Mystery of Prince Rupert's Drop at 130,000 fps [video only]
YouTube.com ^ | 3-22-2013 | Smarter Every Day

Posted on 12/09/2013 11:32:19 PM PST by servo1969

This video involved about 2 months of research, and me reaching out to several individuals. I would like to thank everyone who took time out of their schedule to contribute to my wacky research. A big thanks to the following people:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

My wife and kids. I'm sorry this took so long and I wasn't the kind of active father I want to be during the 5 weeks it took to make this.

Dr. Martyn Poliakoff for getting me access to documents which details experiments on the Prince Rupert's Drop by the Royal Society http://rsnr.royalsocietypublishing.or... (behind a pay wall)

Being able to calculate the failure front velocity of a Prince Rupert's drop is a pretty big deal. For years this was a scientific mystery. High speed camera technology is only recently fast enough to provide data like this. Thanks to Vision Research for letting me use the V1610 to try to unravel this mystery for the public in general.

Rob Kuefner for reaching out to me and offering to convert certain equations into LaTeX format for me.

Dr. Jeff Evans from UAH. A friend and neighbor who just happens to have a PhD and be an expert in fracture mechanics. http://bit.ly/YLezDA Thank you for helping me by pointing me in the right direction in the early stages of my research. It's time we hangout again.

Brian: thanks for letting me use your green screen and telling me about Orbix in the first place. I stayed up there til about 1 or 2 am two nights in a row acting stupid in front of of the camera all alone. Now that I look back at that footage without the context of this video, it's all very strange.

Thanks to Loïc Samuel for taking time to make the custom TNT Degradation graphic!

P.S. There was some old guy walking around the track at the park when I was filming me jumping on the bridge railing. I'm pretty sure you kept walking until I was done just to make sure you wouldn't have to take me to the hospital if I broke my leg. I'll never meet you again, but I'm grateful for this kind gesture you didn't know I noticed.

Well, I had no idea what that was about from the post, but checked it out anyway. Pretty neat!

The current economy and financial system is an analogy to the Prince Rupert drop.

One false move and the entire thing blows.

I’ve been following Smarter Every Day Minute Physics and Veritasium on YouTube for a while now. I suggest everyone give Smarter Every Day a go first because they often use lots of weapons for physics experiments. The Veritasium guy is a liberal, but his science videos are excellent.

Thanks, not only is this video cool…

…but I learned a life skill by watching the same guy's video on "Poop Splash Elimination".

It is particularly amazing to watch at 1080P!

Someone posted this Prince Rupert’s Drop video on the Undead Thread a few months ago, and then my kids watched the whole “Smarter Every Day” series. Lots of fun!

Indeed. I have been lying awake at nights, wondering about that failure front velocity. Even though I have never heard of a Prince Rupert's drop until this minute, I wondered.

Now to watch the video and learn, at last, what a Prince Rupert's drop is.
