Martini Glass Shaped Charge: Making Glass Punch Through Steel

[@OrdnanceLab]

We finally made this one. Took us a while to get it done as well..........we had a bit of a setback. Many setbacks really. We have been at it with this channel for some time and it has been literally one thing after another. Sooner or later, we will finally hit our stride and YT won't smack us down like they usually do.

The copper or glass is entirely necessary because it's the jet of molten* metal or glass that actually does the penetrating. *I'm not exactly sure what the state of matter of the glass/copper is, as I understand it's debated whether it actually is molten or still some sort of weird compressed solid.

Can you do a shape charge against a sledgehammer head Longway, and various rocks? Also, would there be a difference between glass and copper liners? I imagine you could make a 3D printed or wooden form to shape copper sheet which could be cheaper if you consider time.

[@Tunkkis]

Copper is denser and more ductile, and thus has more momentum and supposedly creates a more cohesive jet. I've seen people make the cones by electroplating copper onto approximately shaped forms.

[@ncrshane1919]

I was wondering the same thing, given the amount of work to prep a martini glass, it would probably be easier to just stamp/hammer out a copper cone from some sheets. All you need are some forms which a lathe could make, and a hydraulic press from harbor freight.

[@karolstruck9822]

Back in the day I did play with some glass. If you take a triangle file and Edge all the way around the stem you should be able to have a pretty good break. You can also try this using heat to try to get it to crack smoothly and cold. AKA so other than just using Brute Force which you can use after scoring this around you can do this by heating it up in that area and then dipping it in cold water you won't have to get crazy with it. A string with some kerosene would be sufficient. Keep up the good work.

[@_Doguru]

I love the attention to detail in these videos and the fact I still have no idea how glass can penetrate steel plates..

[@erict3728]

Turn the glass into a molten slug. Fire it at high speeds(faster than a gunshot) while focusing it all to contact the intended surface at a "pinpoint" location... Best way to visualize it. If that doesn't work, visualize a meteor strike

[@kevingooley9628]

I would surmise that most of the damage is being done by the shaped charge itself, and not the glass. At the steep angle they're getting with that wine glass, I don't think they're forming much of a penetrator, but rather atomizing the glass. A shaped charge will penetrate steel without any type of liner.

[@jacobkudrowich]

I'm too lazy to look at all the comments, so apologies if someone else suggested this first, but why not leave the stems (and even the base) on the wine glasses, and just pour the liquid explosive around them?

By the way, glad to see you all back making videos. Hope things go better for you from now on!

[@omniwing]

Ordnance lab, I have been a fan of you guys since your very first video and I watch every single one. You guys are great! Thank you for yet another very entertaining video. One thing I'd like to see is, how well does a bunch of water help to direct the blast? Like when you were blasting trees, it didn't work very well because a lot of the energy was going away from the tree. But what if you had like, a garbage bag full of water all around it?

[@Ghostmaxi1337]

Was breaking off the stem really neccesary? In ww2 the 7,5 cm Gr. 38 Hl series had a hollow aluminium tube going down the middle for the flame of the imoact fuze to go at the bottom of the round, so is the stem really a problem?

[@alden1132]

A good way of “cutting” glass is to use a nichrome wire wrapped around the glass object (in this case the stem, thought you could use the same technique to decrease the diameter of the glasses at the lip, too), and run a current through it until the wire glows white hot. It heats the glass in a very localized way, without heating the entire object. You then just dip the heated glass in cold water, and it will fracture at the point where the wire was wrapped. Obviously, you don’t want to dip a live wire in the water, so either remove the wire quickly after heating, or disconnect the power from the wires. There are videos that can demonstrate how to use this method properly, though it will probably still require some trial and error on your part.

[@alden1132]

Here is a KZbin video showing the process. There are others, as well: kzbin.info/www/bejne/jmKsf36Np7SfhZo

[@mfree80286]

I was about to pipe in about the hot wire method, but was also going to add that torch smoothing could go a lot smoother preheating the glass in a regular oven, and then popping it back in the oven and turning it off to cool extremely slowly.

