Flubber

What happens to the Flubber when... it is stretched? it is rolled into a ball and bounced? it is stretched over the opening of the jar? an object (golf ball, etc.) is rolled on it? What else can you do with flubber? ...make it and find out! A Closer Look: 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. (You can get white glue in bulk from a school supplies source. Keep this stuff away from carpet and hair as it will stick. If necessary, white vinegar can act as a solvent.) Thanks to my cyberpal Julie for this recipe!
