Move over extreme sports, ‘extreme phone pinching’ is guaranteed to deliver an adrenaline rush like never before. Warning: It’s not for the faint-hearted.

The nerve-wracking new challenge has people dangling their expensive smartphones over all sorts of dangerous places like toilets, drains, balconies and even high cliffs. There’s only one rule – they’ve got to ‘pinch’ their gadgets using only their thumb and forefinger!

The bizarre, rather pointless trend was apparently started by Twenty One Pilots, an American indie pop band. They posted a YouTube video of them performing the phone pinch stunt and it spread like wildfire across various social networks, garnering over 300,000 views. Before long, the hashtag #extremephonepinching became a thing and people began tweeting videos and pictures of their own attempts.

Some of the gifs and videos show people holding their phones over gaps in drains, while others dangle them over balconies several stories high. A few have held them over cliffs, rivers, famous bridges, and even Niagara Falls. One girl tried the challenge when she was in a hot air balloon. “Almost #extremephonepinching on a hot air balloon but my mom yelled at me,” she tweeted.

The trend seems pretty harmless because it seems that the forefinger and thumb do a pretty good job of holding gripping a phone. But there have been a few accidents, like with Twitter user @samtolliver1 who posted pics of his broken phone with the caption “when extreme phone pinching goes wrong.” And one person was dumb enough to hold their phone over a toilet using a long pair of tongs. Needless to say, it fell right in!
