If you're an academic who would like to collaborate on a paper on this topic please reach out. I have lots of data that I didn't share in this video and I think we've made some significant contributions to the body of knowledge in this area. The main reason I wanted to perform this experiment was to better understand the radial fragmentation distribution of the Prince Rupert's Drop. After this experiment, I'm not so sure it works like I originally thought. Also, I really wanted a Prince Rupert's Drop shirt. If you'd like one, as well here's the link! www.smartereveryday.com/store Thanks again to everyone who supports Smarter Every Day on Patreon. I'm sincerely grateful! www.patreon.com/smartereveryday

could you make a rupert sphere. and how about encasing the tail in something very vibration absorbing, thus making it much tougher. Maybe a substance very particular like non newtonian liquids. Something that really soaks up vibration energy because that's what kills otherwise very strong glass.

Hey! My research group and I(at MIT) just filmed some exploding Prince Rupert's drops at 492,754fps through a polariscope. It looks really cool! All of the internal stress patterns are very visible. There is actually a stress wave that propagates through the drop far ahead of the actual explosion front. It actually creates a standing wave within the glass between the end of the bulb and the explosion front. This standing wave increases in frequency as the explosion moves closer to the bulb head until it finally shatters too. You might find it very interesting. I am currently editing footage to put on my channel, but I thought that you of all people might be very interested in this.

@rickw9799 Рік тому
Three recommendations here: - Try letting the resin fully harden, I'm curious if the shockwave is powerful enough to shatter the hardened resin. - Try ballistics gel instead of resin. This should more fully capture the 3d visualization of the drop shattering. - Try clear gelatin, as the ballistics gel may be slightly too hard to allow the glass shards to travel through it. I loved this video and am fascinated by just how FAST these things shatter!

If you want to try this again, try doing it in water and use Laponite RD (rheology modifier). 2% of laponite in water will gel the water enough to suspend a marble.

@@chadwilson7754 It's like pouring urethane. By carefully controlling the ratio between casting solution and hardener, you can arbitrarily set a final shore harness. It's how they can make skate/longboard wheels so consistent. Only difference is ballistic gel is on the softer side of the shore scale, and it's usually engineered to be as transparent as possible to allow for better viewing of bullet paths.

This is science, and if youtube videos don't show that part, children get really discouraged when things don't go their way with experiments.

@DisIntegratedLife Рік тому
That was one of the things I always loved about Mythbusters. Failure is always an option. And in science we often learn more from failure than we end up learning from success. I've even seen experiments where the eventual success was only understood because of the previous failures. Science is at least as much the journey as it is the destination.

@robertlenders8755 Рік тому
I think to best capture separate fragments of the PRD you'll want to use a "Bingham Plastic" fluid. These types of fluids are solid at low shear stresses but liquid at high shear stress. If you can find the right fluid it should hopefully be thin enough to shear during the explosion and then become solid immediately as the explosion slows.
@constantprayerwarrior Рік тому
So a reverse ooblick
@JazzyFizzleDrummers Рік тому
That sounds promising. The pressure of the resin was collapsing the drop back in on itself. That might solve the problem.
@restorer19 Рік тому
Does the reverse exist as a sort of shock-sensitive epoxy? Something that will be a slow-cure resin under normal conditions, but give it a good shockwave and it solidifies immediately and with enough recovery time/hysteresis to hold the fragments in place until the resin can fully cure?
@MendTheWorld Рік тому
Don’t know Bingham Plastic, but it sounds like the fluid you’re describing is thixotropic.
@robertlenders8755 Рік тому
@@MendTheWorld Thixotropic is a related term where the viscosity is time-dependent after a force is applied. These is some overlap with these fluid categories.

My wife was screaming at you for “doing it wrong” with regards to the epoxy. Her point being that you’re mixing it way too fast which is causing the epoxy to cure too quickly (also causing the larger exothermic reaction). There would be fewer lines in the epoxy and it should have more of the viscosity your seemed to be going for.

I have done a bit of epoxy work, and the brand I use (Totalboat) actually says to not use a mixer/drill. Probably OK for your purpose, but I did not read that warning before I laid a bar top, and had major problems with the epoxy curing right. Subsequent pours were all perfect, where we hand mixed. Another suggestion, put one of these PRDs into ballistic gel!

Loved it. Just a thought: would you get the effect that you're after if the PRD was set in ballistic gel?

I'd use agar-agar. It can be made cold and it's super clear for a gel. What's cool about that is you can cast a tool for breaking the tail in with it and encase the entire thing in ballistic gel so it can't easily draw in air like the observation that was made when they finally got it.
@mattsnyder4754 Рік тому
It’ll just blow the gel apart

@slartyb52 Рік тому
Hi. Love your videos. This one is great ... but there's a lot of room for improvement with regard to your epoxy processing. 1) Use an appropriate epoxy: The one you are using is meant for surface finishing in thin layers. Making big quantities in deep sections is a bad idea, as the exotherm will be so high, the cure will be uncontrollable, and a fire risk. 2) Mix, mix, mix! Mix until clear, then transfer to another container, and mix some more. 3) Removing bubbles with a vacuum only results in boiling of one of the epoxy components, changing the ratio slightly. Probably won't make much difference, but all those bubbles coming out of the epoxy are not trapped air bubbles. I would *LOVE* to see one of those results sawn in half, and put under a microscope!! Keep up the good work.

Use a mixing nozzle, dump first bit out from nozzle then feed from the bottom of mold. Use a epoxy with slower set time that will help with the bubbles and exothermic run away.

You sealed the end to prevent air. When you said that, I thought to myself, "If you wanted to see the air gaps between the glass fragments, why not pour colored water down the spot, before you seal it. Contrast would help you to visualize the fissures within the glass." In other words replace the air with a colored liquid. The liquid would probably have to be fairly thin with little surface tension. Something that would not react with the epoxy. Acetone, paint thinner is out of the question. Maybe colored alcohol.
@mycosys Рік тому
IPA would be a likely solvent, very low surface tension. Suggested the same thing.

Not sure if this has been suggested in the comments anywhere but have you thought about trying ballistics gel? Like the kind used in testing the transfer of energy from projectiles to a target? They make kits that people mix themselves then some hours later (not sure but think its 24-48 hours) you have a block ready to go. The gel may would allow for more fragmented expansion. Wasn't sure exactly what you were goin for but excellent job and you got some BEAUTIFUL videos to show for it. Awesome Job.
@sparrowthenerd Рік тому
In case you ever want to try this again, epoxy kicks way faster if its too deep! If you want to slow down the cure to get the perfect "sweet spot" try mixing in shallower batches in multiple cups

@curtisaitken7027 Рік тому
As someone who works with art resin…you need put part B in first then part A. Mix very well to get the sides and bottom of all the material better. That’s why it wasn’t clear and you had clouds in the final epoxy. You need to de-gas more and you need to make sure you are in a better temperature controlled environment. Read the directions of the epoxy for temperature required. I’d love to work in this…I’m going to work on this at home.

It makes no difference whether you pour A into B or B into A. What does make a difference is as you said, thorough and complete mixing.
