  • Hey there! This one was a lot of fun to make! Ever since the lawn mower video I've been wanting to do this, and I've been working on it all week. Thank you for those of you who support us on Patreon! You bring stability to my family's life. My goal is to be a light during this time. I know the world is a bit crazy at the moment. I wish you and your family peace and love. Spread the love and help others where you can. Look for the positive stories of people coming together in unity and try to amplify them. There's a lot of disinformation at the moment so if you recall what we learned together in the social media disinformation series, think twice before you share something! Warm Regards, Destin

  • 4:40 my weed eater has a centrifugal switch, so as the line gets longer it auto locks, but if it shortens the lock disengages and lets more wire out

  • Weed eater obstacle course in slo-mo is like a dogfight between mankind's inventions. Ask the fence with a thousand yard stare, it's seen some ****. I was also impressed by the slow-mo of trimming the grass. It keeps springing up only to be pummeled again, and eventually this cuts it down to the correct level. I should stop anthropomorphizing the objects in this video, it just sounds like a low quality movie script Hollywood would pounce on in a heartbeat. :D

  • Wow! I never guessed that there was that much tension on stationary objects when the weed-eater line connected with the objects. Now every time I use that tool I will be thinking of how it's banging against walls, fences, posts, etc. If you ever do this again how about recording how it looks when the line comes into contact with various wall typess, street signposts, and the sidewalk.

  • I wouldn't say the torque is function of length of the line. More likely the longer the line the higher the torque needed to reach certain speed. One could then argue that torque is function of speed which is correct but the torque was not measured. The speed was derived from the sound so the speed is function of length of the line. Which is in line with the torque being the same with more resistence to movement caused by the lengthening of the line causing lower speed.
