    Stirling Engine, Low Temperature

    An affordable Stirling engine which works at very low temperature differences. A cup of warm water (must be at least 60 °C) can make the motor run, which means that water heated by sunlight can become hot enough to drive this motor. Like other Stirling engines, this type works by converting temperature differences into mechanical energy as warm air expands and cold air contracts. This is utilized in closed system where the same air is pumped back and forth between cold and hot engine part. Illustrates perfectly how Stirling engines operate and can be used with many different heat sources. Weight: 330 g. Dimensions (H x W x D): 144 x 90 x 90 mm.

    Rijke Tube (Singing Pipe)

    The 'Singing Pipe' apparatus is a simple, effective and entertaining way to demonstrate energy conversion from heat (thermal energy) to sound energy. Quick and easy to set up and use, this demonstration rarely fails to impress. The apparatus consists of a 450 x 28 mm copper tube which has a metal gauze fitted inside, at pinch point part way up from the base. The tube should be supported by a retort clamp towards the top, away from the heat, and blue Bunsen burner flame directed into the base and onto the gauze for few seconds only. Shortly after removing the flame, the tube emits loud 'foghorn' sound as air is drawn up the tube by heat rising from the hot gauze. If the tube becomes too hot it will stop emitting sound, in which case it should be allowed to cool before trying again.

    Wood/Metal Cylinder

    The wood/metal cylinder offers a nice demonstration of conduction and insulation. The apparatus consists of a copper tube attached to a wooden rod of equal diameter. A piece of paper is wrapped tightly around the central section, covering the wood and metal parts, then the rod/cylinder is passed through a Bunsen burner flame for few seconds, making sure both wood and metal parts pass through the flame. The metal part conducts heat away so the paper hardly browns, but because the wood part is an insulator the paper covering gets scorched by the flame. Dimensions (L x Dia.): 190 x 22 mm.

    Ice Melting Kit, Advanced

    This advanced ice melting kit nicely demonstrates the thermal conductivity of materials by using different types of metal blocks to melt ice cubes. The kit consists of an acrylic base with sump, an acrylic tube, two cylindrical copper blocks and two cylindrical steel blocks. The apparatus is set up by placing one of the copper blocks on top of the acrylic base. The base has an integral sump, which will contain the meltwater from an ice cube. The acrylic tube is then placed over the copper block, in order to contain the metal blocks and ice cube. An ice cube is then dropped down the tube onto the block and the second copper block is placed on top. Immediately the ice begins to melt, due to the high thermal conductivity of copper (along with large thermal mass), and in matter of 10-15 seconds the ice will have melted and disappeared. By repeating the experiment using the steel blocks it can be seen that the ice melts more slowly, due to the lower thermal conductivity of steel. Each experiment can be timed, for more accurate comparison between the two different metals. The kit also includes two plastic insulating discs, which can be placed between the ice and the metal blocks to show that it is not simply the pressure of the top block which is causing the ice to melt. If repeating the experiment using the same blocks, it is better to allow the blocks to come back up to room temperature first (if repeatable results are required). Contents: • Acrylic base and tube • 2 x 0.5 kg copper blocks • 2 x 0.5 kg steel blocks • 2 x plastic insulating discs Also required: Ice cubes, preferably quite large.
