The one thing that most parents will tell their kids is to never stand too close to the microwave due to radiation and thanks to the Proinjector, that will never be a problem.
Take a microwave and a projector, mash them together and you get the Proinjector by Hwang Jungjoon and Lee Jaeryong. As strange as this hybrid may sound, it does serve a purpose. The idea is to have the microwave project the image of the food that's currently cooking inside. This way, people will no longer have to press their nose against the microwave and be exposed to radiation. The focus can be adjusted with a dial so that the user can get a clear image for their own vision.
At the moment, the Proinjector is a concept design, but hopefully it'll make its way through homes soon.
