The shape of sound demonstrated with salt.
The PLANE IS VIBRATED AT SPECIFIC FREQUENCY. The waves travel across the plane and at some places they add together and at other places they cancel out. Where they cancel out the salt sticks because there is no vibrations and at other places it just gets vibrated away.
We, the world as we experience it, live on a PLANE THAT HAS A SPECIFIC FREQUENCY. Maybe we are whole cause there are waves all around us that push us together. Leave the FREQUENCY RUNNING ON A PLANE for a looooooong time and you get our world?
