• just tried dropping a weight along side the extended slinky. and the slinky looks like it falls heaps faster than the normal weight andï»¿ lands on the ground first. are my eyes being cheated?

• I don't think so. The centre of mass of both objects should hit the ground at the same time, but the top of the slinky is going so fast by the time it gets to the bottom, it often passesï»¿ the bottom and would therefore hit first.

• Hey 1veritasium, i saw u on a show in australia called The Catalyst.It was awesome seeing u there explaining theï»¿ physics of Slinky

• Yup, I'm living in Sydney and working onï»¿ some segments for Catalyst... stay tuned!

• is this a hobby or itï»¿ is your job?

• Let's say neither. A job pays andï»¿ a hobby sounds like an amateur pastime. Veritasium is a passion.

• Theï»¿ top end comes down just tried it

• the host is so awkward.ï»¿ its annoying. nonetheless, yey physics

• I just attended a student academic conference for Korean high school students and this video was used in one of theï»¿ presentations. A student did his physics project on this very question.

• Forgive me if I'm mistaken here. But I believe that the answer to planetniffer's confusion isï»¿ because he is likely holding the static object at the same height as the top of the slinky, which is not the same height as the center of mass of the slinky. You would need to hold the static object at about the middle of the slinky to achieve the desired "same landing time" effect.

• I'm sure I tried this with my Slinky (Back in the 'day'!) and I'm sure the endsï»¿ come back together and then just wobbles before hitting the deck.

• god i would likeï»¿ to report a bug

• Derek! We just watched this video in Physics! Iï»¿ was so excited!
