Hello and welcome to rotate. This app is for any magicians who want to perform the self winding nut and bolt.

Quick instructions: Load the app which looks like a standard watch face. When you are ready to perform simply press the top button once and you will feel a short vibration to let you know its ready. 

4 seconds late the magic will happen. This will last for 10 seconds then stop. This should be more than enough time to unwind any small nut and bolt

Enjoy
