YouTubers jump off canyon on 'insane' swing

YouTube phenomenon Devin Graham has released a video of "the world's most insane rope swing ever" - which takes place over a canyon in the US.

Graham, aka devinsupertramp, asked some of his fellow YouTubers to join him in the daring stunt, which involved a 400-foot free fall through the canyon.

One of the daredevils who took part, vlogger Shaycarl, tweeted afterwards, "About half way down I remembered there was a camera on my face and I should try to look like I wasn't terrified!"
