How small is a coffee bean?

One of the early morning rituals that the Chinese Noodle and J like to engage in, ever since we've gotten home, is getting the morning coffee ready. During the week, it is just the measuring of grounds and water to make the brew. Once the weekend comes, however, J gets out the grinder and grinds up some fresh coffee to make a full pot. The Noodle loves to help hold down the button while the whole beans get pulverized into those fine, black crystals. A few Sundays ago, while J was busy attending to the pot, out of the corner of his eye he saw the Noodle take a whole bean from the bag. When he turned to look again, the bean had vanished. Upon being questioned, she stated in a matter-of-fact tone that she stuck the bean up her nose. Of course he panicked and asked again, and quiet calmly she informed him that yes, she had indeed put it up there. They both dashed upstairs, into the bathroom, where I was in the shower. He had her blow her nose, and sure enough, out came the coffee bean. Thank goodness she didn't push it in too far and that she's mastered the art of blowing air out through her nose!! So to answer the question 'How small is a coffee bean?', it is small enough to fit into a 3 year old's nostril. The consequence? She's been banned from grinding since the incident and has had to be content just to watch. So, do you think she has a future being a barrista at St*rbucks? Ha ha!!
