[TheForge] A Balancing act

[Bob]

     Set the impeller and shaft on 2 level / parallel rails (knife edges 
best but smooth round rods may work) and see if it rolls to a position 
with the same fin down.
It should stay in any orientation if it is balanced.

We must reject the idea that every time a law's broken, society
is guilty rather than the lawbreaker. It is time to restore the
American precept that each individual is accountable for his actions.
