Get Emotional with Science.
On Friday 15th of November a man called Paul came to our school and gave us a demonstration on a number of Science experiments. Fourth, Fifth and Sixth class along with 5th and 6th class from Ringiskiddy N.S. gathered in the halla to watch the show. He showed us how magicians use science in their tricks. First of all he got a volunteer from the crowd which was Christopher Sisk from 6th class. He got a table cloth and put it on the table, next he put a plate and a knife and fork and then he got Christopher to pull the cloth from under the plate and the knife and fork. Everyone thought it was not going to work, but it did! It was a brilliant trick!
One of his best tricks was when he blew up marshmallows to double their size. He did this by placing the sweets into a container. He then sucked out all the air from the container. The marshmallows doubled in size. There was a little switch on the top of the container that he pressed. This let all the air back into the container which made the marshmallows shrink back to their normal size.
He also did a trick where he got three cups and put water in the middle one but what nobody knew was that he put polymer in the cup with water so it soaked up the water so when he mixed the cups up and the children picked the cup they thought the water was in but there was none. He explained how it happened and then got his next trick ready.
One of his tricks was where he had taped a stone to the side of a roses tin. He put it on a ramp and when he let it go, it rolled up instead of down. He explained how the gravity pulled the heavy stone towards the floor so the tin rolled up the ramp.
He told us a story about a guy named Mark from the U.S.A that came up with a new type of paper aeroplane that was circular. It was Paul’s favourite science toy. He showed us how it was made from paper and then he threw it but it did not go very far, but then he got a slingshot and twisted it, it went way farther than when he threw it by hand. He also showed us how to show how big your lungs are. He got Tianna as a volunteer to blow into a bag. She blew four times and filled quarter of the long bag.
There were many more experiments that we could write about but it would take us all day! We really enjoyed all the experiments and we hope that Paul will come and visit us again very soon!
