Sounds Dangerous (I'm In): Cutting Things In Half With Rocket-Powered Knives

January 9, 2017


This is a video of the Backyard Scientist using homemade sugar rockets to propel knife blades down a graphite lubricated track to destroy toys, a raw chicken, a chuck roast, and a variety of fruits and vegetables at speeds up to 150MPH. Apparently it's a small-scale recreation of a bit from Mythbusters. Although, is this really even backyard science anymore? I feel like this guy has gradually moved from backyard science to backyard accidentally killing or maiming himself or a friend. Still, props to his buddy Riley for being willing to stand at the end of the track with absolutely zero protective gear on. Now I'm not necessarily saying his balls are bigger than mine, but I am saying earth is actually one of Riley's nuts and we all live on it.

Keep going for the video.

Thanks to hairless, who refuses to shave with a rocket-powered blade even though I've suggested it twice. Come on, what's the worst that could happen?

    Where I grew up we called people made explosives and blew up their back yard "dumbasses".

    This guy has consistently failed to live up to the name "scientist". If he's following any scientific method he never bothers to show us his pieces in peer-reviewed respected journals. He doesn't explain the data. It's just "I think we can pull this bullshit off" and then "blammo" he pulls it off, more or less.

    The fact that the knife only went straight through the chicken tells us that most likely he didn't have the blade at a good true center. Or... the bevel on the edge wasn't even. At 150 mph symmetry would make a world of difference. And he didn't repeat any particular experiment other than "does the rocket sled work" which was pretty likely from the get-go.

    Bottom line, this guy needs to step his game up or pick a more relevant name like "backyard dumass".

    "Hey, lets heat this knife to red hot and then try to grab it out of the channel within seconds and see what happens."

    I seriously laughed way too hard at that part....

    I'd seriously call the cops on these idiots... Even with the utmost safety procedures, Mythbusters still accidentally launched a cannonball into a residential neighborhood, I give these jackasses less than a year before they end up maiming either themselves or someone on the other side of that fence.
