Improve finger dexterity. Playing a musical instrument with several keys like the flute or the saxophone, cross-stitching or twirling pencils through your fingers all promote flexibility in your fingers. These activities also help you move your fingers and objects faster.
Choose one finger trick to learn. Almost every magic trick uses sleight of hand or fingers to perform the act. Trying to learn too many tricks at once hinders your ability to perfect the trick. As your skill improves, add more finger tricks to your repertoire.
Learn how to position your fingers. When you use finger tricks to speed solve a Rubik's cube, the tricks rely more on the positioning of your index and ring fingers than any other factor. Properly placing your fingers on the cube allows you to spin the cube sections faster.
Know how to palm objects and use props. Magic coin tricks often involve dropping the coin into position where your hands join the middle and index fingers. Props like a thumb cap allow you to stuff paper or handkerchiefs into your hand and make them disappear.
Be creative. The words, or patter, which accompany magic tricks occupy the audience and help keep their minds off of the trick's details. Find a style that fits your personality so your act doesn't sound forced.
Keep the mystery of the trick. Practice where people won't see the steps involved in the trick. Once you can perform the trick flawlessly, then start showing it to people. Limit how many times you perform the trick in a given time period.
