Air Resistance - The Mirror Master uses a special mirror to shrink The Flash so he's knee-high to a mouse. As he avoids the villain the Flash tumbles from the top of a building, but as the editor notes "It is a fact that tiny animals can fall from great heights without injury! This is because of the slight weight and the buoyancy of the air!"
Radiation - The last panel is packed with internal dialogue as Flash explains how he'll use "certain radiation" to grow back to his full size. A quick search on the internet shows that, yes, some amphibians, fungus, and plants grow larger under UV or infrared radiation, but the same search will also yield results showing that some tumors can grow and metastasize under similar radiation. Hopefully The Flash knows what he's doing, since he's full size a page later where we see my favorite "Flash Fact."
Tornado Forces - As the Flash erupts a wall the editor notes "just as a tornado-driven straw can penetrate several feet of solid oak, so can Flash at super-speed penetrate solid walls!" This was one of my most favorite Flash facts, as well as a convenient mechanism for speeding up the action. I mean, this "fact" gave the Flash the ability to run through walls -- way cooler than Superman bursting through the wall. Fortunately for us we're dealing with fiction, since this ability is about as realistic as time-travel.
It's true that a tornado has a lot of force, and can send field grass flying at speeds greater than 200 mph. But most evidence and experimentation doesn't show that the straws pass through trees without harm to either object. MythBusters had an episode dedicated to answering the question whether the grass could go through the tree. In their experiment the grassy missile penetrated less than an inch into the tree.
"Propelling a piece of straw at a palm tree at a distance of 50cm at 320mph (the world record for recorded wind speed at ground level), the straw only managed to penetrate the tree a quarter of an inch. Even firing at the tree while it was bent (to increase the size of the pores in the surface of the tree) at point blank range added no additional distance into the tree. A piece of reed was tested as the sturdiest organic object that might be mistaken for a piece of straw. At both ranges, the reed only managed to go about two inches into the tree. Additionally, Jamie tried a piece of piano wire, and at 50 cm, it flew not only through the tree but through a sheet of plywood on the wall behind it, partially embedding itself into the cement wall."
Regardless of whether the straw could pass through the tree, if the Flash tried to use his super speed to zip through a wall, he'd probably end up partially embedded in it, or considering that he doesn't quite have the same structure as a reed, maybe splattered against it.
