So they were talking about this on the news this morning, and while the news casters were doing their best to talk down the science, and how much money was likely 'wasted' on this demo, which makes me angry to no end for so many reasons, I wanted to post the videos because they were just so cool.
The question is, what happens when you are holding a slinky from the top so it dangles down and release the top. Does the whole thing fall at once, does it collapse then fall?
Make your prediction, then watch:
Ok, did it do what you expected? What do you think happened and why?
They do a second video with a tennis ball attached to the bottom of the slinky. How does this change the experiment from the first time? Do you think it will change the outcome?
Make your predictions, then watch:
Did the addition of the tennis ball effect the experiment like you thought it would? Is so, why? and If not, what do you think you should change about your prediction?
I love physics
