Ever wonder what in a particular material? Here's an inexpensive way to find out: A DIY Mass Spectrometry kit!
… or rather: a smart application of the DVD diffraction grating property. Now you know what I'll be doing this weekend with the kids – not quite a spectrometer yet, but we'll be playing with various light sources and spectra.

Public Lab DIY Spectrometry Kit
This DIY kit helps analyze materials and contaminants. We need your help to build a library of open-source spectral data.

You might want to be careful in the wording: this Public Lab DIY Spectrometry Kit has nothing to do with "mass spectrometry". The former is optical spectrometry which separates wavelengths into their sizes (i.e. provides a spectrum), and the latter separates out particle (e.g. atoms, molecules) masses according to their weight.
very cool idea.
Really?, that is awesome!
