Graphene is a single-atom thick layer of carbon atoms closely linked in a hexagonal 2D sheet. Once formed, this stuff is so strong, you couldn’t pierce through it with anything less than about 5 tons crushing down on a point the size of a pencil tip.
In Non-Newtonian fluids, the viscosity or “thickness” of the liquid changes when it is stressed. This means that when they’re shaken or stirred, the liquid becomes either “thinner” and flows more freely, or “thicker” and resists movement.
You can only do one thing at a time. First ask yourself “What one thing could I do that when accomplished, will make everything else easier or unnecessary?” Once that one thing is accomplished, ask yourself the question again and repeat the process.
