Floating Rosary.... amazing idea. You can teach kids about the rosary in such a fun way. As you put the helium balloons together you pray. Then you let it go when you are finished and you will see it float away, heavenly. Buy balloons for arches they have tips on both ends. Use simple cord that comes with balloons to hold the ends down while you finish praying. (have 3-4 kids hold the cord) then just let go. It was amazing.
