Molecubes are tiny cubes that are made out of atoms and molecules. They are so small that if you put one million of them together, they would fit in the palm of your hand. Each Molecube has hundreds of little atoms inside it and they are held together by the force of their attraction. Molecubes can be used in a variety of ways like in materials science, to create new materials, to capture and store energy, and even to make 3D pictures and videos. Molecubes offer exciting possibilities for the future!
