The basic effect is well-known: a screw unscrews itself from the nut, without being touched. Up to now this was done using a wire but that requires quite a bit of preparation and it doesn’t work perfectly every time. With ‘Twist Off’ you get the same effect almost automatically; and with a little practice you’ll be to redo the trick as quick as you like.
Show the screw and the nut separately, screw them tight and place the assembled piece on the table. Next, cover the prop with a silk; something is clearly seen to move beneath the silk and when, soon after, you take away the silk the screw has unscrewed itself from the nut.
‘Twist Off’ is made of copper and manufactured with great accuracy. Intricate design, no invisible wires and only requires limited preparation.
