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.
Description :-
Tuning Fork Activator is used as a surface to gently strike the tuning fork to activate vibrations.
Rubber activator is tapered so the bottom is wider for stability.
Made of solid rubber.
