An explosive prop being built for a gender reveal party accidentally detonated and killed a father-to-be in New York state, authorities said Monday.

The prop under construction wasn't even going to be the final product to be used for the gender reveal, but just the prototype, Trooper Steven Nevel told NBC News.

"It was just an innocent prop for a gender reveal that went horribly wrong.".

With the rise of social media, more and more couples have opted for elaborate stunts to reveal the gender of their unborn baby.
