I recently published my "Invisible Candy/Cookie Jar" effect and routtine under "Dollar Store Magic" on my site. The trick introduces two principles new to magic, which I hope will open up further possibilities for other magic inventors to use in developing effects of their own. The principles are contained in the visible production of candy (or other small items) from the center of a clear plastic "cookie jar," and a see-through translucent candy bowl which is empty one second, and filled with candy the next. To the best of my knowledge, neither of these principles has been used in magic before.
It is always exciting to chart new territory and especially to come up with a basic simple principle that has many interesting applications.
