      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

      Watching what is otherwise a relatively rigid and stiff material impact wire and become so soft and gloopy was kinda nutty

    13. Ed Forbes

      Weed eater sounds like a description of me at 15! Here in the uk we call them strimmers. I prefer weed eater though!

    19. UmpikLumpik

      Is that sound also captured by the camera or it is post production thing? Thank you!

    20. Gregor Coetzee

      This is the most dedicated gardener I have ever seen.

    21. jamcdonald120

      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

    22. Stingrayray341

      Cool shirt. I’ve been by that store dozens of times.

      Bingo you do go right to left slowly walking sideways backwards

    26. Daniel Hale

      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

    27. Garrett Glass

      Nice clouds.

    28. Spydercolector

      The sound in slomo has to be fake right?

    29. timtrainage

      I don't know Destin, I think Project Farm did it better

    30. Coltyn

      This is like a horror movie for grass.

    31. Matthew Spotten

      I feel like this is a lot like getting your first oscilloscope.

    32. Lucas 'Ktulu789'

      17:37 Destin became Crazy Russian Hacker so slowly that I couldn't notice! Boom! I vas vattching the ad on anozher channnel like zhatt! BTW. It's the second time I watch this awesome video! Love you, Destin! I wish I didn't live in Argentina to be a Patron (without the government stealing 70% of the money).

      All the microplastics going into the environment, this video has convinced me to use a steel blade and not a plastic line for my whipper snipper!

    36. Dark Rose Genie

      VentriloMatic approves of this video!

    37. Fabian

      Maybe this system contaminates the environment and the soil with small particles of nylon. Think in the amount of gardens around the world.


      Weed eater in England we can them hedge trimmers bru

    39. HAUNEBU 2

      Friction happens I’mI don’t think that Weedwhacker’s powerful enough to do an effective test. Look up the strongest Weedwhacker’s I use an echo commercial type! it’s amazingly powerful

    40. HAUNEBU 2

      The string melts! it immediately heats up when it hits metal and wood in melts apart

    41. Ramon

      7:57 talk about leaving split ends...

    42. The Dominator

      What is this language where you call it a bloody ‘weed eater’

    45. MikeC19100

      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.

    46. Evan Fabri

      Booo to every weedeater that has ever been used. Atrocious noise pollution. Incredibly selfish to use one.

    47. Dancan799

      Sees title expecting some sort of chemical, sees a strimmer. Oh you funny chaps with your strange names for things

    48. Johnny Rep

      There is something so satisfying in watching the slo-mo chopping of grass.

    49. MaximalistTrader

      That string is trash.. it’s tearing the grass and not cutting

      WTF is a "weed eater"? It's called a lawn trimmer, or just a trimmer!

    53. Stevooo 1

      I was sad when Mythbusters stopped making episodes. However, today I found this channel and feel rejuvenated! This is internet gold for science lovers like myself

      When they are playing in slow motion, it feels like torturing small innocent plants.

    56. ToastedDoughnuts

      Did anybody else notice the smarter every day logo on the rotating part of the weed eater?

    57. yoni591

      Do you fake the sounds in slow motion footage? Cause i know slow mo guys do

    58. Noneyo Business

      Is a weed eater any way related to a weed whacker?

    64. JAW Media

      Hey I am not sure if what I was hearing was combustion cycle or not but if so. That engine fired 22 times in 1 rotation of the head. Granted it's a 2 cycle engine but still if that's true that is almost unfathomable

    65. Lukáš J.

      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.

      It’s called a whippa snippa

      1:04 come on! Finish what you started!

    97. Jeany Luisa

      I think that automatic cutting of the line is only smart for people who dont dislike plastic particles in their lawn. I never really liked those little pieces of line in our garden. If you want to make it look even more like science, measure things in millimeter ;-)
