What would you think when someone is ripping a CD just by
spinning it crazily fast. An immediate thought that strikes our mind is, why
would someone do that?
Here, two guys named Gav and Dan, they have done something
really interesting which, at the end makes you to think " Why shouldn’t I try
that? That’s really cool! ".
Slow motion photo (video)graphy is an engineering marvel which
captures moving objects at unimaginable precision. They are simply called as
High Speed cameras. Yes, if you have an iPhone 5S you can capture Slo-mo
videos. Well, you may need to think twice whether it had any significant use to
combine madness and science, like these guys do.
From previous experience, it is known that a CD can
withstand upto 23000rpm. When it goes beyond that, it just rips apart. Combine
this with a high speed camera which can record videos at jaw dropping 1,70,000
frames per second, you just see the unimaginable. The video shows the CD shattering into pieces
which you can never see in realtime.
Now, the science behind it. From high school physics, we
know the terms such as Centrifugal force and centripetal force.
Centrifugal force is the force which tries to push the
objects away from the spinning axis along the spinning direction and the
centripetal force does the vice versa. At such high speeds, Centrifugal force “overtakes”
and that’s what causes the ripping.
The guys in the video say, a video which was recorded only
for 4 secs in realtime plays for about 7+ hours. Now you can imagine how “slow”
it is.
Watch the video and enjoy!
Thanks!!!
