Fashion viral challenges are increasingly present. Many initiatives run like wildfire through social networks every year, looking for adepts and daring to join them and share the images of their feat through the Internet.

In recent years, the 'challenge' have shown their faces and their cross, with proposals that are popularized by their solidarity or charity, as was throwing a bucket of ice water over in favor of the ELA -Ice Bucket Challenge- ; others for being pure entertainment, like the most recent Mannequin Challenge, and others really dangerous and in serious danger of death as was the challenge of the Blue Whale.

The 2018 started with a new danger circulating through the nets, chewing detergent tablets. As a result, we review some of the most popular challenges in recent years:
