STEP TWO: Insert the needle of the marinade injector into the orange, stopping as close to the center as possible, and then inject. If you want to, you can pretend you're a doctor while doing this (you want to). Repeat as wanted/needed.
STEP THREE: Store in the fridge for 24 hours (not required, but recommended).
STEP FOUR: Juggle oranges while you walk through security (NOT REALLY). Peel and enjoy.
