1000/619: 23 Oct 2011: Rocks

Buy these in a shop and you'll be paying a couple of pounds each - on the other hand - you can collect them for nothing from the beach and give them a good boil to sterilise them. Guess which I did!

I'm no geologist so I'm not quite sure what these are beyond being relatives of granite - but the range of pinks yellows and oranges they display on the aquarium is worth seeing.
