Pascal Demonstration
To teach Pascal’s Law and application of hydraulic press. By alternately applying force on a large and small piston, students will experience the mechanical advantage of one over the other. This device can be used to discuss the many uses of hydraulics such as power steering, hydraulic jacks, shock absorbers and auto braking systems.

Pascal’s Law Apparatus
This apparatus is used to demonstrate Pascal’s law. It demonstrates that pressure of liquids varies with depth and is independent of the shape of the vessel. It is mounted on a moulded plastic base, into top of which one of the four vases of differing shape may be screwed. All the four glass vessels have identical bottom opening. A movable index is provided on the vertical rod to enable the height of water in vases at same level.

Pascal Ball
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.

Speed of a Bubble Set
The set consists of three rugged, sealed, transparent plastic tubes containing colored fluids of three different viscosities. The bubble in each tube rises at a constant speed which depends on the type of fluid, the angle at which the tube is inclined and to some extent the temperature. Students track the time taken by an air bubble to move from the bottom to the top of 3 different colored tubes. From this they can link the mathematical concept of slope to the physical science concept of velocity. Includes instructions.

Pressure Under Water
Students can quantitatively see how pressure on an object changes as it moves deeper under a fluid with this interactive density pressure manometer activity. A hollow drum covered with a rubber membrane is connected to an open end manometer. When the drum is pushed under water, the pressure on the rubber membrane increases the pressure inside the tubing, causing the manometer fluid level to change. The kit includes a tall vertical container, rubber drum, tubing open end manometer and demonstration guide.

Venturi Meter
To demonstrate Venturi effect. Made of glass with three side tubes for attaching an included three-leg manometer. The manometer is filled with colored water to show the relative pressures at significant points of the tube when gas is flowing through it. With Instructions. Without Clamp.

Mechanics
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.
