Observing The Reaction Of Dry Ice In Water
I always wanted to try this (put dry ice in water) and last year I got the opportunity. When I bought some meat from Donald Russell it was delivered packed in dry ice (frozen CO2) i.e. solid carbon dioxide. This dry ice was used to keep the meat cool in transit. The meat and dry ice are transported in a polystyrene box which provides lots of insulation. However the heat does percolate a package like this and the dry ice sublimates, but usually there is some left on arrival. If not the meat temperature may rise too high. So I had a source of dry ice.
The first thing I wanted to do as soon as the meat was stored in a cool place was put the dry ice in water and watch it bubble away and the vapour flow out and down the side of the container. I caught it on video below:
Should you practice teapot cleaning or not?
Some people think teapot cleaning is unnecessary and that it spoils the flavour of the tea. If they have traditional brown earthenware teapots they probably don’t see all the tannin stains on the inside. With a stainless steel teapot you see them all and they start to form very quickly from new, or after cleaning. Tannin makes a teapot look disgusting. Not something you want guests to see when you make them a cuppa, or when they make one for you.
Teapot cleaning can be avoided by keeping it clean. One way is to make sure it’s emptied and rinsed out immediately after use. Letting it stand with old tea in it until the next mash allows the tannin deposits to grow. Continue reading “Teapot Cleaning Methods”
Fieldfare – Turdus pilaris – a member of the thrush family.
When Fieldfares visited Alvaston Derby I was ready with my camera.
On 22nd January 2013 Fieldfares visited Alvaston Derby. I saw them in my garden and the garden of a friend in the same street. Fieldfares migrate to England in winter from northern Europe but this was my first sighting of them. It was a bad winter in early 2013 So I’m sure they came looking for food.
Here are some pictures of one sitting in the snow on my lawn. It was very good of it to stay settled for quite some time while I took these pictures and two videos:
- The first continues to show the same bird as in the still photos sitting in the snow.
- The second shows a pair hopping about in a tree and feeding on berries in my friend’s garden.
