Many of us on platforms like this are introverts, or autistic, or have social anxiety, or for whatever reason, have trouble meeting new people or engaging with strangers. If someone wanted to engage you in conversation, what topic would you be happiest to talk about?
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.
