Good Morning! My name is Rick Hall. I am from a company called IGNITE in the United Kingdom. Today I am going to show you an experiment which I call the Confuser Phone. This is the kind of simple experiment which gets a lot of people interested in science and sparks their curiosity. So, let’s start how to make a Confuser Phone. The materials are very cheap and you can buy them easily from a store. These are EAR DEFENDERS – they are used to protect the worker’s ears in a noisy work place. This is a hose pipe from a washing machine. To finish it off you need some plastic bottles. These happen to be fruit juice bottles. Cut off the bottom of the bottles. Glue the lids of the bottles to the hose pipes. Now you can screw the bottomless bottles on to their lids. Make a hole in the EAR DEFENDER so that the hose pipes can be inserted. Now this is the complete Confuser Phone. Why is it called the Confuser Phone? It should be very simple and obvious. The sound comes through the bottle on the Right and ends up in your Left ear. And the sound from the Left comes though the other bottle travels the hose and ends up in your Right ear. These children will soon demonstrate what the Confuser Phone does. You know what our senses are - Eyes, Nose, Ear, Mouth and Touch. We’ll do an experiment about sound and our vision. We will also do one about touch. Please close your eyes and point to us from which direction the sound is coming. “Hello!” the sound is coming from the Right. “Hello!” the sound is coming from the Left. Crackle your fingers on the Left and the boy says the sound comes from the Right. Crackle your fingers on the Right and the boy says the sound comes from the Left. Clap on the Left and boy hears it in the Left ear. Finally confuse the boy with everyone clapping loud.
