Make Your Own Goo
Goo is a fun little product that kids seem to love. It also goes by the fun names of slime, flubber and gak. These products are sold under a few different names and by a few different companies, but they can also be quite expensive. It's much easier and better to make the same thing at home, and all it takes is a few simple ingredients. The borax is the only thing that's difficult to find, but most stores stock it near the laundry detergent and other cleaning supplies.
1/2 cup of white glue
1 Cup of Water
Food coloring (optional)
Glass or Ceramic cup
1 Teaspoon of Borax or Non-Bio Gel
Additional 1/2 cup water
Begin by mixing together the glue and water in a small bowl until it's thoroughly mixed. For colored goo, add a few drops of food coloring to this mixture and stir everything well. In a separate bowl, mix together the borax and a 1/2 cup of cold water.
Stir the water and glue mixture slowly, while pouring the borax and water combination into the bowl, and keep mixing. Continue mixing the product until it takes on a goo like consistency. For a thinner slime like consistency, add a small amount of additional water to the mixture. Now the goo is ready for playing. To keep it fresh, store in an airtight container when not in use.

Teachers use the goo recipe in the classroom to show students how a liquid becomes a solid. This relies entirely on the borax and the chemical reaction it has with water and the glue. As soon as the borax touches water, it begins fizzing. Yet when it reacts with the glue, it forms a semi-solid state. The kids love playing with the final product, but the adults love the lessons they learn in the process.
