Why these effects work:
They are broken down in a fashion in which the spectator will not be expecting anything.
The effects are executed fast, and hard requiring body-flow and timing... thus they become almost impossible to be traced.
Phone be gone: Take a phone and crush it while its in its case. Then pull a rubber band out and pull it out of the rubber band. (Spectators phone is optional under certain conditions)
Billy: A spectator signs their bill. You then place it into the deck box and have the spectator select a card. The bill then vanishes from the box wrapped around the selected card. It then vanishes off the card to your pocket. (Can be done in the spectators hand as a option)
Quick Clip: Take a regular ring and paper clip. Toss the paper clip up to the ring and have them link instantly.
