A pivoted clear plastic assembly which students use to find the centre of pressure of a totally or partially submerged plane surface. Compact, self-contained and excellent for classroom demonstrations.

A bench mounting apparatus to determine the stability of a pontoon with its centre of gravity metacentric height and metacentre at various heights.

Self contained mobile unit for many experiments in fluid mechanics. Amongst other experiments it covers: properties of fluids, hydrostatic principles and buoyancy / floatation and Archimedes' principle.

Searle's torsion balance with scale and pointer for the determination of the surface tension of liquids.

Bench-mouted apparatus to establish the specific gravity of a liquid when compared with water.

A Bourdon pressure gauge with visible working mechanism to demonstrate how this type of pressure gauge works and how to calibrate it.

Self standing simple falling sphere viscometer, that demonstrates the drag coefficient of different sized particles (spheres) and the viscosity of liquids.

The half-circle and Vee Chine pontoons are an optional extra for the Metacentric Height and Stability experiment that allow the student to compare the stability of different hulls.
