Not a cartoon myth after all. Somebody on the fan site is apparently alleging that this really happened. But it's so obviously based on cartoon assumptions of physics. Adam didn't specify, but he's implying the skydiver survived, which is a blatant impossibility about on a par with jumping to survive a falling elevator (which they already busted quite spectacularly a few seasons ago).
As for the rest, okay, the first test did send the "girl" about two stories high, and that was with the deformation of the seesaw absorbing a lot of the energy. And then came Adam's scale test, which gave surprising results.
Although come to think of it, it's not that surprising that the "girl" flew higher than the lead ball was dropped from. It's basically the law of action and reaction. The doll had less mass than the lead ball, so if the lever (seesaw) transferred the ball's full momentum, it would've imparted a greater velocity and thus sent the doll to a greater height.
Still, she went pretty much straight up, so I doubt landing on the roof of an adjoining building is going to happen. Unless there's a mighty gust of wind or something.
The skydiver's camera suit is interesting. I can see why a camera operator shooting skydiving footage might have a need to adjust the speed of one's dive. What I don't get is why Grant and Tory had to jump at all when they weren't the ones in the suit. Sometimes this show goes overboard on having the hosts be the ones doing stuff rather than leaving it to the experts.
Not to mention the bungee jumps. Did they actually gather any data at all by jumping themselves? That was really just for show.
Jamie's heavy-duty seesaw is impressive, and a hilarious amount of effort to put into a seesaw, but if you have to go to such extreme lengths of engineering to achieve the result, doesn't that bust the myth right there?
"And yes, I do know what guts feel like. I've been on this show for years."
The bungee acceleration to terminal velocity was a good idea. I was thinking some kind of downward-pointing air cannon. Anyway, the full-scale test gave very impressive results. And I can see why the doll flew in an arc here rather than straight up and down. I mean, look at that monstrosity Jamie built -- that's not a teeter-totter, that there's a catapult. I think this result demonstrates more about Jamie's engineering skills than it does about the myth.
It also demonstrates how unlikely it is that the skydiver could actually land on the seesaw at all. However much they replicated the results, this myth was obviously a load of rubbish from the get-go. Made for a fun episode, though. I'd love to see more whole-team myths like this.
Oh, and that was a cruel shot at the end there, with the girl's little dolly falling to the ground. Ouch!
