superposition / collapse

kyoto

Hello, I need a help for making a short visual presentation of superposition and wavefunction collapse. It will be a power-point presentation for young students.

I have an idea to show a superposition as a "perfect noise", which can be visually achieved as a uniform gray background or total blur (no difference between pixels value).

But what happens when we make a measurement?

I have an idea to show it as kind of spotlight ring (measurement) "lit" onto this uniform backround, disturbing the superposition, so the noise appears in the ring. In this noise each pixel value is different, which would show the state pinned down during measurement. How would you show this subject in a simplest way possible?
