Is there any possibility of acquiring (or learning how to make) a magnet ball. We know that the regular balls are just normal raquetballs, but what strength, size, etc. magnet would be inside of it? Is there a way to either recreate one or borrow one pre-tournament?
A: The type of magnet used in the magnet ball can be found in the BOM which can be downloaded from the FIRST website

To make a magnet ball a ~1inch long slit is made in the racquet ball and the magnet is slipped inside. The slit is then glued back together with super glue.
