I'm the prettiest princess in all of the land!

The Christmas tree that science built - hour ten


It has certainly bushed up to an impressive degree. Thanks science! Tomorrow we will subject some of the fallen (and seemingly insoluble in the solution which birthed them) crystals to raman spectroscopy.

We have yet to place the star atop it.

The Christmas tree that science built - hour three


One of the perfectly respectable and upstanding gentlemen of science working in my office decided that our shared room was simply not festive enough. The answer to such a problem was simple: a magic crystal tree. For those not in the know such wonders consist of a cardboard tree, decorations and a sachet of magic liquid. You pour the liquid into a dish and then plonk in the decorated tree, within am hour you start to see fluffy green crystals growing upon the tree branches. And so started epic science arguments about the witchcraft contained within the solution. A little research found out that you can grow these fluffy crystals using a mixture of sodium chloride, ammonia and "laundry bluing".

Knowledge of the ingredients led to further arguments. Sodium chloride crystals don't look like that, they are growing too fast for something containing hydrophilic sodium ions, what is the ammonia for then? And what is this damn "laundry bluing"? Just a dye? Something else?

And that took us to this: http://www.chymist.com/Crystal%20tree.pdf

So they all seem to be somewhat essential. Our final "agreement" was that the solution is a mixture of ammonia and sodium chloride while the cardboard has been soaked in the "laundry bluing" (which it turns out is a colloidal suspension of the Prussian Blue pigment). The green parts have also been soaked in a dye giving is the lovely green crystals.

Of course, there will be further trials. We need to grow some comparison sodium chloride crystals, some with ammonia added and other bits and pieces.

First of the season


Every day should start with the fabled Lindt golden reindeer*.

Happy first of Advent Calendar


You are now legally obligated to commence feeling festive.

Oh, and I know this is an awful photo - for some reason the advent calendar was really fighting not being covered in glare and my phone's ability to crop photos is slightly limited meaning that this one is weirdly off centre with a bit much "plain white wall".

Nabaztag en France


It turns out that there is a new model of everybody's favourite wireless smart rabbit. Just away from the opera a vast department store had devoted its windows to such technological wonders dressed by various designers
