Smart sand is a new revolution that hasn’t been completely finished. It is still under revision but the purpose of the sand is to duplicate any and all shapes and forms that it is placed next to. It can mimic the shape and image of any object that you place next to it. The sand is currently a project at MIT, hopefully in time they will be able to use it in real life instead of the simulated 3D that they put it in. Imagine if something like this could duplicate food, science has come a long way and a positive one at that.
