Your question is vague. You're not dropping something off a cliff it's moving and 400km up and 25,000km/h.
Any object coming from the ISS will be going 25,000 km/h. I don't think "aim" is the word since the Earth is moving rapidly beneath the object. There's no stationary point to aim at. Plus once the object of whatever shape in the atmosphere drag which causing friction to burn it up is not controllable. It would break apart and each object with different mass now has its own path and velocity.
I'm amazed any of it works as well as if does now.
