The 24 hour challenge is just that - once nominated, you have 24 hours to upload a video of you doing something outlandish in your gitch, outside in the sub-zero cold. After your stunt, you must immediately thank whoever nominated you for the nomination, nominate 3 people and tell them they have 24 hours to complete the challenge. Lastly, you must chug a beer.
