To introduce spark thinking about the processes that go into the formation of different types of rocks. Kinda corny, but good for younger children. Every mineral has a unique crystal form. The shape of the molecules that make up a pure mineral are exactly the same as the visible shape of the crystal after it has grown. Extremely time consuming since it takes days for crystals to grow, but still a cool demo.

Junior High to High School 6. Time consuming and difficult to find a frozen stone in Southern California in the Springtime, but an interesting demo nonetheless.
