Have you ever mixed milk with Airheads?

Alvin Kamara decided to issue a challenge to fans on Christmas day—and the prize? His highly-coveted "Watermelon Zoom" Airheads candy. Kamara got his own flavor after the candy maker noticed the Saints running back was always eating them on the sidelines.

The flavor isn't available in stores yet, but a few people have been lucky enough to get their hands on one. Kamara gave people the chance to pick them up around the city on Christmas day, but there was a very unique catch.

As crazy as the challenge sounded, people actually showed up to claim their Kamara Airheads!

Some even traveled from across the country!

There is no word on when the custom Kamara Airhead flavor will be available to the general public, but in the meantime, be on the lookout for your next chance to score your own "Watermelon Zoom" by following Kamara on Twitter.
