Liquid Crystals—
How Do They Do That?—
Chemical Demonstration Kit
By: The Flinn Staff
Combine two clear liquids and heat them, then watch as the mixture produces vivid
color changes from red to green to blue as it cools. Liquid crystals have properties
in between those of solid and liquids—molecules move independently as in a liquid,
but they also tend to orient or align themselves like a crystalline solid. The alignment
of the molecules changes with temperature and produces fascinating color changes.
A simple introduction to the world of nanotechnology! Teacher Demonstration Notes,
reproducible student worksheets and answer sheet are included.

Aerogel
A little piece of the future—right in your classroom! Aerogels are a diverse class
of the world’s lightest solid material, composed of up to 99% air by volume. This
low-density, porous material is already used for insulation, high-energy radiation
detectors, and oil remediation—it even went into space with the NASA probe Stardust
to capture particles from a comet! Silica aerogel is an excellent insulator against heat
and conductivity—if one side is heated, the other side will remain cool. High-quality
silica aerogel is highly transparent with a light blue color due to Rayleigh scattering
through the aerogel’s nanoparticle framework. An unforgettable material to connect
classroom concepts such as density, transfer of heat, conductivity, and properties
of gases, solids and liquids to real-world applications in engineering and modern
materials! Note: Sample is fragile and should be handled with care.

Nitinol “Live” Wire
Wire with a memory! Nitinol wire was discovered in 1961 and has “shape” memory.
When placed in cold water it can be bent into any shape. Put into hot water, it springs
back to its original shape. Shape memory alloys are discussed in the provided
instructions. Price is per inch; may be purchased in any length requested.
