I've just bought a lovely shiny hob-top/camping kettle on ebay. It's chrome-plated copper with coils round the base. I just raced it against my rapid electric kettle and it only took 30 seconds longer. So I am a happy bunny and I'm hoping it won't take 6 hours to boil on a camping stove.
BUT. It doesn't whistle . Can I buy a whistle to put on the spout? Does such a thing exist?
