The Lethal Force of Lawnmowers - Mythbusters - S09 EP02 - Science Documentary

Is it just me, or Jamie is smiling and laughing much more than in the earlier episodes?

The beginning of the end of mythbusters that we all love.

I love seeing this episodes, the storytelling it's top notch. You can tell they've been doing this for 10 years (both the hosts and the BTS team).

46:25 This is actually what's the most dangerous, rocks flying away much less so. And it happened to a colleague of my father many years ago. He was standing a good distance from a lawnmower that hit a rock, making it fail with a blade-off incident. The blade hit him right in the chest causing near-fatal damage and it barely missed the heart. He miraculously survived the incident thanks to a family member who was an off duty ER doctor, who happened to be there and performed vital steps. In summary: always stay far away from lawnmowers, no bystanders, no children!

This episode really highlights the budget cuts they had to go through.

God I love mythbusters! You are doing the world a service!

I kinda prefer the old backfround music from the older seasons, this new one just feels like the show trying to be "hip and cool with the kids"

Thanks for uploading those!

I'd trade all these fancy slomo effects to have CGT back.

46:22, I experienced a comparable incident involving my lawnmower, and I am deeply grateful for the preservation of my lower limbs. Incidentally, the blade remains unaccounted for.

My home stereo from 20 years ago was powered by a modified welder and a car battery acting like a giant capacitor, managed to squeeze 3000 watts RMS outta two excellent cheap 760 watt car amps by adding giant heatsinks to handle being overloaded. Had to run around manually adjusting power in and out lest the battery boiled or things caught fire, but when I cranked up the volume most people worried about the house collapsing on them. :)

Having worked as a landscaper I can tell you how dangerous debris and mowers could be. One time I was using a new mulcher with a big Kawasaki engine on and I hit what must have been a rock which flew out and hit a fence behind me, there was a bang I heard from the mower when it hit and when it struck the fence, to me both sounds happened at the same time. I went to check the fence and it had big dent in it where it hit, as if it had been hit with a pickaxe. It was a proper, solid wooden fence as well, thick like wooden decking. I must have been around 25-30 yards away from it, so that’s some speed and force. Nowhere near the damage a handgun would have done but very nasty all the same, I’m glad that didn’t hit me!

There is a crucial methodology flaw with lawnmower test. What was the weight of the rock that flew out of the lawnmower with the speed of 400fps and just how far was it able to travel? Initial speed of 400fps doesn't necessarily interpret to your neighbor being "shot" with a rock while in his living room. Air resistance and uneven shape of the rock begin to play important part at these velocities. The only conclusion that could so far be drawn is - definitely don't stand next the side of the lawnmower which had its stone guard trap door removed, as you will get seriously injured. Or worse. But as far as "my mother in law was shot in our living room with a rock that flew from the faulty lawnmower of my neighbor across the street" - I remain unconvinced.

i want the final scene of braindead re-enacted

39:06 the third guy behind Adam and Jamie is happy as hell

Man I remember seeing the update graphics for the first time on TV, really felt like a new era Edit: oh yeah, forgot the "new" intro, definitely prefer the old one

46:22 I love when they overdo that much, but that was scary as hell. Jesus christ. Great episode! Thx for uploading!

Adam is speachless

The rock may have the energy of the bullet but not be as lethal. For example, the recoil of the gun has as much energy or more as the bullet.

how far would the pendulum swing from just the pneumatic fired empty.. i recon some was due to the oomph of the air...
