1Underboob Pen Challenge
Those who are most "talented" can grasp pens, pencils, makeup brushes, bottles of lotion and even flowers with their breasts. The revealing snaps are usually accompanied by the caption, "Pass the challenge to prove you're a true woman." (Source)

But things don't always go so great. Fourteen-year-old Skylar Fish suffered severe head injuries, a brain aneurysm and damage to his eye socket, prompting serious questions as to the potential risks associated with the "challenge."
3Extreme Phone Pinching
A few tamer examples of the craze include dangling your phone over a balcony or in the gap of a sewer drain, although some go more daring lengths to show how risky they're willing to be with their precious gadgets.

The challenge involves filling a condom with water and engaging the services of an assistant to hold it above the participant's head. It is then gently dropped onto the challenger's head and should wrap itself around the person's face and neck but remain intact, with no water being released. The condom often has to be broken to separate it from the wearer, leaving the challenger drenched.
At least there are a lot of kids using condoms — that's good news to me.

5Belly Button Challenge
Don't despair if you come nowhere reaching your waist. It appears that someone's ability to achieve the belly button challenge is not down to one's tiny waist, but rather a range of factors including flexibility and arm length. (Source 1 | Source 2)
And he wasn't the only one — there are hundreds of videos online of people performing these stunts to various degrees of injury. It seems the point of the challenge is to spray a small amount of flammable liquid, like alcohol or perfume, on an area of the body and light it on fire. Many of the participants appear to be teenagers or younger and accidents happen if too much liquid is spread or they are unable to extinguish the flame quickly enough.
The images, bearing sayings like "I love it when ... guys notice my bikini bridge" and "if your girlfriend doesn't have a bikini bridge why are you with her" are in the style of "thinspiration" posts that circulate on social media and pro-eating disorder websites.
The hoax resulted in thousands of tweets, as well as community posts generated by the pranksters on Buzzfeed and CNN (both of which have since been removed). It was quickly attributed to 4chan by reporters at The Daily Dot.
What started as an Internet prank can potentially do lasting damage by giving people with eating disorders a dangerous new goal to obsess over, health experts say. Even if it was dreamed up by a bunch of anonymous Internet users, the bikini bridge is "a thinspiration members' dream come true," said Lynn Grefe, president and CEO of the National Eating Disorders Association. Spreading the images is as easy as "just passing it along" via a blog or social network post, she said. (Source)
The more coins you hold, the better your figure is. (The coins must be kept standing up as much as possible.)
Most participants in the challenge are women— some hold around 20 coins on a single collarbone.
There is yet to be any scientific theory to support the challenge. (Source)
