Please help me justify putting this much time and effort into a video by clicking "LIKE" and SHARING this as much as possible. Click the following: Tweet: Facebook: Please share with any science blogs or outlets you think would enjoy it.
Videos like this don't just happen. They require lots of time, and lots of favors from very smart and kind people willing to help me and you learn. PLEASE take a moment and read the following information and support those who supported me.
This is the camera we used for the ultra-high speed shots. It has the "FAST" option.
You absolutely have to check out the stuff Cal Makes. We're just goofing off in this video, but the guy is some type of glass wizard genius. It would make me happy if you bought something from him and he felt like the audience appreciated all the time he donated to this video. He basically gave me 2 entire nights of his entire shop.
I feel like we're friends at this point, and he is open to the idea of doing more videos in the future and teach me more about what he knows about glass. Let's make it worth his time.
I'm a HUGE FAN of the song Gordon wrote for this video. His landlord would really appreciated if you downloaded it so he could make rent this month.
It looks like he's assembling a new album that I may like more than Mammals:
Show him some love.
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 (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. 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.

    Prince Rupert of the Rhine lived most of his life in England. He was the son of The Elector Palatine of the Rhine and a sister of Charles I of England. As a young man he was exiled from his patrimony after his father made a failed attempt to become King of Bohemia, and became a 'Protestant Martyr' in the process. As a nephew of Charles I, he settled in England and served as a leading Royalist general in the English Civil War, he was especially noted as a cavalry leader. He later served as an admiral under his cousin Charles II. Like Charles II, he was very interested in science.

    Is it because of the shock vibration wave from the tail travels to the head? 🤔 What if you cut the tail with a method that have less vibration/shock 🤔 like cutting jelly.. Just curious.. I can't think of anything that can cut glass like cutting a jelly though 🤣

    Destin, In your video using bullets on a PRD, did you notice that the shattering happens at both ends before progressing to the centre? Also, how can you express the limit that applies to the strength of the drop, relative to the force of the bullet? What if Prince Rupert had been able to watch Smarter Every Day? Also, if a blown glass bubble is rapidly dipped in cold water, it creates a crackle pattern, which when reheated can be blown up further to create a crackled effect.. So, what determines the size of the crackle?

    Check out the Hydraulic Press Channel, or maybe their 2nd channel Beyond the Press. They used a ring of high speed cameras to get some insane video of breaking these things by shooting at the tail with a pellet gun. They also tested the hardness with their big hydraulic press and actually deformed the steel from the force. They are incredible structures.

    So what if you took the same Prince Rupert's drop and Heated and cooled it like a hundred or two hundred times. Maybe try cooling it in liquid nitrogen a few cycles. Could you make a diamond? You are only looking at a one cycle drop. Can we do it five times and make cubes or spheres? What if you took 10kg of drops and made a lens(s) from it? Would it be bullet proof? If you got a scratch on a Rupert's lens it would explode...

  50. Lorenzo Belelli

    Lorenzo BelelliOy oldin

    When you remelt the glass the tension built inside the drop is released, so by cooling it again you would get a normal prince rupert drop again. Given it doesn't explode while you're melting it.

  51. Bob Zwicker

    Bob Zwicker2 oy oldin

    I have my own question which may be related: I have often taken a piece of bent solid (not stranded) steel utility wire such as picture hanging wire. AWG20 size for example. I want to straighten this wire. If I squeeze the bends to flatten them in a vise, they spring back (at least partially.) But if I strike the bend to flatten it with a hammer against an anvil, it flattens out really well and stays flat. This is a relatively safe experiment that anyone can confirm! Why is this? (I have an idea as to the answer; related to hysteresis and sound recording on magnetic tape.) I think a good explanation would be interesting.

    Glass is amazing. When I was 9 years old, my parents took us to the Corning Museum of Glass in Elmia, New York. I was DONE. I've been utterly fascinated by glass and by extension material science ever since. So, obviously, I have degrees in Linguistics and culture. (Shrug) I'm weird.

    Question: A Prince Rupert drop is formed by pouring molten glass into water. The basic physics of a difference in expansion due to a temperature gradient being present is nicely explained here. Would you achieve a stronger Prince Rupert drop if you would increase that temperature gradient aka pour the molten glass into liquid nitrogen?

    I know this was from several years back, but if you check these here's a thought experiment. I was thinking about this awhile back. They use hollow glass spheres with 5/8" thick glass on deep sea UAV stuff. The idea of a quick quenching the outside compressing inward while the glass on the inside slowly pulls into tension. How would that work with a glass bubble 5/8" inch thick, 1/4" thick, or 1/8" with a 1-2" diameter of a spherical preheated aluminum mold maybe and the glass could be instantly cooled somehow, dropped in water or what have you. How strong? I saw your vid of you shooting Prince Rupert Drops. How tough can glass be???
