For some reason, TikTok has become the unofficial home of all things weird, and the latest trend has seen people filming themselves downing food dye and seeing the effects on their body.
He initially started out doing a five day challenge. On the first day he shared a video of himself with a glass of blue food dye and water. He necks the drink, leaving him with bright blue teeth and lips.

He goes on to post an update every day.
Sharing another video, the TikTok user says: "Day 3 of drinking blue food coloring! Will I turn into a Smurf?"
Clearly starting to enjoy its effects, he pushes through. With his whole mouth stained blue, he shared another video captioned: "Day 8 of drinking blue food coloring! I might be turning blue..."
The real question here is what is he gaining from 'turning blue'? His skin definitely looks like it's tinged.
On day 10, he shared a video saying: "Number one, my pee has turned blue. Number two, my poop has turned blue too. Number three, I'm turning blue. My skin's blue guys and my hair is even turning blue. It's getting wild."

Although he keeps saying the food dye is 'harmless', TikTok has now marked the video as potentially unsafe, and his videos are now marked: "The action in this video could result in injury."
The NHS has advised that certain food colourings can effect the body, with possible links found to things like ADHD.
The website says: "Research has found a possible link between certain artificial colours used in food and problems with hyperactivity in children.

"All food additives - including artificial colours - have an E number, which means they've passed safety tests and are approved for use in the EU."
The food colours most closely linked to hyperactivity in children are different shades of red and yellow.
Others on TikTok have seen Colton's new-found love for food dye. One TikTok user, @datboykeiko has been trying it with green dye, captioning his first food dye video: "If this don't go viral I'm quitting TikTok."
And there lies the reason for the new trend. The thirst for attention is real, lads.
