What happens to the Flubber when...
it is stretched?
it is rolled into a ball and bounced?
it is stretched over the opening of a 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.
