Holm flaunts inner-MacGyver with 'potato gun'

It's amazing what one can do with a potato and a can of hairspray.

In a Saturday Instagram video, former UFC bantamweight champion channeled her inner-MacGyver to create what she dubbed a "potato gun."

Judging by the concoction's (literally) smashing success, it's safe to assume this isn't Holm's first stab at homemade weaponry.
