Battery Powered Acceleration Timer
This battery powered timer produces 30 to 50 marks per second for dynamic experiments. 1.5V motor operates on two D-cell batteries (not included). Wooden base improves stability, reduces vibration, and permits attachment to a ring stand post. Striker mechanism acts against an aluminum plate to produce improved-dot definition on the ticker tape.

Bell Jar And Vacuum Pump Set
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.

Bernoulli Tube
To Investigate the relationship between the speed of a fluid and its pressure. Consists of a glass Venturi tube with two different diameters. One pair holds a U-shaped tube in which a color liquid can be placed to demonstrate the different pressures exerted when air is blown through the tube. It includes two rubber tubes and glass Venturi tube fitted on stand.
