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....

Watching seabirds in the Forth

Last weekend, Dad said I was going to have a surprise on Sunday morning. We got up early, and he told me to dress warm even though it was supposed to be warm anyway. We left the house at 7am, and I didn't know where I was going. He drove almost all the way to Edinburgh and parked right inbetween the Forth bridges. Then he told me that we were going on a seabird boat cruise that was part of the RSPB Scottish Birdfair !
