It seems that depending on the type of glass and the direction of the waves (longitudinal, shear, or Extensional) the speed of sound in glass can be between 2300-6000 m/s

Longitudinal is the type we normally think of though, and that is between 3900-5600 m/s. Which is still much more variation than I was expecting.

The speed of sound in air is around 340 m/s depending on temperature.

So if the op is correct about the speed, then it seems the cracks propagate slower than the speed of sound in glass.

Do you have more specific product examples?

You’re doing the gods’ work

I think there’s a lot of great ideas in here, but I’d start with the stuff that, when you need it, you need it now.

Something I didn’t see mentioned yet was a wrench to turn your water off at the line that goes into your house. If you’re on a well, then whatever tools you’d need to turn that valve off. If you spring a bad leak you want to shut that off asap

A few other things that seem like good things to have BEFORE you need them

• Plunger and drain snake (Good to have both, sometime the plunger won’t cut it, but it’s much easier to use a plunger if that’s all you need)
• First aid kit
• Fire extinguisher
• Carbon monoxide/smoke detectors
• Spare keys, give them to people you trust or hide them really well so you don’t have to break in if you get locked out
• A big bucket for leaks, mopping, etc
• ladder
• Generator if you can afford it
• Emergency bag with food, water, flashlight, spare batteries, cheap phone, list of numbers, map, first aid kit, etc

Those are the kinds of things I’d look to buying first since anything else you can just go get when you need it.

Small pet peeve of mine, wd40 is NOT a lubricating oil, it’s a penetrating oil, and a cheap one at that.

Penetrating oil is what you use when things are stuck. It will dissolve whatever old oil or grease was in a joint, and flush it away, and it can be useful for rust removal as well, but it is NOT protective. Get some kind of protective oil like silicone, lithium grease, or balistol for lubrication and protection.

Right? It’s weird. It’s ALMOST like they actually don’t care at all about the poors and really just want to make their billionaire buddies happy.

Thank goodness THAT isn’t the case.

It would be even worse if the only alternative was purely performative when it came to class issues and only better because they’re contrasted against literal fascists. That would be a truly sorry state of affairs for the BEST COUNTRY ON EARTH. Good thing it’s just a money problem.

Why the * in Romans? Is Roman a bad word now?
