Welcome to Grand Illusions Pendulums!

Pendulums have mesmerized mankind for centuries.

Their powerful force was first discovered by ancient Chinese Dynasties in 200 B.C. and was used to predict earthquakes by detecting the smallest tremors. Galileo and Sir Isaac Newton studied their properties to keep time, explain the rotation of the earth and understand gravity.

What is a Pendulum and how does it work?
A Pendulum has a weight, called a bob, which is suspended from a fixed pivot point so that it can swing freely. Pendulums swing in an arc determined by the distance from the point of suspension and by the amount of momentum and the force of gravity. Start the pendulum with an initial light push and watch the pendulum swing slowly back and forth into beautiful elliptical loops and whirls. Different start angles provide different patterns. The patterns go from big to smaller then get bigger again as the arc of the pendulum changes. Place it on a table or desk, and witness the beauty and grace of gravity and momentum at work.
