Owen4ever... mate I expect a bit more from you. It takes some people longer to master some tricks, especially if they use the wrong technique. there are a few tips we can give to help the guy out. Maybe it will take him 15 minutes to learn the trick once he knows a few tricks.
When the ball is coming down, try to lower your neck/back down with the ball just before it hits the neck. This will reduce the bounce of the ball and allow it to land calmly.
Good luck and feel free to ask more questions if you have any.
