Firstly, before I become all “left-brained” about this, imagine actually doing it. Close your eyes if you need to. Imagine the feel of an AA battery in your hand – the size, the weight. Notice how solid it is. Now imagine resting it between your lips – the feel of cold metal. Picture yourself pushing the AA battery, with the tip of your finger, all the way into your mouth and towards the back of your tongue. Now imagine swallowing. Go on – really imagine it.
