The terms frequency and vibration are thrown around a lot in the witchcraft community, especially amongst New Age practitioners, to describe people in certain states, explain the magical properties of crystals, and suggest that by controlling these frequencies we can reach our highest self. The hosts take on this topic and attempt to explain what these terms actually are, how we empirically measure them, and address their misconceptions in magic. This is going to be a fun one, so grab a wine glass and bring it to the lab where we'll try to break it with the resonant frequency! ;)
