Ferrofluid can be used in both Science and Design & Technology due to its properties as a magnetic liquid.

A blue pigment that changes colour according to lighting conditions. In sunlight or ultra-violet light, the pigment changes colour immediately and dramatically.

Polyox (polyethylene oxide) is a non-toxic, long-chain polymer with a high molar mass. A solution of Polyox (approximately 1% w/v) behaves as an 'elastic liquid' and will even 'self-siphon'.

These 5.5mm diameter springs are made from shape memory alloy. At room temperature this spring is soft enough to pull out to approximately 50mm by applying a small amount of force.

A convenient starter pack of Smart colour pigments which can be mixed with an acrylic base medium.

A pack containing samples of several smart materials, in a re-usable plastic storage case.

Smart putty, or otherwise known as visco-elastic polymer or dilatent compound, is ideal for project work in design & Technology. This material has the remarkable property that it usually behaves as...

Smart wire is a shape memory alloy (SMA) that changes its length with a useful pulling force when a small current is passed through it.
