A complete "living" periodic table of samples of all the elements through uranium is described. These sizable (usually many gram) samples are on display at the University of North Texas and are available for study by visitors. This exhibit is also used on tours that I conduct throughout the nation. In many instances a sample of an element is accompanied by a direct commercial application (e.g., space rotors for beryllium, bearings for molybdenum, watches for radium). This periodic table is very helpful in enabling the student to gain a hands-on understanding of the true nature of the elements--as opposed to the more usual compilation of mere abstract data. Each element is also accompanied by specimens of minerals from which it was originally isolated. The mineral has been collected from the original site of discovery if this is known.
