This is my favor opener trick. Instantly amaze people even without any word. I use the Funkenring which is handmade in Germany by ZZM, and make some optimization on it. You can see the flash is so big and far going. The people will think that the flash comes from your finger ring, so you can even take off the ring to people for examination before their eyes. That's right! The gimmick is almost invisible in your hand. You can easily load it into your pocket while people examine the ring. Funkenring is really a cool stuff that every magician should get one!
