Idea for new post on pendulums

This is a pendulum that friends got me for my birthday. The stone used as the weight is Fluorite


Something I’m working on for later….I got a pendulum as a gift and so I’ve done more research in the physics of pendulums and their many uses throughout history.  They are so simple in design but the uses for them are so complex and they’ve been so relied upon as time keepers, gravimeters and even as holistic healing tools.
