My next project will solve a fundamental design flaw which exists in many otherwise comfortable houses, hotels and B&Bs: something that causes fear and trembling first thing in the morning, however peaceful a night you may have had.
This world-changing invention will be a compact telescopic rod, with a handle at one end and a rubber-coated three-pronged tripod-like fork at the other. It will be lightweight and inexpensive. It could even be a Kickstarter project. It will have just one simple function.
It will allow you to turn on a shower, and get it up to temperature, without having to stand underneath it.
