The ideal demonstration kit for smart materials this smart materials demo box (manufacturer’s code 233-020) has everything you could possibly want. With 33 different types of materials and a handy case to store them in this is perfect for demonstrating to groups or allowing you to get a close look at some of the more unusual materials around.
What’s in the kit?
This kit comes with 33 materials which fall into six different categories:
Thermally responsive materials – these include pigment and thermofilm which change colour when heated to around 27°C (warm hands or breath). Also includes phase change material which has an activation temperature of 23°C and can be used as a temperature buffer.
Smart alloys and polymers – these include materials such as memory wire and two-way memory spring which changes shape if heated in hot water and shape memory polymer which changes shape above 70°C. Superelastic wire which extends when pulled and snaps back into shape when released and smart putty for demonstrating Newtonian fluids are also included as well as a rare earth magnet for demonstrating the most powerful magnet in the world.
Glow in the dark film and UV fluid and beads - experiment with these to see which light sources have the best effect, create void pictures and warning signs and see the amazing light display created by the optical fibre and LEDs.
Fibres and woven materials - these contain many samples of very different natural and man made fabrics for you to compare the properties of each. Cocoons, Kevlar, carbon fibre fabric, ripstop nylon, silk, lycra, ecofilm and carbon fibre sheet are included in this kit. Ecofilm is an intriguing plastic which disappears almost instantly when it gets wet.
Special polymers - fascinating man made substances including Polymorph, Hydrogel and Expancel. Polymorph comes as hard pellets and becomes a malleable soft plastic in hot water. Hydrogel can absorb up to 500 times its own weight in water. Expancel expands up to four times its size when heated above 95°C. Just add water to the chromatic alginate and it becomes a fluid that can be easily moulded around an object.
Nano materials – explore the interesting features of QTC pills, money and chameleon nano flakes. See what happens to QTC pill’s electrical conductivity as it is compressed, watch the chameleon nano flakes change colour according to the angle they’re viewed at and see the recycling powers of money when it reaches the end of its life with the 3 x 3 mm pieces included.
Some experiments require hot water or a power source please check the activity booklet before starting any experiments.
