We’ve made slime a few times and this is the best recipe I’ve found so far. It’s very slimy and smooth…. and turns out great! We love squeezing it through our fingers!! We used neon food coloring so the color was nice and bright!
Need:
Borax (can bought in the laundry detergent aisle.)
White glue (like Elmers)
Food coloring
Ziploc bags
measuring cups and spoons (We have some set aside for projects like this)
1. In a bowl mix ½ teaspoon Borax with ½ cup of water. Stir until dissolved.
2. In another bowl, mix ½ cup of white glue with 1 cup of water.
3. Pour the glue mixture into the zipper bag. Then, slowly pour in the borax mixture. Add a few drops of food coloring
4. Seal bag, knead the mixture until you have slime. 
Keep your slime in the sealed bag in the refrigerator when not playing with it to keep it longer. Unfortunately it may eventually dry out or grow mold. Just throw it out and start again!
How It Works:
The borax is acting as the crosslinking agent or “connector” for the glue (polyvinyl acetate) molecules. Once the glue molecules join together to form even larger molecules called polymers, you get a thickened gel very similar to slime.
