  • An excellent question!

    Hmm, water would be a very difficult (though maybe possible) material to build with. If you used those long balloons, like for balloon animals, and filled those with water, that could make like a semi-rigid beam. Then it’s just a matter of using the beams to make a structure, an arm, and a pivot point. You could use unfilled balloons as additional teather and possibly to make a pouch for holding your projectile.

    To help with rigidity, after filling the water balloons, you could then spiral some duct tape around the entire length of the balloon, like wrapping grip tape around a hockey stick, that would keep the balloon from expanding unevenly or bending, it shouldn’t flop all over.

    Just to maintain the design themes, I imagine using this to fling water balloons exclusively at little sisters.









  • Well, this is a stupid idea and it’s probably not going to happen. That said, if someone were to do this, it probably wouldn’t contribute much to Kessler syndrome because you wouldn’t actually want a million free floating satellites, you’d want a million physically connected satellites. Picture satellites designed to link up into a giant grid. Effectively, that’s just adding 1 large satellite, built over a thousand launches. And you wouldn’t want it in low earth orbit either, you’d want it higher, where it could get sunlight 24/7 365. And at those middle orbits, between leo and gso, there’s really no competition for space there, that zone is empty.

    Ok, well first off, hunting spiders are a thing, so arachnids can be effective predators without webs. Let’s suppose that hunting spiders evolved first and web spinning came later (I have no actual knowledge of spider evolution, but let’s go with it).

    So what do those hunting spiders use web for? I believe they use them to make those fuzzy egg sacks or nests, so protective structures in general. I could totally see that evolving first, the ability to make silk for building nests. Actually many different species have evolved something like that, using excretions to aid in nest building, birds, ants, fish, caterpillars, other insects, it’s actually a relatively common trait to develop. Nests are good for hiding, protection from the elements and thermal insulation, a home is nice to have!

    I could see it become beneficial if some spiders then developed sticky nests, sometimes bugs might wander in and get stuck, free meal. And then after that, some might develop larger nests, the greater the area of this sticky nest, the more effective it is. And that basically gets us to modern sliders spiders.
