When teaching about minerals, there is no way that you can omit the topic of crystals. Usually, we either go to our mineral cases and take out examples of crystals to pass around, or we grow our own. The only problem with these methods is that both take time. With the former, we are looking at crystals "after the fact." With the latter, we lost the interest of some students because it takes too long to grow crystals from a solution.
