We suggest a carousel model to achieve even results. After serious and painstaking scientific tests it has been determined that 3 seconds is about right. You can see it quite nicely if this is done in a darkened kitchen. The result resembles a miniature lightning storm with sort of a blue flame running along the outer edge. The end product usually resembles a mosaic and we would not expect it to contain the same data after this technique as it had prior to the technique.

Tossing them out an open window may relieve a small percentage of stress, with even higher levels of stress reduction obtained by flinging them back and forth in the back yard until the binders let go. If you accompany this with wild screaming while barefoot it seems to be the most effective. A caution here is to note how far away you live from a mental institution. Mental institutions usually write these manuals, and don't take kindly to viewing their work scattered about your back yard with binders and pages in disarray. Most computer related furniture does not burn well in its natural state.
