What is one thing that should be invented?

...Me too diana, one that wouldn't cost an lot of money also......

There use to be an tv show called "Tool Time" with Tim Allen and he showed inventions on it one day, one I like the best was the closing the doors, and windows and pushing an button and your entire kitchen was washed down with an sprayer, water went into the floor, and blowed itself dry. Unfortunaely as he told about it ...his assistant was left in the room and all you saw between the windows of the clsoed doors was him begging to get out with lots of soap bubbles in his hair. You have days when you wish you could do things like that, just push the doors shut an press an button.
