      Robert subscribed then hit the bell. Be more like Robert. In all seriousness I was impressed by how quickly he came up with a well thought out, nuanced hypothesis without even a moment’s notice. Huge thanks to Robert. Also, a huge thanks to everyone who supports Smarter Every Day on Patreon at www.patreon.com/smartereveryday Thank you! Destin

        I would go for the triangle string. Redusing the noise is more important than how the cut is.

      2. Bradley May

        After seeing the 'slo mo' I must say the Aussie slang is bang on the money. We call it the: WHIPPER SNIPPER 🇦🇺

      3. Adam Williams

        When you did your experiment with all the different lines miss one big thing when you cut grass there's not tension on both sides of the grass blade

      4. Science For Fun

        Hey Destin! Nice video , The star shaped wire is more likely to have its corner cutting the grass than others. When it ripps ripping lenght here is edge of a regular hexagon as compared to triangle or pointy squares.

      5. Dylan Fuller

        In Australia we call them whipper snipper's i have heard grass scissors though

    2. Mixup 221

      Destin : weed eater Snoop dog : weed smoker

    4. Matthew Keogh

      I reckon the sharp sharp square is very useful for someone like Robet who spends all his time 'Weed eating'. If the wire doesnt create one disk then you have a slightly wider area of cutting potential. Let's say you want the grass at a level height. The slightly wider cutting area allows for greater up and down motion of the weed eater. Also you'll be cutting the shorter grass as well as the tall with the wider cutting area. This is my take on it but I am no physicist, engineer or whatever profession that is. Also STRIMMER is the most relevent name. The tool strims the grass, weed or other type of vegetation. A weed whacker implies it simply whacks weeds. Weed eater again implies it only "eats" weeds. Soooooo, Strimmer is the best name for it because it does not imply a single medium to be cut or imply the tool has the capacity to eat.

      There needs to be another video with Robert about some topic he likes! He‘s the prototype street smart likable guy 💪🏻👍🏻

    7. Ennovative

    8. Samuel Schiltz


    9. The Sluníčko.

      I can't believe you just invited a stranger into your garage just to tell him his weed eater line sucks.

    10. Max Chavez

      it is weed whacker

    11. Landon Laureano

      Here on Guam we call it "Bush Cutter"

    12. Memer9456

      I call it 'Weed Wacker.' 'Weed Eater' sounds, well, 'interesting' to say the least.

    13. Paeris Merriam

      Weed whacker. You whacker em. You don't eat em. Jesus christ...

    14. Marcello Novak

      god this video is so satisfying

    15. Stevooo 1

      I'm in NY and I've only heard weed whacker. Maybe upstate NY calls it weed eater 🤔 im in long island

    16. a meme duck

      destin: hmm i wonder which shape is best? weed eater dude: come, my child.

    17. Jose Castilleo

      We say weed eater in Georgia, but everybody talks with an accent so it comes out more like wedeeder.

    18. Chris Williams

      Its pronounced. We-de-der

    19. anna egan

      I say weed waker but it dose not mater what you call it

    20. Eddie Fantastic

      Weed whacker

    21. Jake Pin

      I ran a weed eater for a living through high school and worked trimming guard rails on the interstates in my early 20s and I can tell you Piranha Sawtooth is unmatched for trimmer cord.

    22. Levi Belrose

      we say weed whacker or whipper snipper in canada

    23. Maffoo

      We call them strimmers but I’ve never known anyone to own one. Probably cos everyone’s got tiny gardens here

    24. Tahoma

      The best is an old round wound bass guitar A string. Only used with a guard, of course.

    25. ZERO % Pointy

      Does it eat weeds? Does it actualy consume them? Or Does it strim? To explain string -trim. .

    26. BernardSilver

      Why is Robert's final scene not near the end of all your videos? A brilliant description of what all your viewers should do.

