Yeah, sounds absolutely wonderful. Per square foot, how much does it cost and how durable/fragile is it?! Technology is getting better and better. And this is just 2018. The Model T about 100 years ago. What will there be 100 years from now?! Oh yeah, the flying car was in Popular Mechanics in about 1966. Every college physics dept. should have a tech fair just like the typical high school science fair. The college kids would have to design a toy or a widget which could do something. And then each college physics dept would compete in the national arena. With the entire school chipping in, the physics toy competition could be amazing.
