Can you really split a bullet with a sword? The Slow Mo Guys tested the logistics of such a feat, but using a safer approach that involved a giant super-sharp knife and a pellet gun firing tiny projectiles to minimise any undesired results—like one of them getting hit, or their incredibly expensive slo-mo camera getting destroyed.
It took some trial and error to get the ideal results, like pointing the pellet gun at the knife at point blank range. But the 28,500 frames-per-second slo-mo footage they managed to capture shows a pair of balloons being punctured and popping at nearly the exact same time, by the same projectile. [YouTube]
