If I could I would design a headgear type of gadget that would let the user use telekinesis. I would have one strap that raps around the users head with a few things on the side that make it function, like batteries. It would function as two arms and only have the reach distance of the average humans arms, depending on the users age. It would mostly benefit people who are paralyzed like Stephen Hawking. It would also benefit really lazy people, old people and people who have to carry a lot of things for a job maybe. It could help a person clean or it can help heavy lifter people. I would hope that it is used for positive things, I would feel horrible if people took advantage of it to do bad things with.
