Use equal parts of stayflo liquid starch and elmers white glue. Mix and tada slime. You can add food color to the elmers before you mix to make colored slime. Make sure you get a dark color to the glue for the color to show well. We also mix in glitter and such at time.

That stuff is a hoot. I love it!! We made it for the preschoolers all the time.

It is easier to do if you put the starch in the cup fisrt then the glue slides right out.

Sometimes it takes a long time to get the right consistancy, just keep mixing.
