70 mph in Switzerland
It's amazing he can stay upright with those bowling balls in his pants.

Teacher Fed Up With Students Swearing, Stealing, And Destroy
...not the state laws that govern it. Nice try, Bob.
So, you agree with everything I said then, you just think somehow the Ohio public school system defies the long ruling political majority and does it's own thing? Wow, you must think liberals have bowling ball size balls of steel.
This really sounds like a no child left behind kind of problem....some kids need to be left behind....some need to be behind bars.
The education system is. Nice try Newt .
Marble Machine - Triple Gears Lift
I think I figured out what went wrong, it's supposed to be "marble", not "bowling ball" wood machine.
Very nice. I had exactly the same design idea, but the modules in my marble wood machine were too heavy to lift.
7 Minutes in Heaven featuring John Oliver [from 2011]
Reminds me of that time back in high school, when I trying to feel up my crush during this game and later realized I had 3 fingers in her dad's bowling ball.
Hydraulic Press - Balls Crushed
What?!? No bowling ball?!? I'm insulted.

Good point. Example case is the bowling ball pendulum

There's a difference between knowing it's safe and feeling safe while doing it.

Biggest Bladder Stone Ever! GRAPHIC! Saved By Youtube!
OMG!!!! Think about that if she was human sized, 10 times the size it is! It would be like having a large bowling ball in your bladder! Now consider trying to PASS that stone....I just passed out thinking about it.
I'm astonished this dog survived to get the surgery...and quite pleased as well.
I'm awestruck at this video, and also pleasantly surprised Youtube watchers paid for the entire surgery...good on ya, people.
What Not To Get Your Girlfriend For Xmas
The topic of bad girlfriend/wife presents always reminds me of the gift Homer bought Marge for her birthday. Do you remember that episode?
He gave her a bowling ball, which doesn't seem romantic at first, but he had it custom fit and engraved... It was sized to fit his hand and engraved "Homer".
Using Science to Explain Homeopathy ;)
Neutron stars are bigger than bowling balls, and they ain't getting more squeezed.
I love it when crackpots get into scientific details, because they're so easily pulled apart.
Using Science to Explain Homeopathy ;)
Take all the neutron stars and i can bet that the resulting body is larger than a bowling ball.

Uhhh lady, there's black holes bigger than bowling balls... so how can all of the universe fit into... when only one will... but with...... what the.... ok i'm done. I managed 1.30 to 1.50, don't think i'm winning the pool.

You've ignored the fact that they did it inside, so there's also the pull of the bowling ball on the walls and ceiling, and vice versa! ;-)
I'm pretty sure we agree on all counts except how detailed one must be when teaching simple lessons.
It's not falsifying details. It's nonsensical to pose the problem so that surface irregularities are taken into consideration. Or the fact like in this video the feather started below the bowling ball.
It's a trivial 3-body problem. You can represent them by three balls, one of mass Heavy, one of mass Medium, one of mass Light. As long as Medium and Light start at the same distance from Heavy, Medium and Heavy will always hit first. You can run this test in an orbital simulator if you don't believe me.

Oh...so it's OK with you to simplify and 'falsify details' significantly by modeling the earth as a perfect sphere, but not ignore the mathematically insignificant and immeasurably small possible movement of the earth in some direction or another due to multiple immeasurably small gravities?! WHAT?!? ;-)
....Um...1 degree on earth is 111.2 KM, there's such a tiny difference (1 cm+-) they are in the same place for all possible measureable purposes, nothing like 1 deg apart. My scientific calculator won't give an answer, 1 deg * (1cm/111.2km) =0.00deg on it. (OK, it's not hard math...1/11120000 deg.) Because of this, yes, they WOULD cross the imaginary line, AND hit the earth at the same time by any possible measurement. If the smallest distance measureable is FAR larger than the distance they differ by, and the smallest time measureable is MUCH longer than the difference in time they hit, normal (and most abnormal) people say it's exactly the same.
And again...the experiment properly ignores any infinitely tiny immeasurable movement of the earth in ANY random direction for the obvious reasons already stated. There's far more difference based on the precise position of mercury than the position of the bowling ball and feather, especially when they are nearly touching...You know and understand this.

There's no such thing as acceleration of just the ball. Everything is relative; there are no fixed bodies. We just ignore the movement of the earth in these things, because as far as approximations go, it makes no practical difference.
They would not cross an imaginary line at the same time, since if the earth is modelled as a perfect sphere, it will be pulled slightly toward the bowling ball (the actual vector being somewhere between them because the feather has a small moment). If there's a 1 degree difference in the drop between the feather and ball, which looks about right for this experiment, this will result in a 1.7% advantage for the bowling ball hitting the earth first from the very slight movement of the earth.
