========== Check this outI'm using this speaker to vibrate a petri dish containing silicon oilNow if I take this toothpick and make a little droplet on the surfacethe droplet will stay there, hovering above the surfaceThe droplet is actually bouncingand it will keep bouncing for a very long timeNow the reason for this is a little layer of air between the droplet and the surfaceAnd the droplets bouncing so rapidly that that layer never shrinks to about 100 nanometersWhich is what it would take for the droplet to recombine with the oilNow, every time the droplet lands on the surface, it creates a waveBut this is a special type of waveDriven by the vibration of the oil bathIt is a standing waveMeaning that it is not traveling outIt's just oscillating up and downSo the...
