All about the Herzstein Foucault Pendulum at the Houston Museum of Natural Science

First exhibited in 1851 at the World’s Fair in Paris, the Foucault Pendulum (named after Jean Bernard Leon Foucault, the French physicist who invented it) is a visual demonstration of the Earth’s rotation.
Throughout the day, the direction of the pendulum’s swing appears to change. Actually the Earth is turning under the pendulum as it swings. At Houston’s latitude (30° N.) the pendulum will precess through 180° or halfway around each day. During this time, it will knock down all of the pins.

Even you admit it needed a push to get it going.
If the earth was rotating at 1000mph on its axis and rotating around the sun at 667000 mph would that be sufficient to get it going? The answer is...no, because the earth is motionless.
This is a novelty.

Another moron demonstration of natural born stupidity.

They are not claiming the pendulum is in motion because the Earth is. The floor and building is shifting around the pendulum which is kept in motion by a magnet (like the toys) and has a near 0 friction swivel at it's attachment. Perpetual motion doesn't exist...
"Swinging from a cable over 60 feet long, the pendulum's period is just over 7 seconds. The pendulum receives the energy needed to keep swinging from a magnet surrounding the cable at its top. As the pendulum reaches the middle of its swing, it closes a circuit that activates the electromagnet."

" the earth was rotating at 1000mph"....Nothing "rotates" in mph. mph are the units of linear velocity and angular velocity and tangential linear velocity are not the same thing. The correct speed of rotation of the Earth is 0.000073 radians per second. Take care.

"Even you admit it needed a push to get it going."
LMAO!!!
How to say you haven't got a clue!!!
Now explain how the precession varies as a function of the latitude.
