here are some receipes that i have collected.. i tried the one with the
white glue last year and it worked when i did it but not forthe kids..if you
anyone has a better one let me know.. i am about to try number 3
first Slime recipe
Corn starch
Water
Food coloring (optional)

Put cornstarch in bowl. Add enough water to make a paste. If desired, you
may also add food coloring. This makes a messy slime that goes from liquid
to solid, and is great fun to play with. This recipe (or green playdough) is
especially fun to make after reading Bartholomew and the Oobleck by Dr.
Seuss!

second Goopy Slime
2 Cups Water
1/2 Cup Cornstarch
Food Coloring

Boil 2 cups water in a medium saucepan. Add cornstarch while stirring. After
that is mixed well, add food coloring and stir. Remove from heat and cool to
room temperature. Make sure they play with it on a plastic covered surface.

Most Slime and Putty recipes use some amount of sodium tetraborate,
commercially available as Borax. Authentic commercial Silly Putty is made
from Borax and silicone oil -- unfortunately I haven't got details on the
precise ratio. [As an interesting aside, Silly Putty was apparently invented
in 1943 in a failed attempt to produce a synthetic rubber. The large
chemical company which invented it sent samples to more than 12,000
engineers around the world, but no practical use for it could be found.]

third SLIME. (this one sounds good-i will try it soon
Many toy stores sell one form or another of colored Slime. Usually they come
in small tubs, are slightly unpleasant-smelling, and are cold and clammy to
the touch (apparently because of an endothermic reaction). The recipe below
is the exact recipe for commercial Slime, and makes a small, palm-sized
amount:

* 1 fluid ounce of 5% Polyvinyl Alcohol (acid-free art glue) solution (in
water)
* several milliliters of 4% sodium tetraborate (Borax) solution (in water)
* a few drops of food coloring.

Mix the food coloring with the Polyvinyl Alcohol solution. Add one
milliliter of the Borax solution and stir like crazy for 2 minutes. Adding
more Borax solution will yield thicker slime if desired; nice thick slime
can be had with approxiately 4-5 ml of Borax solution per fluid ounce of
polyvinyl alcohol solution. Store the slime in a clean, covered container.

fourth How to Make Slime
From your Chemistry Guide

There are lots of recipes for slime. Since most recipes are easy, look for
one using ingredients you have on hand.

Difficulty Level: Easy Time Required: 15 mins

------------------------------------------------------------------------
Here's How:

1. Pour the glue into the jar.
2. Fill the empty glue bottle with water and stir it into the glue.
3. If desired, add a few drops of food coloring. Otherwise, the slime will
be an opaque white.
4. In the bowl (not the glue mixture), mix one cup (240 ml) of water into
the bowl and add 1 teaspoon (5ml) of borax powder.
5. Slowly stir the glue mixture into the bowl.
6. Place the slime that forms into your hands and knead until it feels dry.
(Don't worry about the excess water remaining in the bowl.)
7. The more the slime is played with, the firmer and less sticky it will
become.
8. Have fun!
9. Store your slime in a zip-lock in the fridge (otherwise it will develop
mold).

Tips:

1. Use white glue, such as Elmer's brand. Most 'school glues' do not have
the correct composition.
2. Don't eat the slime - it isn't especially toxic, but not good for you
either!
3. Should clean up easily. Remove dried slime after soaking with water.
