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.
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.
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.
This is, if on the shoulder, probably the deltoid.

Because the left side is considered evil for some reason.
sit on your head
ball spinning on its axis- rotation ball spinning around the head- revolution/ orbiting
They are drums that you balance on your head whilst spinning:)

Don't sit up.
Just one head = 2/4 = 1/2
Its where your head comes off. so i think u shouldnt use software cuz it will blow ur hed off
Well, can't tell you off the top of my head, but if you cruise into a lab and throw 500 ul of 2M CaCla2 into a centrifuge tube, put it on a scale and you will have your answer. I mean really? The point of lab is to do it!
A trimmer With a clutch allows the head to stop spinning when you let off the gas, and a NON clutch keeps spinning,
there is no such thing as the black head. But there is a black hand
