St. Patricks Day has passed, but that doesn't mean the rainbow activities have to end. A set of glasses, that good old food coloring, plus a little water, and you've got yourself a rainbow xylophone.
Little Page Turners suggested this activity for St Patricks Day but posted about it a couple of summers ago here. It's simple, takes few materials, and seems like a great way to reinforce color or teach about tones.
