Loved this movie! The sequel not so much...... Question

Hello, Wizards of Waverly Place the Movie is in my top 10 favorite movies of all time. Unfortunately though The Wizards Return........well....not so much. Anyway, I'm currently writing a review for The Wizards Return: Alex vs Alex and there seems to be one thing I can't quite remember? It's about Dominick's super-weapon?

What was it supposed to do exactly? Like what IS IT?

I mean, I get that it shrunk all mortals and trapped them in tiny plastic balls (I get that) but, was that the only thing it could do?

Help is much appreciated.

Thank you.
