A young lady in Connecticut suffered from a form of cancer when she was 8, and learned that one of the problems was getting around when receiving chemotherapy, because she was connected to the pole containing the chemicals being put into her body. That pole is no picnic to move when you're 8 and taking chemo.
So now, at 11, she invented a backpack-style bag a person can wear which will do the same thing as the pole contraption does. She won an inventing contest and has a patent; now all she needs are investors to start production. I imagine that will happen; good job, young lady.
