It's like explaining to a black dot on a white paper how a 3 dimensional object makes up a pencil that can make black dots. Would a dot be able to easily understand how such things would work, dimensions included? For the black dot on paper, making a pencil strike would look like pure magic from their perspective.
As you're mentioning that now - did you watch the film "What the Bleep do we know?". It's about quantum physics and their meaning and is quite interesting. There also is this animated bonus film which I think is done pretty well and also describes what you just did: English: Dr. Quantum - Double Slit Expermint Dr. Quantum - Flatland
