Take a feather and a hammer to the top of a stone wall. Now, set the hammer on the wall, and hit the hammer with the feather as hard as you can without hurting the feather. Examine the hammer for damage.
Now, set the feather on the top of the wall, and hit it with the hammer as hard as you can without hurting the hammer. Check the feather for damage.
Now, scurry away before somebody comes out to holler at you for hammering on his wall. When you catch your breath, ponder upon this question: Aw, dang! I forgot what the question was.
I think you wanted to know which was heavier, a pound of feathers or a pound of hammers. The answer is that they weigh the same, but only in a vacuum. The feather may not cause much of a problem but the hammer will wreck the vacuum, especially one of those bagless types. It’s much easier to use a balance scale and put a duck on one side and a suspected witch holding a hammer on the other side. If the duck is heavier than the witch and the hammer then the duck won’t float, and you can’t hear it’s quack echo, except in a vacuum, and if you vacuum up a duck it will quack a lot.
According to my son, a pound of feathers is heavier than a pound of anything else, because not only do you have a pound of feathers, but you also have the weight of what you did to those birds to get the feathers in the first place.
Obviously faked footage. I watched the vacuum chamber test video in the other thread twice just to make sure, it definitely shows the feather hitting the ground first, and both the bowling ball and the feather fall very slowly in a vacuum for some reason. They should fall even slower on the Moon because of the weak gravity but in your video they both fall just as fast if they were on earth.
