But in all cases, they're caused by comet debris, and they should flare up each time the Earth crosses the comet's path. But as it turns out, every meteor shower had a point in its past where it happened for the very first time. In all of human history, we've never recorded one that occurred for the very first time where none happened before. Well, for those of you who want to take the chance to be a part of it, this coming Friday night/Saturday morning, look for the Camelopardalids, making their Earthly debut this year!"
Today's scientific question is: What in the world is electricity?
