Tornado in a Bottle

On Tuesday we tried to make a tornado in a bottle with Ms Whelan.I did not know what logic she was going to use for our experiment. She said she might not get it right on the first time but she looked confident so I trusted her. She was ready and she put her hand on the top of the bottle and she turned it over and shook it around and poured it into a jug. You could see the tornado in the middle of the top of the bottle and it looked amazing.
So that was a success and we tried it again and that was also a success but the third time we had a little problem when she was pouring it in the bottle slipped out of the jug and it went all aver the place and it was a good thing we had the cloth so we got to do that again and we got it on target this time.
 It was a great success and now I am going to tell you how to do it. First you get a bottle of water, a jug, and a cloth just in case you spill it. Then you get the top and twist the bottle round, then you get the top of the bottle and put it in the palm of your hand, next you shake it around for a couple of seconds and finally you pour it into the jug and look at the top of the bottle near to the spout. If you're lucky you can see your mini tornado in a bottle.

From Liquid to Solid in Eight Minutes





























Last week I had to do an  experiment with cream. Cream is a liquid. It is lighter than milk and usually floats on top of the milk. I put 250 ml. of cream into a bowl. I got an electric beater and as  I whisked and whisked the cream got thicker and thicker.
 After 8 minutes the cream turned into a solid. I had made butter. I tasted it and thought  it was delicious. It didn't taste the same as normal butter because it wasn't salted.


Some children were amazed at the transformation.

After eight minutes the cream had changed into butter. 
This is what the butter looked like when we took it out of the bowl. If you look carefully you may notice a little buttermilk.


This picture of butter patties was taken in the National Museum at Collin's Barracks. They were used in the 20th Century to roll the butter.
