This is a video of Destin of Youtube channel SmarterEveryDay and friends pitting a variety of different weedeater grass trimming lines against each other in a single elimination tournament, filmed at 28,000 frames/second. Destin says for about every two seconds of footage shot, they had about a half hour of video to review. Now that is some serious slow motion! So, what does happen when you pit two weedeaters against each other? The sidewalk doesn’t get trimmed, my dad gets mad at me for breaking the weed eater and I don’t get my allowance this week, that’s what.
