To show that water has a maximum density at 4 degrees Celsius..
Consists of a sheet metal cylinder with two tubes in the upper and lower regions for inserting thermometers through rubber stoppers. Mounted on a base and encircled midway by an outer trough for holding a mixture of ice and salt. Temperature of the water is measured at the top and bottom of the inner cylindrical vessel over a period as the water-cools.

Induction Coil (Ruhmkorff Coil ) for Physics Lab - The primaries are wound with thicker copper enamelled covered wire on letherite pipe in two layers. The secondary coils are divided into two parts & are given heavy insulation. Each layer is wound in a cover of butter paper & are completing the winding, the entire is dipped into hot wax to seal each layer against moisture effect. The coils are housed in a teakwood base, voltage tested condensers are fitted inside the wooden polished base. Handles to get the spark are fitted on it & make or break points are of silver. One point is adjustable to get any cycle. On/off reversing switch commutator working on 6 to 12 V DC. Size - 10 mm, 25 mm, 50 mm, 75 mm, 100 mm
