Cool baseball gender reveal

A cool video has emerged from the United States of a couple revealing the gender of their baby to friends and family using a baseball.

In the clip, which was filmed on June 7, the mum-to-be throws a special baseball to her husband who hits it with a bat and releases a cloud of blue powder into the air, indicating they are expecting a boy.

"My wife and I are expecting our first child. We wanted a fun way to do the gender reveal for everyone and decided to go the baseball route," the filmer wrote online.
