The term comes from the Latin apportare (to bring). It refers to the sudden appearance of objects in enclosed spaces. There are two forms. The objects disappear as they came, or the objects remain.
Example:
Ex 227 A pastor wrote to me that he had been visited by three spiritists. One of the spiritists held out his open hand to the priest and said, “Now look closely”. At that moment several red gems formed in the open hand of the spiritists. It was not a trick. In other words, the stones did not come out of his sleeve. The spiritist explained, “These are gifts from our friends on the other side. But they will disappear in a few minutes”. The priest watched closely. In three or four minutes the stones disappeared.
