Failure experiment--shaving cream and food coloring

We tried this word of mouth experiment - and somehow did it wrong:

4 simple ingredients-jar, dye, shaving cream, and time.

Maybe we put too much shaving cream on top of the jar?!

The blue was suppose to turn the foam (shaving cream) blue and drip down like RAIN---nope; it didn't happen.  This picture was 40 minutes after waiting---and it didn't change.
