This is how I spent my Friday evening alongside calculating how close you could get to the center of a black hole without dying or getting sucked in

What makes that interesting is smaller black holes produce gamma radiation so you have to balance shrinking the point of no return with radiation poisoning

By my estimate a black hole with a mass in kilograms between 1E14 and 1E15 (mid sized asteroid) are the sweet spot where you could get within 50ish meters if you don't mind a tiny bit of cancer
