Pendulums can be made of different materials. The best length for the pendulum is six inches. As long as the bobber - or weight on the end is not too light - nor too heavy. It should weigh less than have an ounce. The best shape for the weight - or point - is something that comes to a point.
You can make your pendulum or buy one. Pendulums are a simple way to communicate with the other side. I have seen people in stores use them to select products such as - books - produce - clothing - just about anything.
The most common types of pendulums are:
- a crystal tied with wire then suspended on a chain or cord
- a chain necklace with some kind of charm suspended at the bottom
- a chain with metal pointer at the bottom - these are usual store bought
- the human body - which is a pendulum that can move back and forth - or side to side
