Does anyone else not just spin but play with the conservation of angular momentum by moving their arms between outstretched and towards the body to change rate of spin?

I've never tried that, usually stick with outstretched.

I don't spin much these days, though. Only a few times in the past year and a half.

I spin on my trampoline. I don't think I am coordinated enough to change the rate of spin. I have almost fallen off it many times.

It can be very difficult to change your arm orientation while spinning without falling over. The change is rotational speed is larger than you might think. Try it in a good office chair with your legs and arms. You can go from slowly spinning around to spinning so fast you get sick, just by folding your arms and legs in. :D

Yes, it's even more fun in a spinny office chair :-)

I used to spin so much the blood would all go to my hands. Then I'd stop and let it flow back to normalcy. I loved the sensation.

Indeed. Haven't had a decent one around in years. :(

I do this if I'm spinning in a office chair, I also stick my legs out and pull them back to do the same thing.
