After collecting the elements, you may like to display them. There are several ways to do this. For very small element samples, taping the samples to a large paper periodic table is good. You may also purchase vials in which you place your element samples. This is a more expensive way. For the metals, I place them in a plastic bag. For the powdered metals, powdered semimetals, and nonmetals, I wrap them with tape. You may have a method that works better. If so, I would like to hear about it.
