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.

For a vast range of demonstrations and experiments. Includes density, specific gravity, Pascal's law and Archimedes law buoyancy and stability, pressure measurement and much more. Mobile, self-contained and cost-effective.

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

Hares tube to establish the specific gravity of a liquid when compared with water.

A bench mounting apparatus for calibrating Bourdon type pressure gauges using deadweight techniques.

Shows 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 (H2 MKII) that allow the student to compare the stability of different hulls.
