Meanwhile, most sex shops: selling jelly which just straight up melts with time, TPE/TPR which are porous and might melt when boiled and therefore pretty much impossible to keep clean, PVC which they promise doesn’t contain phthalates this time, and silicone that has about a 50% chance of actually being platinum cured. DIYers can’t be much worse, as far as I know, they either outright state what methods and materials they use or will provide them upon request.
I think it’s a Ukrainian RK-3 “Corsair” ATGM. You can see the RK-3K marking there, suggesting it’s a tandem-charge HEAT warhead. I’m guessing the first one malfunctioned and didn’t launch, but was probably already primed for it?
