2 cups white glue
1 1/2 cups water at room temperature
food coloring or colorations water color
1 cup hot water
2 1/2 level tbsp 20 mule team borax
Combine glue and room temp. water. Add food coloring or colorations.
In larger bowl, combine hot water and borax, stirring until the borax is completely dissolved. Slowly pour glue mixture into the borax mixture. (You must do this exactly - glue mixture into the borax mixture, or it may not work.)
Squeeze space Mud between fingers until most of the water is worked out. (There will be some water left.)
This mixture will not stick to dry surfaces. Kids (and adults) can cut Space mud with a plastic knife, cut with scissors, tear it, watch it slowly melt off the edge of the table. It even bounces! Lasts indefinitely in an air tight container.
