My brilliant new clever invention for cleaning bones

For ages I have been thinking of a better way of cleaning bones with biological washing powder. I have been using biological washing powder to clean for almost two years now after it was recommended when I visited Perth Museum. I wrote more about it in my complete guide to cleaning bones, but the way it works is it contains enzymes which eat away and dissolve fat. 

Up until now the way now I have been putting the bones to be cleaned in a plastic container, adding the biological powder, then adding hot (not boiling) water then leaving it for a while, then adding a new lot of hot water and powder. The problem is that when the water cools it doesn't clean as well so it takes lots of changes of water.

So I have been thinking for ages for a way to do it easier, where it's nice and clean, and it heats itself. Then two weeks ago I was at a nearly-new sale with my family and Dad saw this and wondered if it might work....

Half term trips: the Scottish Seabird Centre

This is the third half term trip I have written about after Auchingarrich Wildlife Centre and the National Museum of Scotland, and it is one of the most special trips of all because I was meeting Mrs Powell who is also a bone collector. We had swapped some amazing skulls before and I had asked her if I she would like two red deer skulls (one of which was this one). She said yes and offered to swap for a pig and a seal, which are amazing and  I am going to write about later. She said maybe we could meet up in person, and she lives in the north of England and I live in Scotland and when we looked on a map the Scottish Seabird Centre was  in North Berwick which is about half way between.