[@cosmicdebris2223]

9:01 "not as well as we had hoped". I have a suspicion that the shape of that squared tube was also to blame. When it penetrated the first layer that particular shape likely had a "dampening" effect since the "first" metal plate also caved in (which can be seen) i.e. didn't offer 100% resistance to the charge. This may have damped i.e. slowed down the forced and removed a little force owing to the distortion of the metal bending down. The velocity will have been reduced very slightly but possibly enough to thwart the force or power needed to penetrate the next layer a few cm below. Can this be? 9:04 the distortion providing the dampening effect can be clearly seen.

@@jlambuth The Brits mass produced a sticky bomb that was composed of a spherical rubber bag with a metal handle, the bag was filled with gelignite and coated with extremely strong contact adhesive. My understanding is that it functioned effectively as a HESH charge, causing spalling from the inner surface of a tank's armour. Supposedly the original intent was that soldiers would throw it at the tank, where the glue would stick it in place until the fuse burned down. However the glue often failed to stick if the target was dirty (as tanks often are) so braver troops resorted to running up to the tank and slapping the charge down onto its flat upper surface, before making a hasty retreat to avoid the explosion. It was a risky weapon in many ways, as the glue could also stick the bomb to your clothing...

[@mfree80286]

I've got an idea that'll tickle your technical side... an expanding rod warhead. The trick would be in both material selection and a liner that would cushion the shockwave enough to not tear the expander apart immediately. Imagine what it would look like with a field of test dummies and targets sliced in two with a supersonic expanding hoop made from steel cable. Also curious about the effect of using a cast polymer with a heavy metal content as a liner, formed in a proper cone shape (i.e. inside a stacked funnel, or martini glass parts). Epoxy loaded to it's physical limit with copper powder, for example. I actually think there are 3D printed polymer/metal matrix parts available now through online services that are intended to be hot sintered or just used as is...

[@kbilsky]

Did you guys think about making the insert/penetrator out of very unstandard and unusual materials? For example - lead, powders (sand, iron oxide, powdered iron, starch etc), maybe even some liquids, silicone for moulds, cement... All of this materials can be easily formed to the cone shape, by casting them in 3D-printed moulds, or containing them in 3D-printed sone-shaped cases. Results can be very intresting I think :)

When you cool the glasses down, bury them in vermiculite and they will cool more evenly. There will be fewer breaks then. You can get vermiculite at a nursery as soil for cacti. You comld also try tying a string soaked in lighter fluid around where you want to cut the stem. Light the string on fire and let it burn for a few seconds and dip the stem into cold water. It should crack in a ring where the string was. My grandfather used to cut bottles in half that way. Cutting a groove around the stem with a diamond grit file could also do the job of giving the glass a weak point to break. You can shape the bottom of the glass with diamond grit files as well. I have used diamond files to fix chips in the rim of drinking glasses, so I know you can file glass without it breaking.

The explosion is essentially a chain reaction that escalates in size and detention velocity. You go from detcord to det cap to main explosives. But does it have to be a single main charge?

Here is an idea and a question or two Idea: plastic funnel with single layer of BB glued to it to form penetration material (because copper is expensive). Question, does the shape of the tapered focus device matter? Will a 3 or 4 sided pyramid work? If so welding up steel plate or aluminum plate might make some interesting tests. You could change the angles from really shallow to really deep to see if this changes how it will focus. You could also see how the thickness of the metal affects the results. This could also let you make long "knife edge" blast patterns for things like clearing trees or splitting rocks.

Shaped charges will cut steel without any liner. The addition of a copper liner to a shaped charge warhead will add superheated copper ions to the explosive jet and cut through the steel better. To the beat of my research, at the steep (greater than 45 degrees) angle the wine glass creates, there is no EFP creates, so I think he's just vaporizing the glass and leaving reside behind.
