I found this idea on another one of my favorite websites: http://www.notimeforflashcards.com
I would highly recommend using Chinet paper plates instead of the regular ones. With all the paint on them, they kinda got flimsy. You cut out a heart shape in 1 paper plate and then tape a ziploc baggie over, so it becomes see thru. Just cut the baggie in half. Then, you can fill it with whatever you want. I wish I had had some confetti to put in there. The kids enjoyed painting and "ShAkInG" their musical Valentine!
