Jar (pelike) with Odysseus and Elpenor Jar (pelike) with Odysseus and Elpenor A pelike was a ceramic container that the Greeks used as storage/transportation for wine and olive oil. As seen in the picture on the right, it had a large belly with thin, open handles. Unlike other transportation jars (like the amphora), a pelike would have a flattened bottom so that it could stand on its own. Pelikes often had one large scene across the belly of the jar with minimal distractions around. This would focus the viewers eyes to the center of the pelike which was often a mythological scene of sorts. This red-figure
Leyden jar used in demonstrations. The jar is constructed out of a glass cup nested between two fairly snugly fitting metal cups. When the jar is charged with a high voltage and carefully dismantled, it is discovered that all the parts may be freely handled without discharging the jar. If the pieces are re-assembled, a large spark may still be obtained from it. This demonstration appears to suggest that capacitors store their charge inside their dielectric. This theory was taught throughout the 1800s. However, this phenomenon is a special effect caused by the high voltage on the Leyden jar. In the dissectible
