Center of gravity of a freely suspended two-dimensional object always lies along the line drawn vertically downward from its point of suspension. A simple and economical apparatus for demonstration of geometrical center of gravity of two-dimensional objects. Each lamina has suspension holes along their periphery. The point of intersection of lines drawn from point of suspension of 2 or more holes of a lamina gives center of gravity of that 2-dimensional lamina. Comprises a clear perspex rod mounted on a base with a suspension screw at the top and four laminas of clear acrylic 1 each of circular, triangular, square and trapezoidal.

Supersonic flow and the occurring shock waves can be directly observed with the supplied Schlieren optic apparatus. The continuous operation can allow enough time to take measurements and to observe the phenomena. This an open, continuously operating supersonic wind tunnel with a rectangular measuring section. Transonic and supersonic flows from Mach 0.8 up to Mach 1.8 can be realized with interchangeable measuring sections and nozzle profiles. The tunnel is driven by a vacuum pump (included). The pump is effectively silenced so it can be placed in the same room as the wind tunnel. Four aerofoil models are supplied: a wedge, a double wedge, a bullet and a rocket. A flow straightener at the inlet ensures a low degree of turbulence.
