Making Flubber...
Container 1:
¾ cup warm water
1 cup white glue
Food colouring (a couple of drops)
Container 2:
2/3 cup warm water
½ teaspoon Borax
1. Mix the ingredients in each container thoroughly. Take note of how they both look, are they very different?
2. Pour the contents of container 2 into container 1. Lift and turn the mixture with a spoon until nearly all the liquid is gone. Gently squeeze any excess liquid from out of the Flubber.
3. What has happened? How does it feel? What happens if you stretch it? If you roll it into a ball?
***Polymers are made by a chemical reaction, they are long chains of repeating units. When the 2 solutions are combined, polyvinyl acetate chains (from the white glue) are linked together in a 3-dimentional arrangement by Borax ions (from the Borax) and other chemical bonds. This produces the sticky polymer that we call Flubber.
