It looks like the usual tennis superstars are going to walk away with all the medals at this year's Olympic games — yawn. So to make it more interesting and unpredictable four years from now, perhaps the organisers of the Rio games should consider adding flaming tennis balls into the mix, and filming everything in super slow motion.
That's exactly what The Slow Mo Guys did with their high-speed Phantom Flex camera. But while soaking a tennis ball in gasoline, setting it alight, and smacking it with a tennis racket is inherently a stupid and dangerous idea — watching the results captured at 2500fps are downright beautiful. So maybe every Olympic event should involve fire in some capacity? [The Slow Mo Guys]
