When it comes to baby gender reveals, some are out of this world. For example, a couple sent a balloon into space to find out if they were having a boy or a girl. With the help of a high school space group, they launched the balloon into the sky, and when it burst, they got their answer! Couples have used chainsaws, exploding baseballs and tattoos to help share the news. One couple even enlisted the aid of Bill Murray to help reveal the sex of their unborn child to the world.
