How do I make cake balls. Small

Thanks!

Break up cake into fine crumbs. If necessary add some liquid (flavoring, cream, icing, jam, or most anything even semi-liquid) to make it slightly mushy - just enough for the crumbs to stick together.
Roll into marble sized balls; chill well. Dip into melted chocolate. Can roll in or sprinkle with jimmies, course sugar; cocoa powder; coconut or fine chopped nuts, etc.

I just did a tree 2 days ago with cake balls, bite size...I used latex gloves and rolled them out in my hands...check out my photo for the size.
for the strawberry flavored cake I used a small amount of that yougurt you drink in mixed berry flavor.
