Impertinence!
For the umpteenth time, Ro resisted the urge to throw something at him; the fact that she had an object in her possession that would prove to be quite satisfying to throw didn't help. She did, however, glower at him over the orb. "You asked what makes them revolve around each other, did you not?" she ground out. Before waiting for an answer, Ro returned to her explanation. "So." She released the glass orb and it fell to the ground before hovering just inches below the floor. "Anything that has mass has gravity, objects with more mass have more gravity and thus gravitational pull. So."
In a feat of improvisation, she tossed him the smaller orb and reached up to grab her pearl earring, praying to Merlin she wouldn't lose her mother's earring in pursuit of educating the foppish upper class. "My earring. You're not physically pulled to it because it's so small. But compare that to Earth's mass? Gravity prevents us from floating upwards." She shot him a warning look to not interrupt before placing her earring on the table and motioning for him to toss her back the smaller orb.
"Gravitational pull is what we want to focus on. That's what makes everything revolve around each other. Because these large masses —" Ro tossed the second smaller orb up in the air and made them spin in the air around each other. "— attract each other. Are pulled toward one another."
