Rubber Hammer, Medium

Description :- This setup consist of a metal plate and a hand vacuum pump mounted on a heavy metal base. A rubber seal is provided on top to perform a variety of bell jar experiments.

Description :- Hollow wooden sounding box 1290 x 130 x 110 mm, with mm scale, has two fixed bridges 72 cm apart over which wires are stretched. To one wire is fitted a spring balance reading to 100 N x 5 N and its tension can be adjusted by a winged nut and measured. Another wire passes over a pulley and can be loaded as desired. A third wire, for comparison, can have its tension adjusted by a wrest-pin. With 3 movable bridges, wrest-pin key, spring balance, and set of four wires of different diameters, each 1.5 meter long, without masses.

Description :- Set of eight copper pipes with tuning fork (256 Hz) to show how resonance tones can only be created from certain pipes. O-rings are attached to the ends of the pipes which protects the tubes from the drop In.

Description :-
Simple, innovative kit allows you to perform a number of experiments on vacuum and air pressure. The kit clearly demonstrates the method by which a pump works. Also illustrates that air has mass and helps find its mass and density. Explain the effect of surrounding air pressure on a sealed balloon. The balloon will expand when the surrounding air is removed. And also demonstrate that liquid boils at reduced temperature when the surrounding air pressure is reduced with instructions.
