Premium Potato Clock
This fascinating potato clock kit includes everything you need to
make a potato-powered clock - apart from the potatoes themselves!
The apparatus demonstrates how a clock can run without
a conventional battery - using fruit, potatoes or other starchy
vegetables.

Brownlee Water Electrolysis Apparatus
Brownlee’s Water Electrolysis Apparatus is used to demonstrate that electrically conductive liquids can
be decomposed and resolved into their constituent elements by means of a unidirectional electric current.
The gaseous components formed by this method can be trapped and their relative volumes estimated.
The apparatus consists of a support which rests on a 1 litre beaker or jar and has two clips that each hold an
inverted test tube. Platinum electrodes are positioned under the inverted test tubes and are attached to insulated
connecting rods which are attached to binding posts mounted on the support. When the beaker is filled with
a water-based solution and a direct current is passed between the electrodes, gases will begin to collect
in the inverted test tubes.
Requires a 1 litre beaker or jar, 6V battery or 10V DC power supply (not included)

Kinetic Gas Theory
Demonstration
Apparatus
This apparatus allows students to study the
motion and behaviour of molecules in gases.
An electric motor running at 4 to 12V DC
vibrates a small platform inside a transparent
tube, so that a number of small steel balls
is vibrated violently inside the tube.
An increase in the violence of the vibration
simulates an increase in gas temperature
and an increase in the weight of the ‘float’
simulates an increase in gas pressure.

Demonstrates kinetic gas theory

Supplied with balls and 2 floats
