Ingebjørg and Tonia are very pleased with the result of their experiment which is under the coat on the table. They measured the Specific heat capacity of water using an electric kettle. Not happy with their result over 5000 Jkg^-1K^-1 they decided to insulate the kettle with a coat. Norwegians have good winter coats and Ingebjørg is Norwegian so the change was significant. You also get a nice warm jacket, even if it is a bit damp.
