Not silly at all Janet! I tested precisely this with water and ink
before I started mixing. I drew water up first, and then drew in a tiny
bit of ink. The ink was immediately mixed through the whole syringe, and
what initially came down the tube was perfectly mixed. The old NPH
insulin needed thorough mixing because the white insulin crystals are
much heavier than the solution they're in. With R & H the solutions are
identical, I believe(?), and there's a lot of turbulence as it shoots
into the syringe chamber from the tiny needle opening.
