Abstract from "Beats Entangeld" - Spoken Word about Quantum Physics by Srdjan Nikolic, Drums by Florian Krause - enjoy!
Double slit experiment proves that one particle, say photon or electron, can go through both holes and interfere with himself, behaving like a wave. And not just some ordinary wave, but a wave which is more metaphysical then physical: the wave of probability.
And if you want to know,
through which hole
did the particle-wave go,
if you do the so called “which way experiment”,
suddenly there is no wave anymore.
All you left with is a particle, just as we used to know,
that goes either-or
through either one or the other hole.
