Rainbow raining

Ellen is now 13 today and a smile came to her face when she opened the final present with the Disco Magic Showerhead. After a quick installation, her regular shower was transformed into a brilliant display of innovative LED colors.  The colors change (by only using the water pressure) about every 30 seconds from red, pink, lavendar, green, blue, orange, yellow and cycles back again. 

The key question was - did she pin it?
