"This glass shines. It does so by guiding extremely tiny kernels (which repel from others) through a sort of 'road' where they pass easier. This road leads to itself only.
There is a place that pushes these kernels away to an area on that road they're pulled towards. When it encounters a sort of barrier, it hits that, and splats like a fruit; that's light."
Or put even easier:
"There's a place that makes tiny kernels. Those kernels are thrown from that place, following a path; when they hit their target, they scatter, giving light."
Edit: replaced tomato with fruit.
What's a tomato?
