Students pointed out the following 'wish list' in order to demonstrate their professional and behavioral skills in a more efficient way: Laboratories should have all necessary equipment; schools should have a fully-equipped technology room with overhead projector, epidiascope
, computers and data-show, and the walls should be covered with all kinds of diagrams and other physics-related posters; class sizes should not exceed 25-30 students who are smart and willing to learn.
Workmen dismantling a wall in one of the buildings on the Queensgate campus found a display cabinet containing a wind-up gramophone and an epidiascope
, an early type of slide projector.
For young Gwyn: an epidiascope
, a pencil-box with a special hole for the rubber, a hoop and bowlie.
