👉 Alright, let's break this down in a way that's as entertaining as it is enlightening! Imagine a scenario where Sister Gravity, the overly enthusiastic and slightly mischievous gravity spirit from the 'Gravity Falls' universe, decides to play a little prank on positively charged brain cells in a lab. She swoops in with her cosmic charm, saying, "Hey, scientists! I've got a gravity-grabbing idea! Let's alter these positively charged brain cells to give them a 'ister' feeling of negativity!"
Now, for an edgy example sentence: "The quantum physicist's latest brain experiment went horribly wrong when Sister Gravity altered the positively charged cells to a state of existential dread, and now we're talking 'ister' gravity waves." Just remember, in the world of science fiction, a little bit of sisterly love can go a long way, but don't let it get too much fun!
