STRANGE Sand Acts Like Liquid

Hello, Dianna. I hope you read this post. DC COMICS' THE FLASH: Let's assume Barry Allen had actually acquired the capacity to move hyper fast without necessarily developing proportionally hypertrophic legs etc. In a fictional world still totally ruled by our laws of physics (forget Superman's flying etc.), how would it actually be for the Flash to tide up his house hyper expeditiously? I think it would be totally different from how the comics and TV series depict it. Lots of hyper agile stops and goes, lots of attrition, huge inertia involved all the way. This would provide for a very interesting computer simulation.
