This is our favorite slime recipe. This slime uses Borax and has the a consistency ranging from Slime to Silly Putty, depending on how much Borax and water solution you add. The end result is less messy and most like "Slime" from the store.
1 cup warm water (this is for the Borax mixture) plus 1/2 cup water (this is to mix with the glue)
1 tsp Borax
1/2 cup (One 4 oz bottle) Elmers Glue (Clear Glue for More Vibrant colors, White Glue for more opaque, pastel)
Measuring Cup, Measuring Spoon
Portion cups, ziplock or small container
Whisk (handy for mixing the glue and water thoroughly).
Spoon for mixing the slime mixture until it forms into a solid.
In a bowl mix 1/2 cup Elmer's glue and 1/2 cup water. Mix thoroughly!
Add the food coloring, mix until the color is evenly distributed. (Important: Add color now, color will not rub off on hands when handling)
In a cup of warm water add 1 tsp Borax, mix so as it's as evenly dissolved as possible. (You will use only part of this mixture)
Pour about a 1/4 cup of the Borax mixture into the glue/water mixture. Stir the until it starts forming into a solid.
Add more of the Borax mixture if you want a stiffer Slime. We felt ½ cup to ¾ cup was the best consistency. The more you add the more solid a slime will result. Keep in mind it will firm up after sitting for a few minutes and while handling. Adding the full cup will result in a Silly Putty like consistency, flexible but not stretchy.
Once it starts forming you can start to scoop it up in your hands and discard excess water.
Let it set in a bowl or container for 10 minutes, it will firm up a little and become less sticky.

Liquid Starch Slime Recipe
This method using Liquid Starch makes goopy, stretchy slime. Great alternative if you can't find Borax.
1/2 cup Liquid Starch
1/2 cup Elmers Glue (Clear for More Vibrant colors, White for more opaque, pastel)
1/2 cup Water
Glitter, confetti, or food coloring (optional)
Pour the glue and water into a bowl. Mix thoroughly until the mixture is even.
Add your confetti, glitter or food coloring (optional)
Pour 1/2 cup starch into the bowl and mix until a solid starts to form.
Use you hands to scoop the slime out of the bowl. Pour out the excess water.
Store in a portion cup, container or ziplock. When you remove to use, there will be some water in the container, simply discard.
Rainbow and Glitter Slime
Use either method and make each color in a separate bowl. We reduced the recipe to 1 TBS of glue for each color just to test. This will fill one 2 oz portion cup.
Easiest method is to use Elmer's Glitter Glue. They are vibrant and sparkly. If you want to use your own glitter, use either recipe and add glitter when you add the food color.
Slime made with Elmer's Glitter Glue
We used Clear Elmer's Glue and added some star Confetti. Cute for a themed party.

Tips and Suggestions
Use Elmer's Glue! We tried other brands and the slime just doesn't form.
If this is for a class size it would be most cost effective to purchase the gallon sized Elmer's Glue.
Borax and Liquid Starch can be found in the laundry section at Walmart
For Rainbow Slime we used Clear Glue and Wilton Food Coloring Gels. We made smaller portions in 6 styrofoam bowls.
We used clear portion cups found at Walmart to store our slime.
Portion Cups With Lids to Store Slime
This is what happened when we used another brand of inexpensive glue.
