The big reason is safety. Depending on the centrifuge design, you could easily break fingers or even tear them off if they got caught in the head. It's very easy to underestimate the rotational inertia of the head. Some centrifuges have safety interlocks that won't even allow you to open the head enclosure if it's still spinning. Also, if you do manage to stop the head manually it may produce enough of a jerk to re-suspend some of the precipitate, in which case you've wasted your time as you'll just have to spin it down again anyway.

What is the effect of rotation on the endolymph in utricle saccule and cochlea?
Rotation of the head causes the endolymph in the utricle and saccule to move, stimulating hair cells and sending signals to the brain about changes in head position. In the cochlea, rotation influences the movement of the endolymph within the semicircular canals, which helps to detect rotational movements of the head.
Can spinning a child from his feet cause vomiting or brain injury?
Spinning a child by their feet can cause dizziness, disorientation, and potentially vomiting due to the rapid change in movement. However, it is unlikely to cause brain injury unless the spinning is excessively forceful or if the child hits their head on something during the spinning. It is important to supervise children during such activities to ensure their safety.

Why do you feel the spins after using cocaine?
To understand why, you must understand the human vestibular system, this is a small structure in your inner ear that helps you to maintain balance. The vestibular system is composed of three semi-circular canals. The semicircular canals are interconnected tubes located inside each ear. The purpose of the canals are to tell your brain if your head is turning or rotating from rest. It is able to do this since the canals are filled with a fluid called endolymph and contains a motion sensor with little hairs (cilia) whose ends are embedded in a gelatinous structure called the cupula. As the skull twists in any direction, the endolymph is thrown into different sections of the canals, due to the resting inertia of the endolymph. The cilia detect when the endolymph rushes past, and a signal is then sent to the brain. The spinning dizzy feeling you get from spinning horizontally involves the horizontal canal, and it is aligned roughly horizontally in the head. The horizontal canal detects horizontal head movements (such as when doing a pirouette). When you being to spin, the endolymph rushes past and you are told your head is turning. However, when you spin for an extended period of time at a constant rotational velocity, the endolymph has time to equilibriate in the semicircular canal and hence no longer pushes against the cilia, causing your brain to think your head has stopped spinning. The instant you stop, the endolymph, normally travelling in a circle in the semicircular canal but because you were spinning as well, was unable to detect the spin, rushes in the opposing direction as inertia from the initially moving endolymph is forced to a stop. This triggers the cilia and causes your brain to suddenly start thinking your head is spinning in the opposing direction despite the fact it is not.
