Ancient Roman Nanotechnology —- The Lycurgus Cup
In the 1950’s the British Museum acquired one of the most amazing archaeological finds from Ancient Rome.  The Lycurgus Cup is a beautiful 1,600 year old goblet crafted from glass by the Ancient Romans.  The cup depicts the punishment of Lycurgus, a mythical king who was ensnared in vines for committing evil acts against the Greek god Dionysus.  The craftsmanship and artwork of the cup are certainly amazing on their own. During the age of the Roman Empire the Romans were master glassmakers, producing some of the finest pieces of glassware in history.   However the Lycurgus cup has one incredible property that is goes far beyond traditional glassmaking.  When exposed to light, the cup turns from jade green into a bright, glowing red color.  For decades historians, archaeologists, and scientists had no idea why this occurred or how the Romans made the cup with such light changing properties.  Then in 1990 a small fragment of the cup was examined by scientists under a microscope.  What they discovered is truly amazing.
The Lycurgus cup is not only made of glass, but is impregnated with thousands of small particles of gold and silver.  Each of the gold and silver particles are less than 50 nano-meters in diameter, less than one-one thousandth the size of a grain of table salt.  When the cup is hit with light, electrons belonging to the metal flecks vibrate in ways that alter the color depending on the observer’s position.  What is even more amazing is that the addition of the particles to the glass was no accident or coincidence.  The Romans would have had to have known the exact mixture and density of particles needed to give the cup light changing properties.  This would have been done without the aid of a microscope, without the knowledge of atomic theory, and 1,300 years before Newton’s Theory of Colors.
Today the Lycurgus Cup has profound affects on modern nanotechnology.  After studying the cup, researchers and engineers are looking to adapt the technology for modern purposes.  A researcher from the University of Illinois named Gong Gang Liu is currently working on a device which uses the same technology to diagnose disease.  Another application of the technology is a possible device which can detect dangerous materials being smuggled onto airplanes by terrorists.  
The legacy of Ancient Rome continues.  Arena’s, baths, arches, and  nanotechnology.

Here’s a fantastic, easy idea we just came across – how to use eggshells to plant seeds. I love this one. There are numerous benefits to this idea:
1) You don’t have to uproot the seeds when it comes to time to plant them out – simply crack the shells and the roots will grow through! This saves you from potentially damaging the young seedlings – and the shells will break down.
2) The eggshells are biodegradable, so there is no waste.
3) The seeds benefit from the nutrients in the eggshells. Eggshell contains a good quantity of bioavailable minerals – especially calcium; a mineral that is not only essential for humans, but essential to all stages of plant growth.
4) You don’t have to use plastic pots, so it’s eco-friendly! Another win for the zero-waste home 
5) It’s free!
6) It’s fun!
This is a great tutorial with lots of pictures. Why not give it a go and let us know how you get on. Here is the link to the full tutorial: http://www.17apart.com/2012/01/how-to-plant-seeds-using-eggshells.htmlI’m about ready for an omelette!
