The first time I saw it done was on Mythbusters way back in 2003. From the first time I saw that I instantly wanted to see it done with a Laserdisc. So far nobody has ever attempted it. I'd really like to see it happen. A laserdisc is much thicker and stronger than a CD. Do you think it is even possible to spin a Laserdisc fast enough to shatter it? If you were able to spin it fast enough to shatter what kind of force do you think the shards would have? In the above video it took around 23,000 RPM to shatter a CD. How many RPMs would it take to shatter a Laserdisc? When they did it on Mythbusters I believe they were also testing if the shards would have enough force to injure or possibly kill somebody. I don't think the Laserdisc would shatter at any speed but rather break apart in big pieces, if that is the case the pieces would definitely be lethal.
I really want to see someone try this, I am very curious if it is even possible. I want to say that you wouldn't be able to spin it fast enough to shatter, but even a Laserdisc has to have a limit. What are your thoughts on it?
