Officially, this bench exists to stress-test office supplies under unusual gravitational conditions. Unofficially, it is a physics toy. Drop paperwork, flip gravity, feed the black hole — Facilities will sign off on all of it.
Nothing on this bench can break. The black hole only eats toys, the big bounce just tosses everything around (no noise, no damage), and Clear bench resets the whole lab whenever you want a fresh start.
