Why NASA Uses Explosive Bolts! You don’t unscrew a rocket you blow it up! 🚀💥 In aerospace engineering, speed is everything. When a rocket needs to ditch a spnt fuel stage, it can’t wait for a mechanical latch to open. This video explains the science of frangible nuts (explosive bolts). These bolts are hollowed out abd filled with a small pyrotechnic charge. On command, they shatter along a pre-weakened line, allowing for instant, clean separation in thr vacuum of space. It’s one-way engineerin
