Gr************:
2:12 epic moment when the birds started flying
Kn****************:
0:26 "Fart."
Ma*****:
0:37 Those people must be thinking "What is this man on the roof of my college doing dangling a slinky in my face?"
wi********:
00:00 and I have work tomorrow. But im watching Derick. At least these videos are transferrable in engineering. Just
Vi*********:

BY****:
0:28 fart.
Wa*********:
soo epic with the deafs flying away on the right at 2:10

We*****:
Let's say we have 1 km slinky, we drop it, will the bottom stay hanging in air without dropping to earth?
Od**********:
THE OLD MAN HAS JEDI POWERS!!!! :D
But i did see an old man "drop a big slinky"
si*************:
That crocodile dundee reference though.
So***********:
I'm curious: how long did it take for this slinky to return to its normal shape?
Pr*********:
What if u dropped this supersized slinky in long transparent tube not much wider than the slinky, so top of it cant overtake parts that it hit? :D anybody interessted in that?
My*********:
I new the Earth was flat and this proves it!
Jo**:
WAIT! what would happen if u were at the top of a building and had an insanely long slinky hanging down, and a person hanging onto the end of it then dropped it? Would the person stay stationary until the rest of the slinky reached them or would the added wait push the slinky to the ground before the top of the slinky reached them????????? Someone please answer this question is eating away at me!
Ai*****:
Kto z kgof?
Pa********:
Combine this with a bunch of springs, levers, switches, magnets, a few buckets of water, an hour glass, so aluminum foil, and you got yourself a perpetual motion machine. I just know it.
De****:
IT LEVITATE
Ro********:
Amazing. How did it stay there?
Fe************:
with enough mass acting on the slinky, could in some point the bottom of the same fall at the same acceleration rate of free fall objects? I mean, could gravity overpass the spring tension?
Pa********:
So if I were to have an unending slinky, and I leave the top, the bottom floats?
Th********:
I love this experiment! The first time I heard about it I thought I had it figured out and the first time I tried it I thought had had verified my thought. But this super sized slinky really tells me what I thought was going on IS what is going on.
The slinky is a spring right? So all stretched out it just wants to collapse on itself right? So being a spring with relatively equal tension on both ends wants to return to a center point.
SO, as the top half of the slinky is being pulled down by both Tension AND Gravity, the bottom half is being HELD UP by Tension and the MIDDLE is falling with gravity.
So what is going on is the top half is falling twice as fast, the middle is falling at regular speed and the bottom is being pulled UP at the same speed that the Middle is falling so that it appears to not move.
So @Wendy Wirawan , waddia think?
Ma******:
Although they didn't provide any explicit explanation of what really happened, taking out gravity as a variable (pushing the spring sideways) implied that this experiment cannot be done with a vertically inelastic or compact object such as an elongated stick/rod. The spring is simply the key variable. I stil find it amazing how the bottom slinky did not just seem to stay intact in that specific point in space but actually resisted the force briefly before giving in. It really looked like the bottom end of the slinky wanted to stay there as the spring pulled it up for the last time before deciding to completely submit to gravity.
