Any tool escaping manipulator's hands will not necessarily follow Earth's
gravitational field, but will land in the most unreachable location in
the prototype, smashing on its way the most expensive component of the
prototype.
This will know only one exception if the tool is particularly heavy, in
which case it will land on the manipulator's foot.
-- Vuilleumier's Third Law (also known as Selective Gravitational Field)
