Why are we focused in water balloons when condoms exist? Are they too resilient?
Piss into a condom then squeeze it down into the tip until you have a happy medium between bursting pressure and throwability.
Tie it off like a water balloon, then tie an additional knot (or double knot) a few millimeters higher. Repeat process until you have a bandolier of piss-filled condom balloons.
You can separate them ahead of time or keep it intact depending on situation. Either way, I recommend a styrofoam cooler or other easily disposable hard-walled transport vessel.
This method allows you to customize the caliber of ammunition as well as providing a simple method for multiple contributors.

- Comment on YSK: A real American Civil war will NOT be like Battlefield or COD. 1 week ago:
You can’t start a strike if you don’t have a union and your co-workers don’t agree
This is a major point that those outside of the US seem to miss, I think. The sheer depth of contempt for unions and unionization I’ve experienced is a massive barrier to organizing any significant resistance. I’m very certain a majority of US citizens are unaware of what a general strike even looks like. Corporate propaganda has very successfully vilified and diminished unions for a long time.

Depends on how much effort went into reverse engineering the part, but most likely when tolerancing enters the conversation. Most machine shops aren’t able to hit those tolerances and would laugh you out of the shop.
A shop that can hit those tolerances will kick you out of the shop; there’s a good chance they already work in aerospace. They have a deeply vested interest in avoiding the accompanying FAA inquiry should it be installed or, Satan forbid, actually flown.
A non-aerospace shop capable of meeting those tolerances would start laughing at the desired price point. Purchasing a suitable blank alone would cost over $1500, much less cover the actual machining.

Aerospace manufacturing is fucking wild and is a rabbit hole worth diving into if you’re looking for some of the finest engineering porn humankind has to offer.

If an aerospace engineer made one of these he would no longer be an aerospace engineer.
Everything else you said is correct.
- Comment on genius 3 weeks ago:
Aerospace manufacturing has a paper trail longer than you can imagine. The company selling this part can tell you (well, the FAA) the exact ingot out of the foundry and every single process and every person who has touched it since then.
No machine shop will take this job; the moment this guy is unable to produce a serial number and paperwork from the real manufacturer (likely during preflight if not installation) the FAA will track down the owner of said shop. At best that owner will lose their business and pay a massive fine, at worst spend a good long time in prison.
The FAA doesn’t fuck around and for that I am thankful.

- Comment on Made in space? Start-up brings factory in orbit one step closer to reality 4 weeks ago:
Not stupid at all, that’s an excellent question! I’m not privy to the details of this furnace satellite but I have an idea or two on how I’d approach the problem. Pure (somewhat educated) speculation ahead.
Firstly, you mentioned nonconductive materials. Insulating material isn’t perfectly nonconductive but can get pretty close. I’d imagine combining insulation with the vacuum of space would limit conductive heat transfer between furnace and the other equipment.
Insulating and limiting the conductive transfer of heat doesn’t eliminate it though. You’d still need an active form of transfer to shed the heat. I’d investigate the feasibility of a convective heat exchanger; use coolant to transfer heat from the furnace to a radiator.
From there I’d study how the James Webb Space Telescope maintains equilibrium. It uses a reflective shade to shield the radiator from the sun but I lack specific knowledge of the design. The temperature difference between hot side and cold side is a driving factor in heat transfer; maximizing the difference between the two leads to more efficient, effective control.
Honestly though, its been a few years since my senior heat transfer course. Radiative heat transfer in the vacuum of space is Master’s if not PhD level specialization. I’m not at that level yet, so please take this answer with a large block of pink Himalayan salt.

Harry Potter was such a crucial part of my child and teen years. I cried when Dumbledore died. I read several of the books over a dozen times, and did an annual reread of the whole series for awhile.

Hah! My adoration of partial differential equations is far purer than even physicists could hope to achieve.
- Comment on Made in space? Start-up brings factory in orbit one step closer to reality 4 weeks ago:
There are three modes of heat transfer; conduction, convection, and radiation.
Conduction happens when two bodies at different temperatures come into contact with each other. The total heat transfer depends primarily on the difference in temperature, contact surface area and time spent in contact.
Convection takes place when a fluid (I.e. a gas such as air or a liquid such as water) comes into contact with another body. Here, again, heat transfer depends on difference in temperature, contact (“wetted”) surface area and time in contact which is primarily dictated by how fast the fluid is moving over the body.
On Earth we generally leverage these two modes. An example of mixing the two modes is a CPU heatsink and fan setup. The heatsink conducts heat away from the CPU and is (usually) distributed throughout several extended surfaces I.e. fins. The fins increase the surface area in contact with air, enhancing the rate of heat transfer.
Now, we can’t really take advantage of those in space. The lack of an independent physical medium means the heat ultimately has no where to go; this is known as a “closed system”. So if we generate or store enough heat in a body subject to the void of space without promoting radiative heat transfer, that heat will more or less stay put.
Radiative heat transfer is fucked up. Everything above absolute zero radiates heat. You mostly can’t see this exact for one glaringly obvious example; the Sun. Sol is so fucking hot that it heats the Earth through the vacuum of space purely via anger aka photons. And thanks to the miracle of science, you radiate anger right back at it.
Explaining radiative heat transfer further is outside the scope of this reply and will be left as an exercise to the reader.
I hope I explained this well enough for you or other readers to impart a ‘basic’ idea of a complex engineering discipline that I adore. I’m absolutely willing to answer any questions.

At this point I’d nearly appreciate the removal of old.reddit or RES. My desktop browsing experience hasn’t changed in roughly a decade and a half and that’s a shitload of inertia. A few trims of my subscribed list has limited my exposure to the worst of the slop and botting.
Mobile is absolutely a different situation for both Reddit and Lemmy alike. I found Jerboa shortly after the API disaster and have stuck with it since, but I probably need to look into tweaks for desktop/browser Lemmy. RES and old.reddit are a killer combo but fuck their ‘official’ app and the ‘new’ interface.
Regardless, I no longer participate on Reddit and highly prefer interacting here; more interesting and informative conversations by far.

Keyboard and mouse input for the phone is a gamechanger for me. Having a manipulatable window that I can drag and drop files to is super nice as well.
Also since Slay the Spire doesn’t have cross-saving and all my progress is on my phone I can play it without staring at my phone.
