It looks longer than that to me. I was bored at work so I pulled up a Google satellite image of the Moscone recreation center. If they are in the northeast corner of the park, the width of the dirt area appears to be a more than 50 feet. If the pizza box was tossed 25 feet into the air, that’s a distance of about 55 feet.
It’s hard to tell if that’s where they were, but anyway, just from the video, the width of the dirt area appears to be quite wide.
Besides which, I would guess a delay of 25 milliseconds is noticeable.
I believe the ball has more than enough energy to rapidly increase the psi of the coke bottle because of the low stretch nature of the plastic used. The moisture in the pizza would make a clean hole much more likley in the cardboard and the pinata is made to break in 1/2. Hitting the actual targets would not be a big deal even at 40 ft. They may not have hit each target on the first take but I doubt very many takes would be needed. I did a show once with the same producers and they never had us fake anything, they did like to use camera angles to dramatize things when they could.
Yes I have no problem believing it, especially if there are a few takes which ended up on the cutting room floor, so to speak.
Agree. I have a hard time believing that a baseball can go through a pizza box (with a pizza inside) and leave a perfect “Wile E Coyote” hole. My instinct is that a ball moving fast enough to just punch through the pizza box (without disturbing its path) would create a shockwave which would spread out and mess up the pizza quite a bit.
According to one site, the park has “three softball diamonds, one baseball diamond (mostly high school games).” The one they are on is the larger one so let’s assume it’s baseball diamond. High school baseball bases are 90 feet apart. On a google map, I held a piece of paper to the screen and marked first and second base. Then I rotated it and marked where I thought everyone was standing. From the video, the guy throwing things is probably on second base and Cain et al are probably 15 inside the dirt. Then I took a measuring tape and measured the marks, divided 90 by the smaller one and the distance I got was that Cain is 25 feet from the guy throwing.
I also measured the guy throwing things and, assuming he is 6 feet tall, he throws the soda about 14 feet above his head (2 of his heights plus less than a half), the watermelon only goes about 9 feet above his head (one and a half his height), the pizza 14-15 feet above his head (2 of his heights plus nearly half) and the pinata about 10 (a little more than one and a half his height). That puts Cain at around 29 feet distance from him to the pizza box at it’s apex, less for the other objects. If these numbers are close, that’s half the distance between the pitcher’s plate and home base (60ft).
Also, if you slow the video down there is quite a delay between the ball hitting the pizza and the sound from it. The pizza gets hit and rotates 90 degrees before the sound is heard. I really didn’t expect that to be noticeable on video at that distance. You don’t notice it in life or at full speed video at that distance, but it’s there in slow motion. There is also a delay on the other objects although the soda bottle seems to have the least delay, probably due to the spacing of frames in relation to the audio.
I disagree, I think a 40 ms delay is quite noticeable. Did you watch the Babe Ruth video I linked to? Do you agree that there is a noticeable lag between the bat contacting the ball and the “crack” sound? Do you agree that the camera seems to be behind the third base line but in front of the stands? Do you agree that the microphone is probably in the same place as the camera?
I wouldn’t be surprised if this weren’t on the show. Here are some clips from tonight’s show and they don’t contain it. Since the two Mythbusters appear in the Paxti’s charity video, I assume they’re involved with it. The “52 Weeks Of Giving” charity hosts pizza parties for the organizations they support. There is a Paxti’s at 3318 Fillmore Street, one block away from this park. It could be that everyone was there for the charity pizza party, they take some kids and film some tricks (or create a fake viral video) and it won’t necessarily appear on the Mythbusters TV show.
I judge the distance by the thrower being several feet from the grass, that puts him close to second base. Look at the google map and you’ll see. When the camera pans left to the mythbusters and the kids you can tell they’re well inside the dirt, I’m guessing 15 feet from the grass. Measuring the bases on google map and assuming they’re 90 feet apart, then measuring where I think they’re at in the dirt, I get 25 feet, and that’s rounded up.
On slow motion the delay is very noticeable. I don’t think 40ms is noticeable at full speed. I can’t even judge the moment of impact without slow motion. I can only judge the moment of visible results.
Yeah I saw the lag in the Babe Ruth video. I have no idea how far away the camera is.
Yeah, I can see this video as something done completely separate from the show. It may not even get a mention. Who knows? I hope it’s addressed somehow, though.
That camera is much further back than you seem to think, zoomed in. Since cameramen wouldn’t be allowed on field, I would guess that it was either in the dugout area (unlikely) or in the front row of one of the sections. More importantly the audio is probably from a separate boom mic that could be anywhere in the stadium, so that would create the delay. See my previous link to the NY Philharmonic.
Okay - I get it now. In fact back in post #152 I wrote (bolding/italics added):
Even though I wrote that myself it wasn’t clicking with respect to what you were saying even though it should have. Obviously the third term changes the absolute value of displacement in a given time period for each object but not the relative distance between them. And that’s regardless of whether the acceleration is due to earth’s gravity, the moon’s gravity, no gravity, etc. :smack:
Assuming that’s all true, the same reasoning would apply to the Barry Bonds video.
To get a better handle on the “baseball” argument, I did a Youtube search for little league home runs, on the theory that such plays are usually posted by amateurs with videocameras, i.e. the sound is being recorded at pretty much the same place the video is being recorded.
I chose it because the parent making the video turns the camera from home plate to the outfield after Ezra hits the ball. You can see Ezra rounding first base. From the change in angles, it’s very clear that the camera is quite close to the plate – perhaps 35 feet.
Anyway, there is a noticeable delay between the moment Ezra’s bat strikes the ball and the moment you hear the sound of the bat hitting the ball. Which is consistent with my experience – such a delay is noticeable.
Nothing - it wasn’t part of the show. But they did show Cain throwing needles at sheets of glass. He got one needle up to 113mph and one of the needles shattered into a bunch of pieces.
You could tell the shattered needle was faked cause the gravity was all wrong and plus I think he’s got some kind of deal with a sewing company.
When they were doing prelim stuff measuring the speed of thrown baseballs, he was throwing twice as fast as Tori (around 90mph I think) and it looked like he wasn’t even trying. He can sure throw a ball…and a needle for that matter.
Every time they pan left to show the mythbusters or the kids, except on the pinata shot. After they ran forward to check the pizza, it seems they went farther back for the pinata throw.
The largest diamond in the northwest corner, the same and only one I’ve mentioned in this thread.
Which proves…? There is no information to be gained from that video. My Barry Bonds video may have been a bad example, but… it’s not up to me to prove the sound lag at 29 feet or however far.
Anyone else see a lag between the ball is hit and the sound reaching the camera in that video?
I was going to post a couple of little league videos which are obviously from 100 feet away or more in order to illustrate how you can’t see/hear any audio lag even at that distance, but I guess it would be pointless if you notice a lag in that video.
I don’t hear a lag here, either. And Youtube videos are kind of crappy when it comes to this. I’ve seen a lot where the video and audio don’t quite match up exactly, so even if there was a lag, I wouldn’t take that as a sign of anything.
I’m a bit disappointed there was no resolution to the video on today’s episode.
