How about something to help open jars? I always end up running it under hot water and using a towel to open it up so what about a pad that heats up when you put it on a lid? It could have grippers like a bunch of tiny suction cups that grip the lid while you twist.
The only other idea I have is something like a rubber blanket that you plug into the cigarette lighter of your car and put over your windshield. It heats up and melts the ice off instead of having to scrape it. Or you could put it on right after you get out of the car and it will keep snow and ice from sticking to the windshield.
That's all I've got. Good luck to yoU!

A simple description of quantum gravity with the equations written on cardboard should win him the 8th grade prize.
It will win a Nobel Prize in physics too.

How about a cardboard message holder that you can slide under the door if you have to pass a message along to someone who is in the bathroom and can't come out yet?

How about you invent clear metals,that's right metals you can see through. Just think, windows as strong as the steel plate they would be made from. Just remember when you make it I get some of the profit.
