From eating cereal out of someone’s mouth to the famous silhouette challenge, we have seen how quickly TikTok trends can go viral.

But even though some challenges can be fun and fairly safe to take part in there are others that are extremely cringey and even dangerous.

One of the earlier challenges on the video-sharing app was called the ’skull breaker’. This would involve two people kicking the legs from under a third person, making them fall over on their back.

What started as a ’funny’ prank led to some serious injuries and in some cases, the police had to get involved.

According to the BBC, two youngsters were charged with aggravated assault after taking part in the dangerous challenge. Parents were told not to let their children take part in it and eventually TikTok said they would remove the content completely from the platform.

Here are some other challenges that should have never become a thing.

Testicles taste buds challenge

We are starting this off on a really weird note… In this challenge men would be seen dipping their testicles into Soy Sauce, checking if their testicles have a sense of taste.

According to reports, the bizarre science experiment started after a TikTok user came across an article about a 2013 study that determined mice have a form of taste receptors in their testes. And just like that men wanted to see if their testicles had the same.

The cereal challenge

In this challenge, people would basically use someone’s mouth as a cereal bowl by laying them down and pouring cereal and milk into their mouth.

This challenge could easily lead to choking especially once the person started laughing with a mouth full of cereal while laying down. Also, it’s a bit disgusting.

Teeth whitening challenge

There have been a number of teeth whitening methods that came from TikTok but one that caught the attention of most dentists was the one that featured hydrogen peroxide.

A user was seen adding 3% hydrogen peroxide directly onto their teeth, defending her actions by saying that most whitening strips included peroxide as the main ingredient anyway.

Dentists were quick to warn users against this ’hack’ by explaining the negative effects of bleaching your teeth. “Prolonged bleaching with these high concentrations of hydrogen peroxide, especially when used multiple days in a row, can lead to highly irritated gums and sensitive teeth,” dentist and Waterpik spokesperson Chris Strandburg, told Health.

Kissing a friend challenge

This challenge gave us a serious case of third-party embarrassment. A user would randomly attempt to make a move on their best friend by kissing them. The whole thing would be awkward unless the best friend kissed the user back.

Toothpaste spit challenge

Just when you think things cannot get any more bizarre someone comes up with this challenge. In this one users (usually women) are seen brushing their teeth and spitting it out, which seems like a strange thing to document.

According to HITC the challenge is actually x-rated, as the white toothpaste liquid is actually supposed to resemble semen.

The song that goes with the challenge is Sex Talk by Megan Thee Stallion, and girls are seemingly doing the challenge to imitate explicit videos, which is definitely concerning since TikTok is full of impressionable young users.

Garlic hack

One of the latest home remedies for curing a blocked nose on TikTok involves stuffing garlic cloves up your nostrils and keeping it in there for 10-15 minutes.

One of the first people to give this bizarre trend a try seems to be the TikTok creator Rozaline Katherine, who posted a now-viral video of herself with garlic in her nose.

In the clip the fitness trainer can be seen stuffing two cloves of garlic into each of her nostrils.

“Saw on TikTok, if you put garlic in your nose it unclogs your sinuses,” the text in the clip read.

She kept the cloves in place for around 10-15 minutes before removing the cloves only for her nose to start running.

Experts do not believe that stuffing garlic in the nostrils will relieve a stuffy nose, but they can understand why people would think it does because once they remove the cloves their noses usually start running which makes it seem like it worked.

As much as TikTok brings some much-needed entertainment to users of all ages, some of the challenges may not be appropriate for younger users.

The platform does however offer a restricted mode that tries to limit age-inappropriate content from appearing for children. Parents can set it up in Settings > Digital Wellbeing > Screen Time Management.

Adults on the other hand, will just have to cringe their way through the For You page.
