Have you ever blown bubbles at night? Your kids will think you are strange for suggesting it, but when you throw a flashlight in, they will love the idea!
Grab a pack of colorful tissue paper. We got this pack from the
Dollar Tree, for yes, $1.
Cover a flash light with tissue paper and place a rubber band around it
to keep it in place.
When you turn it on it will reflect the color of the tissue paper.
Blow bubbles and shine the colorful flash light on the bubble. It of course reveals a rainbow on the outside of the bubble, but when you look at the center of the bubble it will reflect the color of the tissue.
