Mythbusters: "Fireball Stungun"

New episode tonight:

From Wikipedia:

Does pepper spray + flannel shirt + stun gun = massive fireball, per CSI?
Can fireworks really launch a person over a lake?

The second one sounds a lot like the soda-bottle rocket from a few seasons ago.
 
I bet the fireball one doesn't work (not sure they'd do the myth otherwise), but I really want it to.
 
Does pepper spray + flannel shirt + stun gun = massive fireball, per CSI?

If I'm not mistaken, that's from the CSI episode where Adam & Jamie had a cameo. They were seen observing as the CSI team used ballistics-gel dummies to test how the fireball incident might've happened. So this is making it a two-way crossover! Heck, I'm surprised so much time has elapsed between them.

(In the CSI episode, they found it couldn't happen with conventional, modern pepper spray, but the officer in question had used an older, alcohol-based type because his girlfriend had taken his police-issue spray.)
 
On youtube they have a video of guys propelling themselves on a vehicle powered by mentos and coke zero and all I could think was "future Mythbusters episode". The only thing that might get in the way is that the results actually looked very reasonable.
 
I don't have to see the peisode to know the answers to these:

No

&

No

With a "maybe it'll start smoking" to the stun gun myth. And if they increase the voltage, the shirt will probably catch fire.

Didn't they already do something like that?

That's what happened in the CSI episode. "Fireball" is an exaggeration.
 
Fireball stungun: This turned out about as I expected. It seemed pretty plausible when it was done on CSI. The one thing that seemed odd to me was Adam being surprised that the police-issue pepper spray didn't work, because a key component of the CSI episode was that it wasn't police-issue spray, and the CSI team specifically determined that police-issue spray wouldn't combust. But that proved a minor issue, since the Mythbusters did get around to testing a variety of different sprays.

And the end result seemed pretty straightforward. High-voltage ignition source, flammable liquid, flammable fabric, oxygen atmosphere being a given -- it would've been surprising if it didn't combust.

In fact, it makes me wonder if it's a good idea to design tasers in such a way that they have sparks generated. What if the suspect has spilled alcohol or turpentine or something on his clothes?

Adam making his own shirt was an interesting touch. You never know what skills these guys will pull out of their hats next.

The "Jamie's-eye view from inside the hazmat suit" shot was a cute touch.

In the gratuitous last bit with the flamethrower, that was an odd human analogue they used -- basically a skeleton made of rebar. I wonder what that was originally. Something for a commercial? An art project? (Adam's line about Grant having a whole staff of such robotic servants at his castle was kind of creepy. I mean, that would make one scary-looking robot army.)

After seeing a CSI clip in Mythbusters, I've realized something: Nick Stokes reminds me a bit of Tory Belleci.


Fireworks launch: The myth was so vaguely defined that it would've been pretty much impossible to give it more than a Plausible. But the vagueness gave them a lot of room to play around. The different designs they came up with were interesting. I think the problem with Grant's chevron-shaped design was that too much of the thrust was wasted perpendicular to the vector of motion. I understand the principle of using that to stabilize it, but there just wasn't enough forward thrust left over. As for Tory's, the X-Wing/Babylon 5-Starfury approach looked awesome, but I don't think the struts were strong enough structurally, so the whole thing just broke apart. I loved it, though, that the rocket itself went nowhere but the pilot was flung a considerable distance. That's something Chuck Jones never thought of subjecting the Coyote to. :lol: (And did anyone else notice that Tory's Mini-Buster had its face drawn to look kinda like Munch's The Scream?)

Kari's design was intriguing and counterintuitive. I'm not sure all that downward thrust against the neck and shoulders would be particularly safe, though. And it's ironic that the prediction Grant made about the small-scale design -- that it would be too back-heavy and just go into a spin -- didn't come true for the small-scale but did for the full-scale.

I think their rationale for calling it Busted was reasonable. True, if they'd tweaked the design still further, fixed the problem of the feet lifting up, they might've been able to get a fairly long flight. But as they said, they had a lot more resources, time, and expertise to apply than the mythical German Raketenmann, and even so they weren't quite able to make it work. So some guy acting on a whim and trying to pull this off would probably have sent himself only to the hospital or the morgue.
 
Meh episode. They need some good myths to test.

Kari, somehow, keeps getting hotter and hotter in contrast to all natural laws. I think she's not human.

Well, we know she's not one of Grant's robots, else she would've been programmed to protect him rather than using him as a human shield. :lol: Besides, if he could build robots that looked like that, why would he settle for a castle staff of terrifying rebar skeletons?

See, this is the part of their process where I usually have a problem with them. Given how it went, I'd have to argue Plausible. Why?

-They did the math, and the number of rockets used was sufficient to lift that much weight and cover the distance. It's not SMART, and very likely not even a little SAFE, but NOT impossible, or even unlikely enough to be busted.

3 people each came up with one idea, and tested it once. Doesn't mean that a 4th person wouldn't have had a different design, with different results.

To make it even worse, Kari's idea *almost* worked. The dummy couldn't hold on, and was lifted up, which caused Grant's prediction to come through. A real person would have probably laid down stomache-first, and head uphill on the ramp, so could have held onto the board, as well as added more weight to the front of the rocket sled, which may have stabilized it.

With a little more time, they could have adjusted things and probably made it at least launch decently, and then just a matter of whether the rockets could carry the weight over that whole distance required.

They didn't use any more rockets than the myth stated, they didn't use any special parts, and even used things like skateboards because they assumed the guy would be the German version of a redneck (probably rightly so), and just used stuff around the house.

If the math worked, didn't have to up the number or power of rockets, and the materials were all common, seems like it could have been at least plausible. They throw around "busted" far too much, and not always justified. Not safe to try, and guy would have probably been hurt, but going into a lake, could have survived it as long as the initial launch worked out alright...
 
^But that's the question: how was the myth defined? The myth, as stated, wasn't that it was theoretically possible to do this. The myth was that some German guy with too much time on his hands actually did do this, using makeshift materials, and achieved the stated result on the first try. And they satisfactorily proved that that was simply unbelievable. While it could theoretically be done, it would take far more precision, time, care, and resources than the individual in the myth had.
 
And THAT'S the big problem with the show. They make their own definitions up, then declare them indisputable requirements for the myth. Kari specifically did that in this episode. Early on she admits she's guessing and just picks a number out of thin air (I think it was in regards to the guy's weight, which was well over the average, especially for Germans). Later in the episode, that's become an absolute requirement.

They don't test actual myths. They take a myth, contort it, and then test it. Then their results are based not upon the actual experiment, but whatever conditions they set for it -- often making shit up at the end. It's all but random.
