The experiment is easy to do, but difficult to understand. It consists of setting up a light source on one side, facing a barrier (such as a piece of cardboard) that has two slits in it to permit some light to pass through to a distant wall on the other side. If both slits are open, then one pattern is observed on the distant wall. But if one slit is covered, then a completely different pattern is then seen on the distant wall.

The experiment can also be done with particles, such that a series of particles are directed at a grid, or other similar device, while observing the pattern on the other side.
