Transparent Sandbox

The sandbox is of internal dimensions, (length x width x height) 1.48 m x 0.78 m x 0.645 m, respectively. Transparent barriers have been placed at the two opposite larger sides of the box, in order to better observe the experimental procedure. These barriers are a combination of Plexiglas and glass. Plexiglas has been placed at the external side so that rigidity and durability are achieved, whereas glass has been put at the internal side, in order to minimize friction and simultaneously avoid scratching the Plexiglas.
