SSI-PHY-MESS-54
This model can be plugged into a standard wall outlet to illuminate the sun to effectively demonstrate daylight, night, seasons, and phases of the moon. 6′ Power cord. The sun, earth and moon manually revolve around one another on this gear driven model. If the sun were to be shown
PHY-MESS-55 ALPHA SCATTERING APPARATUS
SSI-PHY-MESS-55
A low cost apparatus for the demonstration of the Rutherford scattering by means of a gravitational analog of inverse square law repulsion. Comprises a wooden launching lamp about 300x50x105mm (LxWxH) with a guiding groove running down its curved front face along its length and index marks at 40,60, 80 and
PHY-MESS-56 SPARK DISCHARGE APPARATUS
SSI-PHY-MESS-56
Demonstrates the ionizing effect of the radioactive emissions. A long narrow metal strip is mounted on edge parallel to and underneath a wire mesh, together form two long conductors with a narrow air gap insulation between them and are provided with a 4mmsocket terminals for power input. On applying high

PHY-MESS-63 GALILEO THERMOMETER
SSI-PHY-MESS-63
The liquid in the glass tube becomes less dense and bulbs sink one by one and when temperature falls the bulbs slowly rise one by one. The lowest floating bulb indicates the actual temperature.
PHY-MESS-64 HARR OR HAIR HYGROMETER
SSI-PHY-MESS-64
A hygrometer that measures relative humidity by means of the variation in length of a strand of human hair. The length variation of a properly treated hair is 2%–2.5% when the humidity changes from 0%–100%. Circular dial type hygrometer with scale 0 to 100×1% RH (Relative Humidity). In metal case
PHY-MESS-65 WHIRLING HYGROMETER
SSI-PHY-MESS-65
The ventilated type of hygrometer gives greater accuracy for humidity demonstrations and is particularly useful for measuring local differences in humidity. There are two thermometers mounted inside a case, fully enclosed to prevent breakage, one dry and other having a wick dipping into a water reservoir at the end of
