      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

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

      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.

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

    9. yoni591

      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

    17. 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.

    49. 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 ;-)

      ...that's not a "WEED EATER"..."WEED EATER" a brand name of "LINE TRIMMER" machines, this looks like a "STIHL" brand...same as when people say "ROLLER BLADES"...that's a brand name among many...they're real name is "INLINE SKATES"...

      Cutting grass suddenly looks so gruesome. The grass bits t]flying around look like blood spattering out when you shoot a zombie or something.

      you've got a white clover issue

    75. Jarod Doust

      I'd like to correct you my theory on why the tips of the weed eater line are still curved at full speed is because the tips make first contact with other objects, it takes more beating from the outside which causes it to bend and form memory in the line.

      I've found if you tilt a weed eater to the right slightly it shoots all the grass and rocks or sticks away from you instead of twords you

      This channel is so awesome. We get to see things that we would otherwise never have the opportunity, but also because it is presented in a professional way as opposed to just a couple guys playing around.
