The bottle cap challenge: because it's been a while since we had something to watch to satisfy the boredom of sitting on the tube/hitting the 4pm office lull/scrolling through Facebook at 11.38pm when your brain is refusing to succumb to sleep.
Every time an internet-based challenge comes around, we find ourselves asking the same question - why do we love them so much?

Whatever the reason, like the #inmyfeelings challenge, the bottle cap challenge has captured the imagination of civilians and celebrities alike.
