Weeks. Months. Potentially years.
We've no idea how much time it's taken YouTuber HiJosh to build up his frankly phenomenal object throwing skills, but we'd hazard a guess that it's not something that comes naturally.
The focus of HiJosh's first video compilation will be familiar to anyone who's fallen into the clutches endemic procrastination: despite a deadline looming large, the best possible use of your day involves throwing a depleted Coke can into a bin from across the room. Then, with an overhead shot. Then, while filming it.
Some of the throws in HiJosh's video defy belief, while others must surely be fluke. Some are crying foul, suggesting that the prankster is mixing real shots with fishing line trick shots that have been reversed and edited - but it makes for compelling watching all the same.
We're off to spend to the rest of the day hurling sugar cubes at cups of tea from across the kitchen. Send us your best attempts.
