Luke stood in front of the mirror, which hung on the back of his bedroom door. He picked up the vial with the bluish liquid and took a sip. His grin matched that of a Cheshire cat until it, too, disappeared. Luke watched the mirror. Soon, he saw the vial seemingly floating in midair in front of some clothes that also hung there with no visible means of support. He sat the vial down picking up the one next to it containing a reddish liquid. He took a sip waiting for the results.
Unbeknownsted to him, a fly was buzzing around the room. The fly landed on the vial with the bluish liquid. If only Luke had known that. It buzzed around, landing here and there and everywhere. It unwittingly picked up a few drops of liquid on its legs from various containers. When the invisible hand of Luke put the vial of blue liquid down in order to exchange it for the red liquid, the fly perched itself on the vial’s edge. It inadvertently shook some of the drops from its leg into the blue liquid and took off. Luke’s now visible hand put the vial of red liquid down, proceeding to cork both vials.
