via Journey of Curiosity ------- If you listen carefully to the tone as I sweep between 315hz - 800hz it is only when 380hz is played that the water displays a response.
Lower or higher frequencies there is nothing, until it passes through or hovers around that frequency.
Also, notice how quickly it comes into being, and then suddenly disappears as the frequency changes. Everything has a resonant frequency, and it differs on many variables, If this were a different viscosity or size for example, it may have a different resonance 🌞🎶🌈 To see more videos, subscribe to the YouTube channel! https://www.youtube.com/channel/UCychrbgnGCwlmVZcAUGsXRA
