 - Therefore, in order to make the Ploopy Nano function better, you'll have to remove a bit of the shine on the ball.

+## Step 18 (OPTIONAL): Rub the ball with toothpaste

+- This is an optional step. Only do this step if you complete the rest of the instructions and find that the cursor tracks poorly.
+- If the ball is very reflective, the reflectiveness of the ball will interfere with the function of the sensor, causing poor tracking.
+- A simple, effective fix is to get about a teaspoon of toothpaste onto the ball and rub it vigourously for about two minutes.
+- Toothpaste is quite abrasive, so it will effectively "sand" the ball, causing it to become less shiny. It will also cause the ball to smell great!
+- Once done, wash the ball (and your hands) well and try the ball again. The tracking should be greatly improved. If it isn't, try this step again.

 Plug the trackball into your computer. If you move the ball, it should move the cursor.

 The bearings are a bit scratchy when they're new. To prevent them from jumping around during initial use, spin the ball with some Latin dance vigour for about three minutes. That should be enough to break them in.
 
 The bearings will take about a week to become fully broken-in.
