For the sixth day of Christmas we've gone with carbon, element number six and a

particular sort of coal, called anthracite, which is almost pure carbon. This is a sample

of anthracite that was sent to me by a YouTube fan called David Harris; I think in

Pennsylvania. Anthracite is really, looks rather beautiful, it looks almost like

bits of metal. It's very light and it's almost pure carbon. I think after

Christmas we're going to get Neil to burn some of this, but David also sent me some ash

that is left over from the burning. Some of it went into the bottle, I put it into

a bottle, but one piece was just too big and what's interesting about this ash.

which I think was burnt in a furnace, is that it's very light. I think these

are just bits of minerals which were included in the lumps of anthracite

and they didn't remove properly. According to David that anthracite

with almost a colorless flame. So again, that's something which we can test in

a future video. And although it's coal, it's not at all dirty. I can rub it on my

hand and you can see none of it comes off. So, for the sixth day of Christmas

element carbon in anthracite, a glowing guitar plectrum,

four drinks containers, three chemical badges, two periodic table bed covers,

one piece of tartaric acid from a Swiss wine barrel. And let's see what's number seven.
