If you do this at home, it will take a little while for the colors to really soak in. My Hubby-Man talked me out of adding more food coloring and I am glad he did because the colors turned out to be beautiful.
I let it soak for a little over an hour, like Stephanie suggested, than put it in four separate pans to dry.
Some of the manicotti in Bam Bam's bin cracked, and the colors are not entirely uniform in either bin but they are bright and the boys have been enjoying them so far today. I think it is a great activity for just before St. Patrick's Day because you can tie it in with rainbows.
Linking up to these great parties!
