Effect: There are three screws with nuts. All bolts are different, marked with three colors: red, blue, and yellow. All parts are examined by the spectators. Now the spectator is asked to choose one of the bolts. The choice is absolutely free. The three bolts are then thrown into a box, and the box is shaken by the magician. When the spectator opens the box, the nut from the chosen bolt has loosened and now lies separately in the box.
 
Everything may be examined. The trick may be repeated instantly.
 
CONDITION NOTES:  Very good condition with some minor wear.
