Doctors are warning that the latest social media fad could be fatal. The “Tide Pod Challenge” has taken social media by storm but the craze could be extremely harmful to humans. Teenagers have been posting videos of themselves chewing and gagging on the small, colorful detergent pods and daring others to follow suit. However, the pods, which contain ethanol, polymers and hydrogen peroxide are extremely toxic and can make people very sick if consumed. The fad has gotten so serious that Tide has enlisted New England Patriots tight end Rob Gronkowski to cut a PSA urging people not to poison themselves.
