Uneccessary things that Haven't been invented yet

Just the title makes me smile. Think of thigs that DON'T (we hope) currently exist, that are possibly feasible to create.

II. The automatic toilet paper:
It's positioned somehow under the seat, and does it's duty after you've done
yours
"Look Ma! No hands!!"

Come, my friends, let's create an entire catalogue. Clearly, there is a need for the uneccessary!!
