Possibly, but it is suspiciously similar to an exhibit at the Oregon Museum of Science and Industry (OMSI) where a cable is suspended three stories up and attached to a steel ball that swings like a pendulum. The rotation of the earth causes it to move ever so slightly around a circle as it swings. The thing will eventually knock all the pins down in a 24 hour period. Just wondering 'cause it seems so random...
Did they move the pendulum downtown to the new location on the Willamette River?
Indeed!
Look up Foucault pendulum in Google® and look at the pictures.
There are many museums that have these things set up.
There only TWO places on Earth that would have one rotation in 24 hours: the north or south pole.
Any other latitude would have less and less rotation until a pendulum is set on the equator; where it would have none at all.
