Have you watched Flubber movie 1997? If yes, then you know that in this movie Robin William makes a green rubber-like substance named “Flubber”. In this experiment, we will make flubber (It won’t talk! SORRY!) But you can play with it. You will also understand the science behind it.
Precaution: Always wear safety goggles and hand gloves when dealing with chemicals. Also, take the permission from your parents for the experiment, or involve them.
Things You Will Need
- Warm Water
- 1 cups of Elmer White Glue
- 2 tablespoons of Borax
- Green Food Coloring
- Airtight bag
How to Make
- Pour ¾ cup of warm water and 1 cup of white glue in a bowl.
- Add 2 to 3 drops of food coloring in the bowl and stir the mixture with a spoon
- Pour ½ cup of warm water in another bowl, and add 2 tablespoons of borax in it. Stir the solution to completely mix the borax with
- Pour all the solution of borax in the first bowl, and stir the mixture well with a spoon.
- Pour all content of bowl in an airtight Close the bag tightly and make sure no liquid is leaking from the bag.
- Knead the mixture in the bag with your hands from outside for 5 to 10 minutes.
Your flubber is ready!
You can remove it from the bag and play with it. If your flubber is sticky then let it dry a little bit, then it will be okay.
How it Works
The flubber you made is a Polymer. You made it by mixing borax and glue together. Borax acts as a connector (crosslinking agent) for the glue molecules. When glue molecules are joined together and formed a large molecule chain you got a gel-like substance.
- Try to make a rainbow flubber. You can make it by preparing seven different flubber, but kneading all the seven flubbers together when they are still sticky.
