double flubber

Back when Miss Ella was two years old we learned how to make flubber at OMSI in Portland. Here is the recipe. Flubber is a polymer made by a chemical reaction. Polymers are very long chains of repeating units. When the two solutions are combined, polyvinyl acetate chains (a polymer from the white glue) are linked together in a 3-dimensional arrangement by borate ions (from the Borax) and other chemical bonds. This produces the thick, sticky polymer called Flubber.

After thinking about my experience with camp I emailed the private school where I have Ella on the waiting list for first grade. I was going to try out the public kindergarden, but I think I just got my first peek at the status quo. I'll start planning the bank robbery.
