CHOKING HAZARD — small parts not for children under 3 years.
One of the ways geodes form is by gas bubbles escaping from volcanic rock. Over millions of years, minerals seep in and crystals start to form inside. Our kit includes 20 geodes that you can crack open to reveal crystal formations that might include quartz, calcite, or even amethyst. Take a whack and see what you discover! Includes safety goggles and an activity booklet. A household hammer is required.
