Stretchy Be very careful and real all warning labels when handling Borax or Borax-based solutions. Use caution when making "Stretchy.” Also make sure small children don't put these or any other mixtures into their mouths. 4 ounces white glue 1 1/2 cups water 1 teaspoon Borax powder* Food coloring Mix glue, 1/2 cup of the water and 10 drops of food coloring in small bowl. Combine borax and a cup of water in medium bowl. Gently pour glue mix into the borax and stir until well mixed. Scoop the Stretchy out of the water and knead until dry enough to play with. Store in sealed container for several weeks. Stretchy is great for pulling apart. Stretchy also dries out quickly with a lot of handling.
