As you type a querry into the Google page, it tries to guess what you are searching for. For example, if I begin to type in "juggling", a small pop-down menu gives me the options of "juggling balls", "juggling clubs", or "juggling tricks." I just now began typing in "how to make a boomerang" and when I got has far as "how to make a bo" it suggested "how to make a bomb."
