I have this story where this dude turns himself into a mutant by saturating himself(drinking, cooking with, bathing in, inhaling, and injecting it) in this stuff he made with energy drinks, protein powders, vitamins, veggies, and more(and irradiating himself as well). I imagined and want it to be liquid.
But see...he has no access to a blender as he is shrunk down to around an inch in a building. There is a cockroach civ in there with him but they are hostile and are have around ww2 level tech, so no blenders yet, I think.
So how could someone make a mutant smoothie without a blender?
As this story is already not scientifically sound, please ignore the ramifications of the Square-Cube Law when answering this.
