This is used for demonstrating the chemical composition of water by volume and the electrochemical equivalent of hydrogen by electrolysis of water. Platinum electrodes mounted in rubber stoppers are used for the electrolysis of acidified water but carbon electrodes must be used for ammonia soluti...

An amazing paint formula which changes from opaque to transparent when it gets wet. Typically the paint is applied over an image to produce a plain white surface as the paint dries. If the surface is then brushed over with water the hidden image is revealed. As the surface dries it returns to its...

The amazing ferrofluid is a truly magnetic liquid that consists of micron size magnetic particles (magnetite) in a mineral oil. Particles are coated in a surfactant which prevents them clumping together.

When a magnet is in close proximity the magnetic particles in the Ferrofluid take up th...

A pair of short S-type electrodes for hanging on side of a 100cm beaker. These carbon elements are attached to stiff wire connectors with shrink-fit plastic insulation.

An electrical connection can be made by connecting crocodile clips.

The front of each card shows a beautiful photograph of the element, while the back includes detailed scientific information and a description of the sample shown on the front. Laid out together the cards form a periodic table over 7.5 feet (2.3m) wide.

For incorporating thermometers into Quickfit jointed-ware assemblies. Pocket fits most Quickfit still heads.
