Nanomaterials workshop<br />
How do materials really work? How does nanoscale<br />
structure change the properties of a material? From<br />
polymer slime to non-Newtonian fluids, students learn<br />
about what makes up materials on the nanoscale, and how<br />
we use this to make something useful. Sand that always<br />
stays dry, beads that change colour in the sun, and how<br />
Polaroid sunglasses work. Plus, a discussion of some of<br />
the latest technologies – including flexible screens and<br />
organic LCDs!<br />
A mixture of cornflour and water is an<br />
“oobleck” – it appears runny if you work<br />
slowly with it, but…<br />
Students from Yirara College investigate UV<br />
sensitive beads<br />
Running on the oobleck<br />
compresses the cornflour<br />
particles, making it instantly<br />
solid!<br />
Microscopic bumps on the surface of a Mentos lolly cause a massive release of carbon<br />
dioxide from Cola – producing a dramatic fountain for a finale!<br />
