What is a Rainbow?

Does anyone else remember this book series? I think we had all of them as a kid 🙂 Anywho I thought it was a good book to read before we made crystal rainbows. 

Measuring out 8 cups of water to boil. 

While waiting for the water to boil we read the book and got pipe cleaners out to match the rainbow. 

This is what we came up with. 
We did 1 cup of borax.
mixing 1 cup of borax in the boiled water

approximately 24 hours later this is what we found.

Added cotton ball to cover the ends and then I put fishing line tied around it and hung it from out front window.
I LOVE being a homeschooler!!
