The very first yo-yo trick to learn.

Gravity pulls the yo-yo down, and you pull it back up.  Let the yo-yo drop toward the ground, then give it a steady pull before it reaches the end of the string.  See how many times you can do it in a row without stopping.

Tip:

– If the yo-yo spins at the end of the string, just give it a sharp tug and it will come back up.
