Pascal Ball Pascal Ball
S111-1

This device is used to show that water pressure will transmit in all directions. Consists of a hollow sphere connected to a hand pump. The sphere has an outer diameter of 3"and a capacity of 250ml. Ten projected nozzles are evenly distributed on the sphere. 14x4x4"
pascal's law apparatus Pascal's Law Apparatus
S111-2
This kit demonstrates Pascal Law " An external applied to a fluid confined within a closed container is transmitted undiminished throughout the entrie fluid".
Liquid (Hydraulic) Internal Pressure Demo Kit
S111-3

This kit includes a mini fluid nanometer and a fluid press tank equipped with synchronizing wheels, belts and hoses to obeserve fluid internal pressure changes along with the depth, i.e. There is an increase in pressure as the length of the column of liquid increases, due to the increased mass of the fluid above it.
hydraulic pressure Gravity and Hydrostatic Pressure
Pressure in a Container
S111-4
The contaner with several spouts at different levels where different pressure can be measured when fill with water. It perfectly reconfirms "Gravity is the principlal cause of hydrostaic pressure". Nanometer is not included.
hydraulic pressure demo kit MS111.6 Hydraulic Pressure Demo Kit
S111-6

This kit allows student to observe hydraulic pressure being built.
boyles law demo Boyle's Law Demonstrator
S137
This kit demonstrates Boyle's Law " The absolute pressure and volume of a given mass of confined gas are inversely proportional, if the temperature remains unchanged within a closed system".
Hydraulic Turbine Experiment Kit Hydraulic Turbine Experiment Kit
Water Wheel
S307-7
Wheel turning is driven by free falling water which converting the energy of free-flowing or falling water into turning forms of power.

Convection of Liquid Glass Frame
Illustrate the properties of convection currents!
The water and dye-filled glass frame is heated at the bottom corner. When observed, the movement shows the path of the convectional current.

Convection Apparatus for Liquid Convection Apparatus for Liquid
305

An all glass constructed Cartesian Diver with a red band to make the diver more visible.
Cartesian Diver Unit Cartesian Diver Unit
305-1

Supplied with a Diver and Hydrometer Jar.  A diver is placed in a cylinder of water.  Pressure on the cap forces water into the diver causing it to sink.  
Specific Gravity Bottle Specific Gravity Bottle
412

These uncalibrated specific gravity bottles are excellent for determining the specific gravity of liquids. The borosilicate bottles feature a ground stopper for a precision fit.
412-1 10ml
412-2 25ml
Harbottle Apparatus Harbottle Apparatus
791
The Harbottle helps students understand the meaning of fluid pressure and pressure reduction. 
A Harbottle is a round, glass, container with a balloon stretched over its opening and a hole in
the flattened base that is fitted with a rubber stopper. Students are amazed when the balloon remains inflated inside the bottle even though it
is not tied off or sealed.
