Dump glue into a medium bowl, then add yellow paint and mix until the desired color is achieved (add more paint, in small amounts, if necessary).

Add starch slowly, stopping for "stretch" test often.

When slime is at the proper consistency (no sticking to hands when played with), set aside.

Paint lid with denim paint until well-covered. When completely dry, put slime into the jar and close with the lid.

Flip jar over (lid on bottom) and apply one or two googly eyes with a hot glue gun. Use a black marker to draw the mouth.
