Object Lesson about God's Love with a Science Experiment for Valentine's Day

I found this treasure on Pinterest.   This is perfect not only for your Science and/or Bible class but for co-op, Sunday School class, or youth group. 

Creative Bible Study Lessons & Ideas has so many great object lesson ideas along with great Bible study ideas as well.  This one caught my eye for two reasons:

1.  My friend, who is a leader in her youth group, actually DID this lesson and share on Facebook how awesome it was and how the kids really "got it". 

2. It was perfect for Valentine's Day.

The  lesson is about how our hearts are empty without God, how He fills them, and then that we need to share Him with others.
