The US company introduced the Carolina Reaper Madness One Chip Challenges back in 2016 and 2017, and two years later the super hot snack - sold as just a single item in a small red coffin shaped box - is back for another run.

The Carolina Reaper Pepper which dusts the crisp is considered the world's hottest and it is loaded with capsaicin, which triggers messages of pain and heat - which in turn can lead to vomiting and shortness of breath.

Although the chip isn't quite on that level, it's still proven almost impossible for customers to finish.

It can only be bought through Paqui's website for $6.99 - or $59.90 for a 10 pack - while punters are encouraged to upload photos or footage of their attempts.
