Some events happen so fast that it's over before you can even react. Super high frame rate recording enables you to see the previously unseeable - including points of ignition and the atmospheric distortion caused by shockwaves and speeding bullets.
Yeah... it's cool.
If ever there was an opportunity for 'Wow!', then you can expect to find it here. Sure, it's science, and engineering, and all those things. And, it doesn't matter if you want to analyze the action of a firearm for precision adjustments or examine the launch of a rocket. When you see it play out in slow motion, you'll have a smile on your face.