    27. Polly g

      i live in west australia and they have always been called a "whipper snipper" 100% serious id guess this is a rare case of the greatest coup in advertising when a object that many sell become known by the name you invented like band ais for sticky plaster or glad wrap for cling wrap thats batting 100 if you can do this

    28. Captain Rex

      It’s called a weed wacker

    29. Bick Snarf

      whipper snipper

    30. Tm_ IPOD

      We just call it a snipper in AUS

    31. MC Cheez Strings

      The big lez show taught me that Australians call it a whippa snippa

    32. That boosted bastard

      you should do a video testing the efficiency and if the line can effect it depending pn the shape and the drag it causes

    33. Jolujo 58

      Robert's got it going on. He should have been a materials scientist.

    34. Mr.Nerd3.14

      Okay so I’m from Michigan but I don’t call it a “ weed whacker”. The closest thing would be “weed whipper” but I drop the “-er”. I’ve always called it a “weed whip”

    35. Andrew Stewart

      Is the Weed Eater guy Casey Neistat in a few years?

    36. Erik Jarandson

      When the professional weed eater guy's cord didn't straighten out completely, I suspect that it's because he uses a more powerful weed eater. That might also require a stiffer and tougher cord than what's optimal for less powerful weed eaters. In fact, I strongly suspect that a much more complex and exhaustive set of experiments would be needed to say anything definitive about what shape of cord is best. Certainly, both density and stiffness would have to be isolated.

    37. Alexander Sillan

      Yeah in Australia it’s a whipper snipper as you see in green and a kid is a whipper snapper cause they are always running around quickly snapping at your heels

    38. Jonas Horlacher

      Sounds like a Honda Civic every time he starts it up

    39. Stian Solhaug

      I see your weed eater and raise you with my "Gresstrimmer"!

    40. Allen Reinecke

      String line trimmer! 😉

    41. WildHorse 5.0

      Could the aerodynamics of the line play in whether the cut is clean or not ?

    42. AG_ from _83

      Why am I watching this??? And why can't I turn it off?

    43. Tristan Sanchez

      I am a landscaper and I call them trimmers

    44. Crusades 1298

      Me : *living in high rise apartment* . . . Also me : "INTERESTING"

    45. Lock Picking Electrician

    47. Bighaverlegend 69

      *W e e d E a t e r*

    48. Sawyer Strombom

      You should try using blades instead of wire, it'd be interesting to see the difference.

    49. Anna Orzechowicz

      In Chicago we call it a trimmer...

    50. Hary Anwar

      it's all the same

    51. AcogR6

      Us in Puerto Rico call it “trimmer” since it trims grass and weed I guess....

    52. Sploopi

      7:00 IntereSTRING

    53. Busy Brain Animations

      I’ve always known it as the whipper snipper probably because I live in Australia.

    54. TaylorGH1823

      I’ve never once heard it called anything other than a weed wacker! I’m actually shocked right now

    55. TheMighty DR

      Ive always just used the round string......it last longer

    56. TheMighty DR

      I call it a whip. Or a wacker

    57. KyleRB Playz

      I grew up saying weed wackier cause I live in pensilvainya

    58. Carter L.

      "How can I save $2 once a year?" I don't know but I'm going to spend $100 to find out

    59. Dman20111

      I hope Robert's enjoying the content

    60. Ryan Goodhart

      its definitely weed wacker in nj

    61. 506 independent VIDEO

      1:11 no! as a british guy, "weed eater" is far too informal! you need to address it in such a way that you respect its power. call it a strimmer.

    62. Still Chill

      Australia: W H I P P E R S N I P P E R

    63. Michael Allen

      Weed Wacker fo lyfe!

    64. Brad Davidson

      Weed whacker in Canada as well. But there is a weed eater brand that we use to trim the grass.

    65. Brad Davidson

      Before watching this video in full you would have to assume the triangular line would cut the grass the best base on the point of contact producing less resistance. Interesting that it is tearing it up. Things that make you go 🤔

    66. Robert Armstrong

      This Robert guy seems pretty cool. Also, despite living my whole life in Florida I call them weed whackers. I wonder if it's because my dad grew up in Ohio.

