightly with a flat headed hammer (a snap wrist action works best). Continue striking until a crack appears then insert a small screwdriver into the crack and pry open your geode. If 15 strikes of the hammer does not cause a crack increase your striking force a little and continue. If 15 more strikes of the hammer doesn't cause a crack - use the method below. If there is no visible crack in your geode and its weight seems to be appropriate (according to the example above), your geode probably has a small cavity or is mostly solid. Draw a line around the circumference of your geode. Take a chisel and a large hammer and tap along your line until a crack appears, then use the above technique to open it. Another method is to lay the geode in a soft depression on the ground. . Look for any large cracks, hairline cracks or weak spots. When you have decided where you will apply pressure, use a medium weight hammer and center punch. Put the punch in a spot most likely to keep if from sliding off, and hit it several times; easy at first, then harder. If three or four blows do not open the geode, repeat in other spots until a crack does appear. Then use a screwdriver to pry the geode apart. Of course, the easiest method is to put your geode in an old sock and just strike it hard with a good size hammer. Sometimes, if you are lucky, the geode will split right in two but most often it shatters into numerous pieces.

How do I open my Free Geodes?
Caution: Always wear eye protection when working with geodes. Since these geodes are smaller they are almost always hollow. These should open easily by just holding the geode in your hand and tapping it with a small hammer until it cracks open. Then take a small screwdriver and pry it in half. If your geode doesn't open easily, just take a chisel, set the geode on the ground and smack it with a hammer and they will usually split right in two.
