• Glass bottle with a lid
• Water
• Borax powder
• Clear glue
• Food coloring (optional)
Instructions:
1. Fill the glass bottle about 1/3 full with water.
2. Add a few drops of food coloring to the water, if desired.
3. Add 1 teaspoon of borax powder to the water and stir until it is completely dissolved.
4. Add 1 tablespoon of clear glue to the water and stir until it is combined.
5. Watch as the mixture begins to form blobs.
6. Add more borax powder or glue if necessary to adjust the consistency of the blobs.
7. Close the lid on the bottle and shake it vigorously for a few seconds.
8. Observe the blobs as they move and interact with each other.
Facts about the Blobs in a Bottle Science Experiment:
• The blobs are formed when the borax powder reacts with the glue to create a polymer.
• Polymers are long, chain-like molecules that are made up of repeating units of smaller molecules.
• In this experiment, the repeating units are made up of borate ions and glue molecules.
• The borate ions interact with the glue molecules to form cross-links, which are what give the blobs their shape and structure.
• The blobs are able to move and interact with each other because they are suspended in water.
• The water provides a medium for the blobs to move through and also helps to keep them from sticking to each other.
• The Blobs in a Bottle experiment is a great way to learn about polymers and how they interact with water.
