The cutest newest way to announce the gender of the new baby. It will seem like a plain black mug! Once you pour a hot drink in it, the magic black mug will slowly show the blue IT'S A BOY onesie. (Make sure to have a camera around to record the reactions as friends and family discover that the baby is a boy haha)
