Haha, In the end they start dancing and beeping around the hammer =D

no it's the moonwalk xDD

#1 its hammertime

OMFG so that's why they went to the moon!

I could have saved them a lot of money.

#6 As far as I know, they were able to create a vacuum in the 1970s, so I bet it was proven long before people went to the Moon... Testing it out there was just double-checking

The first moon landing was on July 20, 1969, before your 1970's vacuum theory. Tho I'm sure that they could make a vacuum way before the 1970's, since all you're doing is sucking the air out of a container. And they probably tested components of rockets in vacuums before sending them out.

and our vacuums dont have gravity?

richardhalo, heavier objects do not fall faster. it is based on air friction that makes the feather fall slower on earth because the atoms and molecules in air hit against the object as it falls hence the lighter the object is, the more impact these particles will have on decelerating the object from the acceleration of gravity.

Gravity on earth pulls at about 9.8 metres per second per second. notice that does not say per kg.

We did this test during science class way back. A vacuum pipe with a feather a small lead ball and a piece of paper. And they went at equal speeds through the pipe.

#1 They are not dancing, its just the way they move since there's no gravity.

#11, usually I am careful with moderators, but this time: Vacuums have no gravity themselves though they often lie in gravity fields. Vacuums in general have no push power, that is why weak glass surrounding them often implodes and plastic with nothing is flat.

they done this on mythbusters by putting them in a huge vacuum and yes this is real becouse of the air resitance ore somthing is the same so there is the same ammount of drag on them both pretty cool tbh

Wow, I'm impressed, I was expecting a totally different argument in here!!!

... lol ... pretty much every second commentator states something silly and fail

You better not drop it on your toes there.
Closest hospital is 384,403 kilometres (238,857 mi) away.

"dancing and beeping around the hammer" - real world first person lol i like the: "a falcon feather...from a falcon" they say part of the entry shielding is made from dove feathers, so you can see where hes coming from... makes me think, why do they say "re-entry" since getting into space is more of an exit routine?

#16 your comment just fails. yes what you say is correct but you seem to suffer in comprehending what i was saying.

Apollo 15 (July 26–August 7, 1971)

from 0:43 till the end R2D2 was also talking something or celebrate

My only comment about this whole thing has nothing to do with the video which is really a shame. It has to do with the ensuing discussions. My comment is on the failure of our education systems to teach our children (past and present) the basics, AND the failure of parents to ensure their children receive a proper education. Sadly I can't place all the blame on parents or the education system. Currently there are way too many of us are happier in our own ignorance than in the ability to understand that WE actually are not the center of the universe.

Most of these discussions should never have happened unless the misunderstanding people in question are under the age of 14.

Now that's enough on that, let's go to the school sponsored sports program of your choice... Get rid of Recess in schools, but for goodness sake let's keep sports a school function!

Now that is pretty silly, the feather had no protection from the solar radiation and 250C heat whatsoever, it should have burned up to a crisp in less than a second if that was really the moon!
