A family in Alberta recently discovered more than just their baby's sex when they threw a gender reveal party recently: they also learned how to start a wildfire.

Alberta Wildfire says the recent blaze was started by an "exploding target," a popular gimmick used for dramatic gender reveals but with a fiery side effect.

According to CTV News Edmonton, one person has been fined $600 for starting the fire, which grew to be over half the size of a CFL football field.

A total of 10 firefighters were needed to put out the wildfire, CTV said, which happened on May 31 near Fort McMurray. It's reportedly the third fire in Alberta this year to have been caused by an explosive target.

Alberta Wildfire reminded residents via Twitter that anybody using an explosive target must have written permission from a Forest Officer beforehand.
