How do I recorrect the top?

Circle your hand the opposite way the top is spinning. Should straighten it out.

Check the sticky at the start of this forum,
Getting Started with Spin Tops.
There is a video on it, and other great pointers.

Think of balancing a broom on your hand. When it tips forwards, you move your hand forwards with it to compensate.

Now do precisely the opposite; if the top tilts forward, move your hand backwards. Precession is weird.
