Homemade Silly Putty

We have a science kit which includes the recipe for making homemade silly putty. It also has some powder that will make the putty glow in the dark.

I made some with Joseph. Not surprisingly, it was a big hit and the younger girls wanted silly putty as well.

I was busy so asked Naomi to work with them. Well, she came through in spades!

Angela enjoyed watching.

She even added food coloring to make it in different colors.

We DID have a brief talk about the science.  A borax and water mixture is added to a white glue and corn starch mixture. The borax causes polymerization of the glue/corn starch.