    67. Mimo Slavich

      HA! They are in decimals of an inch, I thought the whole point of rejecting the metric system was because fractions are better than decimals.

    68. Christopher Cooper

      I call it a weed eater.

    69. Didge Wilson

      Aussie also call them whipper snipper

    70. Didge Wilson

      Aussie call them brushcutter

    71. Inder

      Thumbs Up spl. for Robert. He is cool man 👍🏽

    72. Helton Moraes

      I think this is unrealistic due to the grass blade being tensioned from both ends. Real grass blades are being "held from below", and perhaps the whipping effect on the loose upper part of the grass blade could make a difference in the way the blade reacts to being whacked. This and the possible whipping of the wire itself, if the vegetation is denser than just grass blades.

    73. Jakub Jaček

      why dont use aluminium line ?

    74. MixDatSalt

      I don't get the term "weed eater" haha It wacks the weeds, not eats them.

    75. Joel Gross

      I subscribe to your patreon. I really don't like affiliate links as they make me not able to trust the content itself. You used affiliate links to the string you recommended, perhaps you would have bought different string or made different recommendations without the affiliate link. It can even affect you subconsciously.

    76. Elijah Pearrow

      Echo speed feed head. 12 years lawn service. Definitely the best!

    77. mikenative

      I used to cut grass all day. The rounder line has less drag and can be spun up much faster which makes a big difference to the cut The square stuff has more drag and you can hear it in the engine RPM but will chomp through thicker material without breaking. One thing that wasn’t mentioned in the video is that the line is never usually has a freshly cut edge. It normally forms a taper fairly quickly. If you took the line with the inner core you may well find that it tapers down at the tip and provides a better cut after a bit of usage.

    78. Bodor János

      We call it "Motoros Fűkasza" in Hungary. (In English its called Motorized grass mower)

    79. Chase Daily

      I think your sample size was just too small and it was more variance in the blades of grass rather than the lines.

    80. Robador Martinez

      in spain its called "desbrozadora" lol

    81. Koraxis S

      It’s a whipper snipper in Australia

    82. The Atlas Joker

      Whipper snipper is the most Australian thing I’ve heard in a while

    83. Roger Milla

      Robert is the man of the situation

    84. Dario Lattina

      M8, it's a whippa snippa. I'll fight ya. Kind regards, Straya. 😂

    85. Purest Cancer

      Australia its Whipper Snipper thats how I grew up

    86. Adam Williams

      When you did your experiment with all the different lines miss one big thing when you cut grass there's not tension on both sides of the grass blade

    87. Trae'Vaughn Towner

      once it pulls it in since it is a square it is like slapping someone with a flat hand

    88. Mashroom

      Could you compare different gauges/shapes of line against abrasive surfaces? Us gardeners are really interested in how long a line will last. I usually go for a thicker gauge with a hardened core because I assume it will last longer. Interesting to observe the end of that line after its been used too....

    89. Peter Müller

      I only know the name wheat wacker and I'm not even from the US. Any chance that name is used in movies? I have no idea why I would know that term otherwise

    90. Luigge

      I call here in Brazil in literall translation "grass cutter"

    91. Borivoje Travica

      Nobody concern about that mount of plastic disposal, very small fragments.... In very short time that and up in us in many ways. This is must be band.

    95. Xeric

      That map is definitely not accurate at all I know for a fact that a majority of cities here in Canada call it a weed wacker

    96. azirul izwan

      It’s a mesin rumput.

    97. dendeanda

      Small engine mechanic here: Great experiment here but you have to consider what you’re trying to achieve in the end and for what application. 1) Do you want a clean/precise cut? A cut that takes less effort? Are you edging, clearing or trimming? Do you have time constraints for completing the job? What are you cutting? Residential or commercial use?

    98. Rooftop Voter

      All those blades of grass, crying out in unison.

    99. ihasarax

      We call it a weed whacker
