rainbow peepholes worked great!!

My students loved using the rainbow peepholes when we were studying a science unit on light. They were amazed how the diffraction grating in the peephole center breaks apart all of the colors that can be found in white light. They loved this project!

Great!

I love these little tokens of Rainbow Medicine! I keep some with me wherever I go so that if/when I have a sweet encounter with a stranger who is kind, funny or even sad and needs a lift; I will gift them a Peephole to bring a touch of joy and magic to their day. It never fails to deliver a spark of delight and I love the looks on their faces when they hold it to an eye and see the Rainbows!
