I've seen demonstrations of people dunking things into fluid with the same IOR before, but showing the same effect by using an eyedropper like this makes it look way more interesting.
You could probably make some pretty cool stuff with this effect, like a snowglobe with figures that will randomly "disappear", or a clock made out of air bubbles inside of a thin tank.
