The spring that makes the lid close on my electric kettle isn't strong enough so when the water boils the lid lifts up about one mm. This reduces the amount of steam that passes near the thermostat vent, so the kettle stays on for longer than necessary. A telephone line insulator weighs about 2lb, so if I put one on the kettle lid it closes the gap and thus reduces boiling time. This saves 0.25p every time I make a cup of tea. After 400 cuppas I have save a pound. Bill
