Periodic Table of Videos viewers may have noticed our new video this week about element 65 - Terbium.
It contains footage shot in Yttertby, Sweden, where the element was discovered.
I travelled to Ytterby with Pete Licence in November 2008 (was it really that long ago!?)
Some photos from the trip are here.
We made a series of films, the main one being this.
However while we were in the snow-filled quarry, we filmed little updates for the four main elements named after the village (Ytterbium, Yttrium, Terbium and Erbium).
With the publication of this week's Terbium video, I've now used all four of those extra snippets.
