But what if you could toss a single coin (or other object) into your hand and your spectators heard it slapping against your hand when it arrived? Well now you can, because I'm going to teach you my Fingernail Click Vanish!
The sound is created by the object striking the back of your finger nails. It's really great for larger objects (such as a cigarette lighter or chap stick) because your audience will hear the "heavy" object being tossed into your hand. This video shows several different objects vanishing, followed by a rear view so that you can see the mechanics of the vanish.
Another nice feature of this vanish is that your hand remains flat when you display and toss the object. After it makes contact with your nails, they push it into your fingers so that you can curl them around the object at the last moment.
Enjoy, and Merry Christmas!
