Parallelepiped frame with base, which can be folded obliquely (four vertical rods, two bases, and a median articulated support)
The dimensions of the parallelepiped are not smaller than 140x200 mm
Device to show balance of bodies with support base

Peripheral groove wheel on support
Rotation axis
Hooks on two sides
Material: Polypropylene Pulley
Mounted in an Aluminium frame.
Diameter 40 mm
Thickness 5 mm

Long cylindrical helical spring (resort)
Shape : Cylindrical
Color : Silver
Material : Stainless Steel
Diameter 20 mm
Length : 3 meters

Support on which 5 steel balls are attached with two wires on a straight line
At the deviation of a ball from the extreme, the impulse and energy is transmitted to the ball in the opposite extreme, without changing position of the intermediate balls
Minimum balls diameter 15 mm
The length of the suspension wire 120 mm

Transparent glass tube
Diameter 30-100 mm
Minimum length 1,500 mm
One end closed and the other end with a sealed lid with tap and air outlet connection
A wedge, a piece of sponge and a metal ball, 5 mm external diameter

Complete demonstration of Pascal’s Law.
The apparatus shows that a change in pressure in fluids is transmitted equally in all directions to all parts of a fluid.
The device contains a hollow sphere connected to a hand pump with plunger that applies pressure to fluid in the ball.
The fluid exits all 10 equidistant nozzles in the ball with equal force in all directions. With instructions.

Power source for teacher, alternative power source (two terminals) and continuous power source (other two terminals), adjustable from 2 to 24 V (minimum), graduated, maximum current 5 A with short-circuit protection.
Voltmeter and ammeter for voltage and current indication
Main’s connection plug with conductor for earth connection.
Power supply 220 volt

Mechanical or electrical installation with minimum power of 90W for evacuation and pumping of air in the experiments for studying gas processes
Provided with a tap that allows the air to be exhausted up to a pressure of 130 Pa
Pressure up to 0.3 MPa can be obtained by pumping
